For many purposes we can treat propane
dangina [55]

Answer:The volume increases by 11%

Explanation:

When the pressure is decreased, the volume must definitely increase, to maintain the same pressure, the temperature must then also be increased as we see in the question. The volume was increased just as the pressure decreased and the temperature had to be increased to maintain a constant pressure. We have applied the general gas equation in solving the problem.

No amino acid molecule by itself can speed up or catalyze reactions between other molecules; however, when amino acids are joine
Nadya [2.5K]

Answer:

That the enzyme is a protein

Explanation:

Remember the proteins are groups of thousands of amino acids, by their owns, since they are very small units, they can not act as a catalyst.

But as a polymer, the protein enzyme, have different shape, size and physical and chemical properties than a single monomer.

Remember also the proteins to be active, they need certain number of amino acids join together to form a specific shape that is going to match with another molecule to speed the chemical reaction and act as an enzyme.

Which statement correctly describes a sample of gas confined in a sealed container? (1) It always has a definite volume, and it
Luda [366]
A gas does not have a specific shape or volume (so we reject option A), instead it adjusts itself to the container (which is further influenced by other forces such as gravity and temperature) and it with time, willl fill the whole container evenly, so the correct answer is:
(2) It takes the shape and the volume of any container in which it is confined

What is the thermal energy needed to vaporize 18.02g of water at 100°C? The Heat of Vaporization for water is 40.650 kJ/mol.
podryga [215]

Answer:

40.7 kJ

Explanation:

Applying,

q = c'n.................. Equation 1

Where q = Thermal Heat, c' = Heat of vaporization of water, n = number of mole of water.

But,

n = mass(m)/Molar mass(m')

n = m/m'............... Equation 2

Substitute equation 2 into equation 1

q = c'(m/m')............. Equation 3

Given: c' = 40.650 KJ/mol, m = 18.02 g

Constant: m' = 18 g/mol

Substitute into equation 3

q = 40.650(18.02/18)

q = 40.695 kJ

q ≈ 40.7 kJ
