<h3>
Answer:</h3>
Atoms of elements on the reactants side
- 2 Carbon atoms
- 6 Hydrogen atoms
- 7 Oxygen atoms
<h3>
Explanation:</h3>
- The equation; C₂H₅OH+ 3O₂ →2CO₂+ 3H₂O is balanced.
- A balanced chemical equation has an equal number of atoms of each element on either side of the equation.
- For example, in the equation given, the number of atoms of each element is equal on both sides of the equation.
- There are 2 carbon atoms, 6 hydrogen atoms, and 7 hydrogen atoms on either side of the equation.
- According to the law of conservation of mass, the mass of the reactants should be equal to the mass of reactants.
- Therefore, chemical equations are balanced for them to obey the law of conservation of mass.
