Answers

Answer 1

To write the name "Sodium Chloride" from a chemical formula, follow these steps:

1. Identify the elements present in the formula: In this case, the formula is "NaCl," which contains the elements Sodium (Na) and Chlorine (Cl).
2. Write the name of the metal (cation) first: In this case, the metal is Sodium (Na). So, the first part of the name is "Sodium."
3. Write the name of the non-metal (anion) with the suffix "-ide": The non-metal is Chlorine (Cl), so the name changes to "Chloride."
4. Combine the names of the metal and non-metal: The final name is "Sodium Chloride."

To write the chemical formula "NaCl" from the name "Sodium Chloride," follow these steps:

1. Identify the elements from the name: In this case, the name is "Sodium Chloride," which contains the elements Sodium (Na) and Chlorine (Cl).
2. Determine the charges of the elements: Sodium has a +1 charge as a cation, and Chlorine has a -1 charge as an anion.
3. Balance the charges to form a neutral compound: Since the charges are +1 and -1, they balance out, and you don't need to add any subscripts.
4. Write the chemical formula using the element symbols: Combine the symbols to form the formula "NaCl."

What is energy, and what is its unit of measure?

Answers

Answer:

Energy is measured in joules. And it is a derived unit. An example that you use in energy  is horsepower.

On the web an easy definition: Kinetic energy is motion; it is the motion of waves, electrons, atoms, molecules, substances, and objects.

Also, everything consists of energy. For example, when you turn a page from a book, that is using energy. Or when a ball is rolling down a ramp, it is using kinetic energy. You can also have potential energy, which is the energy stored in something when it isn't moving. For example, when the ball is about to roll on the ramp, it is in its starting point with potential energy.

And finally elastic energy:

Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.

For example, an elastic string. When you stretch it, it is the potential anergy stored in the string you are stretching. When you release it, it flies in the air and changes to kinetic energy.

Answer:

Energy is the ability to do work (Quantitative property that must be transferred to an object to perform work on)

Answers

An Arrhenius base is a molecule that when dissolved in water will break down to yield an \(OH^-\)or hydroxide ion in solution.

What is Arrhenius base?

An Arrhenius base is a compound that increases the \(OH^-\) ion concentration in aqueous solution.

An Arrhenius base is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or , \(OH^-\) ions in the solution.

Bases Properties

Arrhenius bases that are soluble in water can conduct electricity.

Bases often have a bitter taste and are found in foods less frequently than acids. Many bases, like soaps, are slippery to the touch.

Bases also change the colour of indicators. Red litmus turns blue in the presence of a base (see figure below), while phenolphthalein turns pink.

Some bases react with metals to produce hydrogen gas.

Acids (pH < 7.0) react with bases (pH > 7.0) to produce a salt and water. When equal moles of an acid and a base are combined, the acid is neutralized by the base. The resulting mixture will have a more neutral pH.

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons. In other words, it increases the number of \(H^+\) ions in the water. In contrast, an Arrhenius base dissociates in water to form hydroxide ions \(OH^-\).

Example, sodium hydroxide, is added to an aqueous solution. NaOH dissociates into sodium, \(Na^+\), and hydroxide, \(OH^-\) ions.

Time Evolution in a Three-State System [15 points] Carbon dioxide is a linear molecule (OCO) that can pick up an extra electron and become a negatively charged ion. Suppose that the electron would have energy EO​ if it were attached to either oxygen atom, or energy EC​ if it were attached to the carbon atom in the middle. Call these states ∣L⟩,∣C⟩ and ∣R⟩, for left oxygen, carbon, and right oxygen. The energy eigenstates need not, however, have either energy EO​ or EC​ because there is some probability that the electron may hop between an oxygen atom and the carbon atom. (Assume that the probability of jumping directly from oxygen to oxygen can be neglected.)

Answers

The specific values of EL, EC, and ER will determine the precise behavior of the system and the probabilities of the electron being in each state over time.

To study the time evolution in this three-state system, we can write down the Hamiltonian matrix for the system.

The Hamiltonian describes the energy of the system and the transitions between different states. In this case, we have three states ∣L⟩, ∣C⟩, and ∣R⟩.

The Hamiltonian matrix can be written as:

H = [[EL 0 EC],

[0 EC 0],

[EC 0 ER]]

Here, EL represents the energy of state ∣L⟩, EC represents the energy of state ∣C⟩, and ER represents the energy of state ∣R⟩.

Since the electron can hop between the carbon atom and the oxygen atoms, we have nonzero off-diagonal elements in the Hamiltonian.

To solve for the time evolution of the system, we can find the eigenvalues and eigenvectors of the Hamiltonian matrix.

The eigenvectors represent the energy eigenstates of the system, and the eigenvalues represent the corresponding energies.

Once we have the energy eigenstates, we can determine the probabilities of the electron being in each state at a given time by calculating the time evolution of the initial state.

The specific values of EL, EC, and ER will determine the precise behavior of the system and the probabilities of the electron being in each state over time.

It is worth noting that the problem statement doesn't provide explicit values for EL, EC, and ER, so further information is needed to obtain a more detailed analysis of the time evolution in this three-state system.

When the rate of disappearance of O2 is 0.37 mol L-1 s-1, the rate of appearance of CO2 is ________ mol L-1s-1.

Answers

Thus, the rate of disappearance of O₂ is 0.37 mol L⁻¹ s⁻¹ , the rate of appearance of CO₂ is 0.2467 mol L⁻¹ s⁻¹

What is the rate of reaction?

The rate at which a chemical reaction moves forward is known as the reaction rate in chemistry. It is frequently defined in terms of either the concentration of a reactant that is consumed in a unit of time or the concentration of a product that is generated in a unit of time (amount per unit volume).

The equation becomes:

C₂H₄(g) + 3O₂(g) → 2CO₂(g) + 2H₂O(g)

Rate of reaction = \(-\frac{d[C_2H_4]}{dt}\) = \(-\frac{1}{3} \frac{d[O_2]}{dt}\) = \(+\frac{1}{2} \frac{d[CO_2]}{dt}\) = \(+\frac{1}{2} \frac{d[H_2O]}{dt}\)

It is given that, the rate of disappearance of O₂ is 0.37 mol L⁻¹ s⁻¹.

So, \(-\frac{1}{3} \frac{d[O_2]}{dt} =\) \(+\frac{1}{2} \frac{d[CO_2]}{dt}\)

or,  \(-\frac{1}{3} \frac{d[O_2]}{dt}\)  × (-0.37 mol L⁻¹ s⁻¹) = \(\frac{d[CO_2]}{dt}\)

or, \(\frac{2}{3} \frac{d[O_2]}{dt}\)  × (0.37 mol L⁻¹ s⁻¹) = \(\frac{d[CO_2]}{dt}\)

or, 0.2467 mol L⁻¹ s⁻¹ = \(\frac{d[CO_2]}{dt}\)

Thus, the rate of disappearance of O₂ is 0.37 mol L⁻¹ s⁻¹ , the rate of appearance of CO₂ is 0.2467 mol L⁻¹ s⁻¹

what minimal photon energy in ev is required to eject an electron from the ground state of a doubly ionized lithium

Answers

The minimum photon energy required to eject an electron from the ground state of a doubly ionized lithium is 8.62 eV.

This is due to the fact that ionization energy of doubly ionized lithium is 8.62 eV, which means that the minimum amount of energy required to remove an electron from the atom is 8.62 eV.

This is the amount of energy that the incoming photon must have in order to eject an electron from the ground state of a doubly ionized lithium atom.

In other words, the photon must possess at least 8.62 eV of energy to remove the electron from the atom.

a.1.21 x 10-3 M/S b.1.19 x 10-3 M's c.6.05 x 10-2 M's d.4.84 x 10-3 M/s

Answers

The rate of formation of SO₃ is 4.84 × 10⁻³ m/s. The correct option is d. 4.84 × 10⁻³ M/s.

To determine the rate of formation of SO₃, we need to consider the stoichiometry of the balanced equation. The coefficient of SO₃ is 2, which means that for every 1 mole of O₂ reacted, 2 moles of SO₃ are formed.

Given that the rate of O₂ loss is 2.42 × 10⁻³ m/s, we can use the stoichiometry to find the rate of formation of SO₃.

Rate of formation of SO₃ = (2 moles SO₃ / 1 mole O₂) × (2.42 × 10⁻³ m/s)

Rate of formation of SO₃ = 4.84 × 10⁻³ m/s

Therefore, the rate of formation of SO₃ is 4.84 × 10⁻³ m/s. The correct option is d. 4.84 × 10⁻³ M/s.

when an acid such as hcl reacts with a metal, such as zinc (shown here) the gas produced is

Answers

When an acid such as hydrochloric acid (HCl) reacts with a metal like zinc (Zn), the gas produced is hydrogen gas (H₂).

When hydrochloric acid (HCl) reacts with zinc (Zn), something interesting happens. The acid gives away its hydrogen atoms (H⁺) to the zinc. At the same time, the zinc gives away some of its electrons. As a result, hydrogen gas (H₂) is produced. The gas forms little bubbles that you might see during the reaction. The remaining zinc combines with the chlorine atoms (Cl⁻) from the acid to form zinc chloride (ZnCl₂). So, to sum it up, when acid (like HCl) and metal (like zinc) react, they create hydrogen gas and a compound called zinc chloride. The hydrogen gas bubbles out, and the zinc chloride dissolves in the remaining acid.

A single displacement reaction, also known as a metal-acid reaction, occurs when hydrochloric acid (HCl) and zinc (Zn) are in contact. This reaction results in the creation of zinc chloride (ZnCl₂) and hydrogen gas (H₂) as the zinc metal displaces the hydrogen in the hydrochloric acid. While the acid's hydrogen ions lose electrons and undergo oxidation, the zinc atoms acquire electrons and undergo reduction. It is a redox (reduction-oxidation) reaction because it includes both oxidation and reduction reactions.

Answers

The reaction of ammonia burning in the presence of a platinum catalyst to give nitric oxide is exothermic, but the exact value of heat evolved (kJ) cannot be determined.

The reaction being described is the burning of ammonia in the presence of a platinum catalyst to give nitric oxide. The experiment also mentions that the reaction evolves a certain amount of heat, measured in kilojoules (kJ).

To determine if the reaction is endothermic or exothermic, we need to consider the sign of the heat evolved. If heat is released (negative value), the reaction is exothermic, meaning it releases energy. If heat is absorbed (positive value), the reaction is endothermic, meaning it requires energy.

Since the question states that the reaction "evolves" heat, we can assume that the value of heat evolved (kJ) is negative. This indicates that the reaction is exothermic and releases energy.

Is it coating iron pipe with Zinc or connecting a zinc rod to a
iron pipe, which is advantageous to protect the Fe surface from
undergoing corrosion? Justify the answer

Answers

Connecting a zinc rod to an iron pipe offers advantages in protecting the iron surface from corrosion. The zinc acts as a sacrificial anode, corroding in place of the iron and providing uniform and extended protection to the entire iron pipe.

Connecting a zinc rod to an iron pipe is advantageous to protect the iron (Fe) surface from undergoing corrosion. This process is known as cathodic protection, where the zinc acts as a sacrificial anode. Here's the justification for this answer:

Galvanic Protection: When a zinc rod is connected to an iron pipe, it creates a galvanic cell. Zinc is more reactive than iron, so it acts as the anode, sacrificing itself to protect the iron pipe (cathode). The zinc corrodes instead of the iron, thereby providing protection to the iron surface.Sacrificial Anode: Zinc has a higher electrochemical potential than iron, making it more susceptible to corrosion. This means that zinc will preferentially corrode instead of the iron pipe. By connecting a zinc rod, the zinc sacrificially corrodes, protecting the iron from corrosion. Uniform Protection: Connecting a zinc rod provides uniform protection to the entire iron pipe surface. As long as the zinc rod is in contact with the iron pipe, it will continuously provide cathodic protection along the entire length of the pipe. Extended Protection: The sacrificial zinc anode can provide protection for an extended period before it gets fully consumed. Once the zinc is depleted, it can be replaced with a new zinc rod to continue the protection.

Part 1 The Power of Exponential Growth A scientist places one bacterium in a Petri dish at 9.00 am: The bacteria can reproduce at a rate that doubles its population every minute. At 9.00 there is one, at 9.01 there are two, at 9.03 there are four; etc. The scientist observes that the whole Petri dish is completely full at 10.00 am_ 9.00 am Bacteria 9.01 am 2 Bacteria 9.02 am 4 Bacteria 777 10.00 am Full Quarter Full Half Full When (at what time) was the dish half_ full? What time was it a quarter full? Type your answers here in RED. 2. If they keep growing; how many dishes full of bacteria would you have at 10.022 when a police officer holds the palm of their hands towards you what does that mean For the following equations find 1) the general form for all solutions 2) the solutions on the interval (pi/2)
