Multiple Choice
Refer to the balanced chemical equation below. 2 H2 + O2 2 H2O + energy
When this reaction occurs, energy is released explosively in the form of heat and light.Based on this information and your knowledge of chemical reactions, which statement is correct?
A) More energy is stored in two H2 and one O2 than is stored in four O-H bonds.
B) The sum of the energy of two H2 and one O2 is equal to the sum of the energy of four O-H bonds.
C) A water molecule has more stored energy in its bonds than two H2 and one O2 combined.
D) Energy is conserved during this reaction, which means that the chemical bond energies in the products are the same as the chemical bond energies in the reactants.
E) Energy is observed during this reaction because all chemical reactions involve a release of energy; some reactions just release more than others.
