quiz
question 7 of 10
in the early 20th century, scientists discovered atmospheric nitrogen could be used to create ______.
choose one option
a nitrous oxide
b nickel nitrate
c nitrous acid
d nitric acid

Explanation:

In the early 20th century, the Haber - Bosch process was developed to fix atmospheric nitrogen into ammonia, and subsequent processes can be used to produce nitric acid ($\ce{HNO_3}$) from ammonia. Nitrous oxide ($\ce{N_2O}$) is not typically produced from atmospheric nitrogen for large - scale industrial purposes in this context. Nickel nitrate ($\ce{Ni(NO_3)_2}$) involves nickel and is not a direct product from atmospheric nitrogen for the main industrial use of nitrogen fixation in the early 20th century. Nitrous acid ($\ce{HNO_2}$) is not the main product from atmospheric nitrogen fixation and subsequent industrial processes. So the correct option is D as atmospheric nitrogen can be used to create nitric acid.

Answer:

D. nitric acid
