which option shows a coefficient on the product side in this chemical equation?
3Fe +4H20 -->Fe30 +4H2
A. the 3 in Fe and 4 in H2O
B.the 2 in H2O the 3 and 4 in Fe3o4 and the 2 in H2
C.the 4 in H2
D.the 3 in Fe and 4 in H2O and 4 in H2
C.the 4 in H2
The coefficient in a chemical equation refers to the number written in front of a chemical formula, indicating the number of molecules or atoms involved in the reaction. To identify the coefficient on the product side of the equation, we need to look at the substances that are produced.
The given chemical equation is:
3Fe + 4H2O → Fe3O4 + 4H2
In this equation, the product side consists of Fe3O4 and H2. To identify the coefficients on the product side, we can look at the numbers written in front of these formulas.
Option A includes the 3 in Fe and 4 in H2O, which are on the reactant side rather than the product side. Option B includes the 3 and 4 in Fe3O4 and the 2 in H2, but only the 4 in H2 is a coefficient on the product side.
Therefore, the correct answer is C. The 4 in H2 is the coefficient on the product side in this chemical equation.
