If hydrogen were used as a fuel, it could be burned according to the following reaction:
H2(g) + 1/2O2(g) > H2O(g).
A) Use average bond energies to calculate ΔHrxn for this reaction.

Based on the position vs. time graph which velocity vs. time graph would correspond to the data

You just calculated that the heat of fusion for chloromethane is 6400 j/mol. the heat of fusion for hydrogen is 120 j/mol.? which of the following account for this difference? more than one correcta. chloromethane can absorb more energy at the same temperature. b. hydrogen has stronger intermolecular forces than chloromethane. c. hydrogen molecules can pack more closely than chloromethane molecules. d. chloromethane experiences dipole-dipole interactions. e. chloromethane has a higher molar mass than hydrogen.

Na chemical reaction, activation energy increases the of the reactants. this outcome causes the particles to collide, which results in the of new products.
