If each Hydrogen molecule forms 2e-, then how many kg of H will be required to produce the electricity required for a typical house? Assume about 850 kWh of electricity is used in the home per month, which corresponds to approximately 2.65 * 104 mol of electrons at the voltage of a fuel cell?
if 88.0 ml of H2O is heated from 5°C to 37C then calculate how much heat energy is absorbed?
