How does high pressure effect the solubility of a gas?
Damm [24]

Answer:

Gases as might be expected, increase in solubility with an increase in pressure. Henry's Law states that: The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution. ... When the bottle is opened, the pressure above the solution decreases.

Describe Dalton’s atomic theory.
ser-zykov [4K]

Answer:

Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.

Dalton based his theory on the law of conservation of mass and the law of constant composition.

The first part of his theory states that all matter is made of atoms, which are indivisible.

The second part of the theory says all atoms of a given element are identical in mass and properties.

The third part says compounds are combinations of two or more different types of atoms.

The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.

Parts of the theory had to be modified based on the existence of subatomic particles and isotopes

The rate constant for the decomposition of n2o is 2.30 s−1. What is the half-life of the decomposition?
Alchen [17]

Answer:

0.3 s.

Explanation:

Half-life of a first order reaction is defined as the the time taken for any fraction of the reaction to complete is independent of the initial concentration.

Half-life of a first order reaction, t° = 0.693/k

where,

t° = half-life of the reaction

k = rate constant

= 2.3 s^-1

Therefore,

t° = 0.693/2.3

= 0.30 s.
