Methanol (CH3OH) burns according to the equation 2CH3OH(l) + 3O2(g)  2CO2(g) + 4H2O(l), H°rxn = –1454 kJ/mol. How much heat, in kilojoules, is given off when 75.0 g of methanol is burned? A)727 kJD)1.70  103 kJ B)3.22  103 kJE)3.41  103 kJ C)1.45  103 kJ

What changes occur in the reaction indicated by the equation? check all that apply. the hydrogen nucleus loses protons. the oxygen nucleus gains protons. the bond in h2 is broken, and new bonds are formed between hydrogen and oxygen atoms. each electron associated with a hydrogen atom is shared with an oxygen atom.
