Look at the following balanced equation. How many atoms of oxygen (O) are present on the reactant side of the equation?

balu736 [363]

There are 6 atoms of oxygen on the reactant side of the following equation: 2Fe2O3 + 3C → 4Fe + 3CO2. Details about atoms can be found below.

<h3>How to find number of atoms?</h3>

The number of atoms of an element in a balanced equation is the amount of that element involved in the reaction.

According to this question, Iron oxide reacts with carbon to produce iron and carbon dioxide as follows:

2Fe2O3 + 3C → 4Fe + 3CO2

In this reaction, 2 × 3 atoms = 6 atoms of oxygen are present on the reactant side of the equation.

0.68 moles of calcium to calcium atoms

Oksanka [162]

$0.68 \: moles \: calcium \times \frac{6.02 \times {10}^{23} \: calcium \: atoms }{1 \: mole \: calcium} \\$

The (( mole calcium ))s are simplified so the answer is based on the number of calcium atoms.

$0.68 \times 6.02 \times {10}^{23} = 68 \times {10}^{ - 2} \times 602 \times {10}^{ - 2} \times {10}^{23} \\$

$= 68 \times 602 \times {10}^{ - 4} \times {10}^{23} = 40936 \times {10}^{19} \\$

$calcium \: atoms = 40936 \times {10}^{19} \\$
