Why is it possible to collect hydrogen gas over water?
maw [93]
A gas produced in a chemical reaction can be collected by water displacement. Because the gas is collected over water, it is not pure but is mixed with vapor from the evaporation of the water. Dalton's law can be used to calculate the amount of the desired gas by subtracting the contribution of the water vapor.

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.
