When oxygen combines with hydrogen in the reaction 1580, Ask an Expert

Engineering

When oxygen combines with hydrogen in the reaction (15.80) about 5eV of energy is released (that is, the kinetic energy of the two final molecules is 5 eV more than that of the initial three molecules).

(a) By how much does the total rest mass of the molecules change?

(b) What is the fractional change in total mass? (c) If one were to form 10 grams of water by this reaction, what would be the total change in mass?
