The molar mass of AA is 40.0 g/molg/mol , and the molar mass of BB is 60.0 g/molg/mol . What are the lowest whole-number coefficients of AA and BB in the balanced chemical equation? Match the numbers in the left column to the appropriate blanks in the sentences on the right.

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
