Nitrogen dioxide and water react to produce nitric acid, HNO3,
and nitrogen oxide.
3NO2(g) + H2O(l) — -→ 2HNO3(aq) + NO(g)
a. How many grams of H20 are required to react with 28.0 g
of NO2?
b. How many grams of NO are produced from 15.8 g of H2O?
c. How many grams of HNO3 are produced from 8.25 g of NOZ?

Answer :

Answer:

Explanation:

a )

3NO₂(g) + H₂O(l) — -→ 2HNO₃(aq) + NO(g)

3 x 46 g       18 g            2 x 63 g       30 g

138 g of NO₂ requires 18 g of H₂O

28 g of NO₂ requires ( 18 / 138) x 28

= 3.65 g of H₂O.

b )

18 g of H₂O produces 30 g of NO gas

15.8 g of H₂O produces ( 30/18 ) x 15.8

= 26.33 g of NO gas .

c )

138 g of NO₂ produces 126 g of HNO₃

8.25 g  of NO₂ produces (126 / 138 ) x 8.25

= 7.53 g of HNO₃
