Nitrogen dioxide is used industrially to produce nitric acid, but it contributes to acid rain and photochemical smog. what volume of nitrogen dioxide is formed at 724 torr and 28.2° c by reacting 4.84 cm3 of copper (d = 8.95 g/cm3) with 227 ml of nitric acid (d = 1.42 g/cm3, 68.0% hno3 by mass)? cu + 4hno3 = cu(no3)2 + 2no2 + 2h2o
