Question

using the chemical equation provided, identify which of the following are the coefficients of the reactants. 4fe + 3o₂ → 2fe₂o₃ select all that apply: 7 4 3 2

Explanation:

Step1: Identify reactants

In $4Fe + 3O_2
ightarrow2Fe_2O_3$, reactants are $Fe$ and $O_2$.

Step2: Determine coefficients

Coefficient of $Fe$ is 4 and of $O_2$ is 3. 2 is the coefficient of the product $Fe_2O_3$, and 7 is not a coefficient in this equation.

Answer:

B. 4, C. 3
