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?

How much heat, in joules, is necessary to raise the temperature of a 3.5g piece of aluminum from 22 degrees C to 37 degrees C? (J/g*C = 4.18 ; cal/g*c = 1.00)

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...
