Problem 39P

PROBLEM 39P

Hydrogen has been proposed as a alternative fuel to replace fossil fuels. Some scientists are trying to anticipate any potential problems that might be associated with a hydrogen-based economy. One group of scientists has calculated that the amount of atmospheric hydrogen could increase by a factor of four due to leaks in hydrogen transport and storage. Upper atmospheric hydrogen gas reacts with oxygen gas to form liquid water. An increase in upper atmospheric water would enhance processes that release atmospheric chlorine atoms. The gaseous chlorine atoms would then react with gaseous ozone (O3) to form gaseous chlorine monoxide and gaseous oxygen, resulting in the depletion of ozone. Write balanced chemical equations for the two reactions described in this problem.

Step-by-Step Solution:
Step 1 of 3

Solution 39P

Here, we have to write the balanced chemical equation for each reaction.

According to the question,

Upper atmospheric hydrogen gas reacts with oxygen gas to form liquid water. Therefore, balanced chemical equation of the reaction is given below.

2H2(g) +O2(g)------> 2H2O(l)

Secondly, an increase in upper atmospheric water would enhance processes that release atmospheric chlorine atoms. The gaseous chlorine atoms would then react with gaseous ozone (O3) to form gaseous chlorine monoxide and gaseous oxygen, resulting in the depletion of ozone.Therefore, balanced chemical equation of the reaction is given below.

Cl2(g) +4O3(g) ---------> 2ClO(g) +5O2(g)
