4. Carbon dioxide gas, CO (g), produced in the combustion of a sample of ethane is absorbed in Ba(OH)2 (aq), producing 0.506 g BaCO3 (s). How many grams of ethane (CH6) must have been burned? (unbalanced reaction) C2H6 (g) + O2 (g) CO2 (g) + HO (1) CO (g) + Ba(OH)2 (aq) BaCO3 (s) + H0 (1)

4. Carbon dioxide gas, CO2(g), produced in the combustion of a sample of ethane is absorbed in Ba(OH)2(aq), producing 0.506gBaCO3(s). How many grams of ethane (C2H6) must have been burned? C2H6(g)+O2(g)CO2(g)+H2O(l)CO2(g)+Ba(OH)2(aq)BaCO3(s)+H2O(l) (unbalanced reaction)
