The balanced equation for the combustion of ethene is given below. If 97.7 g of oxygen is used, how much heat energy will be produced? C2H4 + 3O2 2CO2 + 2H2O + 1390 kJ​

Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reactants. consider 1 mole of tritium plus 1 mole of deuterium to be a mole of “reactions” (total molar mass = 5 grams).

Motivation cannot be developed with practice; a person either possesses it or they do not.

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night.  when he took it out, its new volume was 322 milliliters, but its pressure was the same.  if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is  kelvins.
