2. Air has a heat capacity of 1.007 J/g-K When a certain volume of air is heated from 20°C to 25 Sit requires 11.22J of energy. The density of air is 1.116 x 10-3 g/ml What is the volume of the air heated?
What is the volume of the air heated?

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?
