question 93

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.
