5 sg / 3 sg

Explanation:

The change in energy of a mixture of gaseous reactants during a chemical reaction indicates that the reaction is exothermic. Additionally, the negative work done on the mixture suggests that the volume of the system decreases during the reaction.

The increase in energy of the gaseous reactants indicates that the reaction releases energy to the surroundings, which is characteristic of an exothermic reaction. In an exothermic reaction, the products have lower energy than the reactants, resulting in a decrease in the total energy of the system. The negative work done on the mixture suggests that the reaction causes a decrease in volume.

This can occur when the total number of moles of gaseous reactants is greater than the total number of moles of gaseous products, leading to a decrease in volume as the reaction proceeds. The negative work done indicates that the system is doing work on the surroundings, resulting in a decrease in volume.

The variable part of an amino acid is the e. side chain.

The variable part of an amino acid is known as the side chain or R-group. Amino acids are the building blocks of proteins, and each amino acid consists of a central carbon atom (alpha carbon) bonded to four groups: an amino group (NH2), a carboxyl group (COOH), a hydrogen atom (H), and the side chain.

The side chain is responsible for the unique properties of each amino acid and determines its chemical behavior and interactions within a protein structure.

The side chain plays a crucial role in determining the protein's structure, function, and interactions with other molecules. It can be hydrophilic (water-loving), hydrophobic (water-repellent), or charged, and these characteristics influence how the amino acid interacts with its environment. The side chain's size, shape, and chemical properties dictate the folding and stability of the protein, as well as its ability to interact with other proteins, nucleic acids, or small molecules. Therefore, understanding the side chain's nature is fundamental to comprehending the complex structures and functions of proteins.

Answer:

  liquid

Explanation:

If there are no s-waves, the interior must be liquid, where s-waves cannot travel.

There can be six electrons since we are dealing with a 4p orbital, the 4p orbital and we do have three orbitals that make up the four p level.

The 4p orbital can hold a maximum of 6 electrons. Each orbital can accommodate a maximum of 2 electrons with opposite spins, and the 4p subshell consists of three 4p orbitals (4px, 4py, and 4pz), each of which can hold up to 2 electrons, resulting in a total of 6 electrons.

Thus since we know that the n = 4, ml = 1 is the 4p orbital and we do have three orbitals that make up the four p level, they will each hold two electrons.

The mass of LiOH needed to make a 300 mL of a solution with a pH of 11.33 is 0.015 g

We'll begin by calculating the pOH of the solution.

pH = 11.33

pOH =?

pH + pOH = 14

11.33 + pOH = 14

Collect like terms

pOH = 14 – 11.33

pOH = 2.67

pOH = –Log [OH⁻]

2.67 = –Log [OH⁻]

–2.67 = Log [OH⁻]

Take the as antilog of –2.67

[OH⁻] = antilog (–2.67)

LiOH(aq) —> Li⁺(aq) + OH⁻(aq)

From the balanced equation above,

1 mole of LiOH contains 1 mole of OH⁻

Therefore,

0.0021 M LiOH will also contain 0.0021 M OH⁻.

Molarity of LiOH = 0.0021 M

Volume = 300 mL = 300 / 1000 = 0.3 L

Mole = Molarity × volume

Mole of LiOH = 0.0021 × 0.3

Mole of LiOH = 0.00063 mole

Molar mass of LiOH = 7 + 16 + 1 = 24 g/mol

The maximum mass of carbon dioxide that could be produced by the chemical reaction is 0.880 g.

The maximum mass of carbon dioxide that could be produced by the chemical reaction between gaseous butane (C4H10) and gaseous oxygen (O2) can be calculated based on the given masses of butane and oxygen.

The balanced chemical equation for the reaction is:

2 C4H10 + 13 O2 → 8 CO2 + 10 H2O

Using the molar masses of butane (58.12 g/mol) and carbon dioxide (44.01 g/mol), we can calculate the maximum mass of carbon dioxide produced.

First, we need to determine the limiting reactant, which is the reactant that is completely consumed and determines the maximum amount of product formed. To do this, we compare the moles of butane and oxygen.

Moles of butane = 0.581 g / 58.12 g/mol = 0.01 mol

Moles of oxygen = 1.1 g / 32.00 g/mol = 0.034 mol

Since the stoichiometric ratio of butane to oxygen is 2:13, we can see that there is an excess of oxygen. Therefore, oxygen is the limiting reactant.

Next, we calculate the moles of carbon dioxide produced using the mole ratio from the balanced equation: 8 moles of CO2 are produced per 13 moles of O2.

Moles of CO2 = (0.034 mol O2) × (8 mol CO2 / 13 mol O2) = 0.020 mol CO2

Finally, we calculate the mass of carbon dioxide using the molar mass:

Mass of CO2 = (0.020 mol CO2) × (44.01 g/mol) = 0.880 g

Therefore, the maximum mass of carbon dioxide that could be produced by the chemical reaction is 0.880 g.

The major difference between heat transfer by conduction and convection and heat transfer by radiation is that heat transfer by conduction and radiation requires a material medium, while heat transfer by radiation is done by electromagnetic waves and doesn't require a medium.

Heat or thermal energy is the energy generated when atoms or molecules move in a variety of directions (translational, rotational and vibrational). The three methods of heat transfer are convection, conduction and radiation. Conduction only occurs between solid objects in contact, convection occurs within a fluid, and radiation occurs through electromagnetic waves.

Unlike conduction and convection, radiation doesn't require a material medium before heat is transferred, as electromagnetic radiations don't require a material medium to propagate. Heat is transferred by radiation through infrared rays. Other differences include:

The spontaneity of a reaction is determined by the Gibbs free energy change (∆G), which is a measure of the system's ability to do work.

The equation that links ∆G, ∆H, and ∆S is: ∆G = ∆H - T∆S, where T is the temperature in Kelvin and ∆H and ∆S are the enthalpy and entropy changes, respectively. The signs of ∆H and ∆S determine whether the reaction is exothermic or endothermic and whether it is entropy-driven or enthalpy-driven, respectively.

If ∆G is negative, the reaction is spontaneous, meaning it occurs without the input of energy.The given reaction has a ∆H of 23.25 kJ and a ∆S of 161.26 J/mol∙K.

First, we need to convert the units of ∆S from J/mol∙K to kJ/mol∙K by dividing by 1000.∆S = 161.26 J/mol∙K ÷ 1000 = 0.16126 kJ/mol∙K Substitute the values into the equation to determine the spontaneity of the reaction:

∆G = ∆H - T∆S∆G = (23.25 kJ) - (298 K) x (0.16126 kJ/mol∙K)∆G = 23.25 kJ - 48.02 kJ∆G = -24.77 kJ Since ∆G is negative, the reaction is spontaneous.

The mass of aluminum that reacted to produce this quantity of hydrogen gas is 0.181 g.

Partial pressure is a term used in chemistry and physics to describe the pressure that a single gas component would exert if it occupied the same volume as a mixture of gases. In a mixture of gases, each gas exerts a pressure known as its partial pressure, which is proportional to the number of molecules of that gas in the mixture.

To calculate the partial pressure of hydrogen gas in the sample, we can use the following equation:

Partial pressure of hydrogen gas = Total pressure - Vapor pressure of water

Partial pressure of hydrogen gas = 129 kPa - 4.10 kPa = 124.90 kPa

Therefore, the partial pressure of hydrogen gas in the sample is 124.90 kPa.

To calculate the mass of aluminum that reacted to produce this quantity of hydrogen gas, we need to use the balanced chemical equation for the reaction and the ideal gas law. The balanced chemical equation for the reaction of aluminium with hydrochloric acid is as follows:

2Al + 6HCl = 2AlCl3 + 3H2

From the equation, we see that two moles of aluminum react to produce three moles of hydrogen gas. We can use the ideal gas law to calculate the number of moles of hydrogen gas in the sample:

PV = nRT

n = PV/RT

where P is the partial pressure of hydrogen gas, V is the volume of gas collected, R is the gas constant, and T is the temperature in kelvin.

First, we need to convert the temperature from Celsius to kelvin:

T = 29.4 + 273.15 = 302.55 K

Next, we can calculate the number of moles of hydrogen gas:

n = (124.90 kPa)(206.1 mL)/(8.31 L·kPa/mol·K)(302.55 K)

n = 0.0101 moles

Since two moles of aluminum react to produce three moles of hydrogen gas, the number of moles of aluminum that reacted is:

n(Al) = (2/3)n(H2) = (2/3)(0.0101 moles) = 0.00673 moles

Finally, we can use the molar mass of aluminum to calculate the mass of aluminum that reacted:

mass(Al) = n(Al) × molar mass(Al)

mass(Al) = 0.00673 moles × 26.98 g/mol = 0.181 g

Cations are always smaller than the atoms from which they form. Anions are always larger than the atoms from which they form. Ions are usually bigger than the atoms from which they are formed.

When an atom receives or loses electrons, the atom's electron configuration changes, resulting in a net positive or negative charge.

This net charge expands the electron cloud surrounding the nucleus, making the ion bigger in size than the neutral atoms from which it arose. When a metal atom loses one or more electrons to create a cation, it shrinks in size because the positive charge of the nucleus pulls the remaining electrons more strongly.

When a nonmetal atom obtains one or more electrons to create an anion, it normally expands in size.Because of the increasing amount of electrons, the electron cloud surrounding the nucleus grows. It should be noted that this comparison is not absolute and is dependent on the individual factors involved. Some ions are smaller than their neutral atom counterparts, while others are similar in size.

The statement that is true of the solubility of a gas in a liquid is that "the solubility of the gas in the liquid usually increases as pressure increases".

The solubility of a gas in a liquid is the amount of gas that dissolves in a given volume of a liquid at a particular temperature and pressure. The solubility of a gas in a liquid is affected by changes in temperature, pressure, and the nature of the solvent and the solute. The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas over the liquid.

Therefore, if the partial pressure of the gas above the liquid is increased, the solubility of the gas in the liquid also increases. If the partial pressure of the gas above the liquid is decreased, the solubility of the gas in the liquid also decreases. This phenomenon is known as Henry's law.

According to Henry's law, the solubility of a gas in a liquid is directly proportional to the pressure of the system. Therefore, as the pressure of the system increases, the solubility of the gas in the liquid decreases. Conversely, as the pressure of the system decreases, the solubility of the gas in the liquid increases.

To summarize, the solubility of a gas in a liquid usually increases as pressure increases. This is because the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas over the liquid.

During an asthma attack temperature can be decreased to increase the volume of the airway.

This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume.

\(\rm \dfrac{V'}{T'} = \dfrac{V}{T}\)

which means volume is inversely proportional to temperature so the temperature can be decreased in the atmosphere to increase volume of the airway.

This means that, when you inhale cold air, it will change volume as it warms in passing through the sinuses.

As the air warms it expands to a larger volume.

Therefore during an asthma attack temperature can be decreased to increase the volume of the airway.
