When the following equation is balanced, the coefficient of sulfur dioxide is PbS (s) + O 2 (g) PbO (s) + SO 2 (g) 3.

Another component of acid rain is nitric acid, which forms when NO2, also a pollutant, reacts with oxygen and water according to the simplified equation 4NO2 (g) + O2(g) + 2H2O(1) → 4HNO3 (aq) The generation of the electricity used in a medium-sized home produces about 19 kg of NO2 per year. Part A Assuming that there is adequate O, and H2O, what mass of HNO3, in kg, can form from this amount of NO2 pollutant? Express the mass to two significant figures and include the appropriate units. HA ? m = 26.02 %3D

Balance the following chemical reaction, be sure to include “1” in the blank for any compounds with a stoichiometric coefficient of 1.  Fe2O3(s) +  CO(g) →  Fe(l) +  CO2(g)

Chloramine is a toxic gas that can form in swimming pools by the reaction of hypochlorous acid, used to sanitize pool water, with ammonia, a component of sweat and urine. Chloramine gas, NH₂Cl(g), is the cause of the identifiable 'pool smell'. The balanced chemical equation for the reaction of hypochlorous acid and ammonia is: HOCl(aq) + NH₃(aq) → NH₂Cl(g) + H₂O(l) A swimming pool holding 9.50 × 10⁴ gallons of water. 1.00 gallons HOCl sanitizer is enough to sanitize 1.00 × 10⁴ gallons of pool water. The sanitizer has a concentration of 12.00 mg/L of Cl atoms. Determine the moles of chloramine are produced if ammonia is in excess. (1 gal = 3.785 L)
