Calculate the quantity of heat required to raise the temperature of 10g of ice from −100C to 1100C.
Answer this Question
Heat of Formation
When 10.00 g of iron is burned in O2(g)to form Fe3O4 (s) , enough heat is generated to raise the temperature of 784 g of water from 18.0 C to 38.0 C. Calculate the heat of formation of Fe3O4 (s) under these conditions in kJ/mol.
