Alvin is heating a solution in his chemistry lab. The temperature of the solution is at 14°C. He turns on the burner and finds that the solutions temperature increases 2°C every minute. This graph shows the temperature change.

Nitrogen dioxide reacts with water to form nitric acid and nitrogen monoxide according to the equation: 3no2(g)+h2o(l)→2hno3(l)+no(g) part a suppose that 4.2 mol no2 and 0.50 mol h2o combine and react completely. which reactant is in excess? express your answer as a chemical formula. nothing
