Which of the following statements is correct about the reaction given below:-
`4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`

Options

A. Total mass of iron and oxygen in reactant =total mass of iron and oxygen in product tehrefore it follows law of conservation of mass
B. Total mass of reactants =total mass of product, therefore, law of multiple proportions is followed
C. Amount of `Fe_(2)O_(3)` can be increased by taking any one of the reactants (iron or oxygen) in excess.
D. Amount of `Fe_(2)O_(3)` produced will decrease if the amount of any one of the reactants (iron or oxygen) is taken in excess

Explanation

To determine which statement is correct about the reaction \( 4Fe(s) + 3O_2(g) \rightarrow 2Fe_2O_3(g) \), let's analyze each option step by step.

### Step 1: Analyze the Reaction
The given reaction involves the combination of iron (Fe) and oxygen (O2) to form iron(III) oxide (Fe2O3).

### Step 2: Check the Law of Conservation of Mass
According to the law of conservation of mass, the total mass of reactants must equal the total mass of products.
