Question

Choose the statement below that best describes the following chemical equation:

4 Al + 3 O2 --> 2 Al2O3


A. When aluminum reacts with atmospheric oxygen, aluminum oxide is produced
B. The equation demonstrates the law of conservation of mass.
C. The chemical equation is balanced.
D. All statements above describe the chemical equation.

Answer 1

I would say all the statements accurately describe the equation; the union of aluminum plus oxygen, the balanced equation so that what is on the left side also occurs on the right side and also consequently the conservation of mass as a corollary of the preceding.
