Based on the potential energy diagram and the potential energies of reactant and product the synthesis and double replacement reactions are endothermic. The single replacement reaction is exothermic and the ΔH is negative.

Chemical processes referred to as endothermic reactions occur when the reactants take in heat energy from their environment to create products. The reaction absorbs energy from its surroundings. The energy that manifests as heat. Examples include cooking, evaporation, gas molecules, melting of ice, and photosynthesis.

An exothermic reaction is one in which energy is given off as heat or light. The mechanism releases energy into its surroundings. Energy can be emitted as sound, light, heat, or electricity. Examples include rusting iron, settling, chemical bonds, explosions, and nuclear fission.

A potential energy diagram, also known as a reaction progress curve, is a visual representation of the energy changes that take place during a chemical reaction. A diagram of potential energy illustrates how a system's potential energy changes as reactants are changed into products. Note that an exothermic reaction results in a negative enthalpy change while an endothermic reaction exhibits a positive enthalpy change. The diagrams of potential energy show this. When the system absorbs energy from its environment, its overall potential energy rises for the endothermic reaction. As the system undergoes the exothermic process, the system's overall potential energy declines.

Explanation:

Solid ice has a specific heat capacity that is different from that of liquid water. The value of that is not given here, so we will assume that "liquid ice" has the same specific heat as liquid water.

The heat liberated by cooling 14 g of water from 30°C to -20°C is ...

  (4.184 J)/(g·K)×(14 g)×(30-(-20))K = 2928.8 J

The mass 14 g of water in moles is ...

  (14 g)/(18.01528 g/mol) ≈ 0.77712 mol

The heat of fusion (converting liquid water to "liquid ice") is then ...

  (6.008 kJ)/mol × 0.77712 mol = 4668.9 J

Answer:

Q < Ksp

Explanation:

The general equilibrium of a constant product solubility, ksp, is:

AB ⇄ A⁺ + B⁻

Where Ksp is defined as:

Ksp = [A⁺] [B⁻]

When [A⁺] [B⁻] = Ksp, the solution is saturated or oversaturated because there are the maximum amount of ions that solution can dissolve.

When the solution is oversaturated, AB is produced.

Now, in a unsaturated solution, the [A⁺] [B⁻] is less than the maximum amount that can be dissolved. That means:

[A⁺] [B⁻] = Q < Ksp

Q is defined in the same way than Ksp, just in Q the system is not in equilibrium.

Right answer is:

The  mathematical relationship for an unsaturated solution in comparing Q with K sp is Q < Ksp.

Since

The general equilibrium of a constant product solubility, ksp, should be

AB ⇄ A⁺ + B⁻

Here. Ksp is defined as:

Ksp = [A⁺] [B⁻]

At the time When [A⁺] [B⁻] = Ksp, the solution should be saturated or oversaturated since there are the maximum amount of ions that solution can dissolve.

When the solution is oversaturated, AB is produced.

Now, in a unsaturated solution, the [A⁺] [B⁻] is lower than the maximum amount that can be dissolved. That means [A⁺] [B⁻] = Q < Ksp

Answer:

0.648 g

Explanation:

Step 1: Write the balanced equation

2 Na(s) + 2 H₂O(l) ⇒ 2 NaOH(aq) + H₂(g)

Step 2: Calculate the partial pressure of H₂

The total pressure (P) is equal to the sum of the partial pressures of hydrogen and water vapor.

P = pH₂O + pH₂

pH₂ = P - pH₂O

pH₂ = 759 mmHg - 23.8 mmHg = 735 mmHg

Step 3: Convert "pH₂" to atm

We will use the conversion factor 1 atm = 760 mmHg.

735 mmHg × 1 atm/760 mmHg = 0.967 atm

Step 4: Convert "25°C" to K

We will use the following expression.

K = °C + 273.15 = 25°C + 273.15 = 298 K

Step 5: Calculate the moles of hydrogen (n) formed

We will use the ideal gas equation.

P × V = n × R × T

n = P × V/R × T

n = 0.967 atm × 8.11 L/(0.0821 atm.L/mol.K) × 298 K = 0.321 mol

Step 6: Calculate the mass corresponding to 0.321 moles of hydrogen

The molar mass of H₂ is 2.02 g/mol.

0.321 mol × 2.02 g/mol = 0.648 g

Answer:

Hubble's law says that the universe is expanding outward.

Explanation:

Actually Hubble's law was discovered before the Big Bang theory was formulated. The Big Bang Theory is an attempt to explain the observations that led to Hubble's Law.Before the 1900s the theory was that the universe was eternal and self existent. The idea was that the universe was in a steady state having always existed and would always continue to exist. Albert Einstein even changed the equations in his general theory of relativity to reflect the idea of a steady state. Later he called putting in a fudge factor to result in a steady state the worse mistake of his life.

Hubble observed that most of the universe has a red shift indicating that the universe is expanding and moving away from itself. The further out that the universe is observed the faster it is moving apart.

These observations were inconsistent with a steady state universe.

The Big Bang theory extrapolated backwards. If the universe is expanding and spreading out from itself then further back in time the universe was closer together. The Theory explained Hubble's observations by the idea that at the beginning of time ( for our universe) all the matter and energy were together in one place.

This super dense ball of matter and energy then exploded outwards creating space and time as it is presently observed. The question was would the forces of gravity and black holes bring the matter and energy back together again. The answer found in 1998 was no. The rate of the expansion of the universe is increasing not slowing down and the universe will not collapse back into the super dense ball of matter that it began as.

The Big Bang Theory postulated based on the empirical evidence that our universe had a beginning and it will eventually cease to exist. The conclusion based on Hubble's observations is that matter and energy are not eternal and self existent.

The identity of a cation solution that produces a mix of red and yellow colors in a flame test, but appears red when viewed through a cobalt filter, can be attributed to the presence of the strontium (Sr) cation.

During a flame test, different metal cations emit characteristic colors due to the excitation of electrons and their subsequent emission of light. Strontium, in particular, is known to produce a vibrant red color in flame tests.

The presence of both red and yellow colors indicates the possibility of multiple metal cations in the solution. While the specific metal responsible for the yellow color is uncertain, it could potentially be sodium or another metal that emits a yellow flame.

When the flame is viewed through a cobalt filter, which absorbs yellow wavelengths of light, the yellow color is filtered out, resulting in only the red color being observed. Since strontium is known for its distinctive red flame color and its emission is not affected by the cobalt filter, it is likely the metal cation responsible for the observed red color. Therefore, based on these characteristics, the identity of the cation solution is most likely strontium (Sr).

Basic chemistry

According to the claim, Balloon A, which has more blue and less orange, exhibits accurate effusion at a relative effusion rate of 1.303. (orange is 1.303 times more effused than blue).Relative rate of effusion for the orange to blue spheres = 1.531.

The process of effusion is when a gas escapes from a container through a hole that is significantly smaller in diameter than the molecules' mean free path.

Gas molecules flow through a small opening in one container and into another by effusion. Graham's law allows rates of effusion to be compared at the same temperature. Diffusion is the random molecular motion-based movement of gas molecules through one or more other types of gas.

Rate of effusion of Orange / Rate of effusion of blue

= [Mblue / Morange]^1/2

Vrms = sqrt [(3RT/M)]

Vorange / Vblue = [ Mblue / Morange]^1/2

Rate of effusion of Orange / Rate of effusion of blue

= 565/ 369

= 1.531

Thus,  Balloon A, which has more blue and less orange, exhibits accurate effusion at a relative effusion rate of 1.303.

Explanation:

1.17×10^24 molecules of co2

According to the engineer's design, 14.67 moles of N2 would be produced in the reaction.

To determine the amount of N2 that would be produced according to the engineer's design, we need to understand the stoichiometry of the reaction between dinitrogen tetroxide (N2O4) and hydrazine (N2H4).

The balanced chemical equation for the reaction is:

N2H4 + N2O4 → N2 + 2H2O

From the balanced equation, we can see that one mole of N2H4 reacts with one mole of N2O4 to produce one mole of N2. Therefore, the mole ratio between N2H4 and N2 is 1:1.

Given that the engineer designed the rocket to hold 1.35 kg of N2O4, we need to convert this mass to moles using the molar mass of N2O4. The molar mass of N2O4 is approximately 92.01 g/mol.

Moles of N2O4 = Mass of N2O4 / Molar mass of N2O4

= 1.35 kg / 92.01 g/mol

= 14.67 mol

Since the mole ratio between N2H4 and N2 is 1:1, the number of moles of N2 produced would be the same as the number of moles of N2O4, which is 14.67 mol.

Answer:

A. The reaction shifts to the right (products) and the concentrations of I and H₂ decrease.

Explanation:

If gas is removed from the system at equilibrium, the system will try to compensate for the loss by shifting the reaction in a direction that produces more gas molecules. This is known as Le Chatelier's principle, which states that a system at equilibrium will respond to a disturbance by shifting in a way that minimizes the effect of the disturbance.

In this case, since gas is being removed from the system, the reaction will shift to the side that produces more gas molecules. Looking at the balanced equation, we can see that 2HI(g) has a greater number of gas molecules compared to H₂(g) and I₂(g). Therefore, the system will shift to the right (products) to produce more HI(g) and reestablish equilibrium.

A 1 L sample of CO initially at STP is heated to 546 K, and its volume is increased to 2 L, the final pressure of CO is 1 atm.

We have,

Initial volume, V₁ = 1 L

Final volume, V₂ = 2 L

Initial temperature, T₁ = 273 K (standard temperature)

Final temperature, T₂ = 546 K

Initial pressure, P₁ = 1 atm

Final pressure, P₂ = ?

To calculate final pressure, we will use combined gas law.

Combined gas law is given as -

                                               P₁V₁ = P₂V₂

                                                 T₁        T₂

where,

P₁ = initial pressure

P₂ = final pressure

V₁ = initial volume

V₂ = final volume

T₁ = initial temperature

T₂ = final temperature

Substituting values in the gas law equation -

1 x 1 = P₂ x 2

273       546

P₂ = 546 x 1 x 1  atm

          273 x 2

P₂ = 1 atm
