Question

When nitrogen dioxide (NO2) from car exhaust combines with water in the air, it forms nitric acid (HNO3), which causes acid rain, and nitrogen oxide.Write the balanced chemical equation.How many moles of HNO3 are produced from 0.292 mole of H2O

Answer 1

`n_(HNO_3)=0.584molHNO_3`

Step-by-step explanation:

Hello.

In this case, given the described reaction, the formation of nitric acid turns out:

`NO_2+H_2O\rightarrow HNO_3`

Since two hydrogen atoms are present at the reactants we balance it as follows:

`3NO_2+H_2O\rightarrow 2HNO_3+NO`

In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:

`n_(HNO_3)=0.292molH_2O*(2molHNO_3)/(1molH_2O)\\\\ n_(HNO_3)=0.584molHNO_3`
