1. Chemistry

Solid titanium oxide (TiO2) reacts with solid carbon (C) to produce solid titanium (Ti) and gaseous carbon monoxide (CO). When 14.0 kg of C is allowed to react with 44.0 kg of TiO2 7.5 kg of Ti is produced. What is the theoretical yield of Ti expressed in

2. Chemistry

Gasohol contains ethanol (C2H4OH)(l), which when burned reacts with oxygen to produce CO2(g) and H2O(g). How much heat is released when 12.5g of ethanol burns? C2H5OH(l) + 3 O2(g) --> 2 CO2(g) + 3H2O(l) Delta H = -1368kJ How do I solve this problem?
