The two balanced equations (1) and (2) are for reactions in which gaseous carbon dioxide is produced from the combustion of (1) solid carbon and (2) gaseous carbon monoxide.

1. c(s) + o2(g) co2(g) + 94.0 kcal

2. co(g) + ½o2(g) co2(g) + 67.6 kcal

when 112 grams of carbon monoxide are consumed according to equation (2), which of the following occurs? (atomic weights: c = 12.0 g/mol, o = 16.0 g/mol)

1.0 mole of carbon dioxide is produced.
67.6 kcal of heat are generated.
2.00 moles of oxygen are consumed.
0.25 mole of carbon dioxide is produced.
0.50 mole of oxygen is consumed.
