1: one gallon of gasoline (c8h18) is combusted in a container with 6.66 m3 oxygen. given: the density of oxygen is 1.43 g / l and the density of gasoline is 0.700 g/ml. find the mass of the reactant in excess. ( 1gallon = 3.7854 l and 1m3 = 1000 l)

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

What is the most useful equation for electric power?

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
