The balanced chemical equation for the combustion for the complete oxidation of acetylne (C2H2) is given by;
2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g)
<h2>Further Explanation:</h2><h3>Chemical equations </h3>
- Chemical equations are equations showing reactions between reactants to form products.
- Chemical equations show the reactants or starting substances and products or substances formed during the reaction.
For example;2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g)
C2H2 and O2 are the reactants while CO2 and H2O are the products.
<h3>Law of conservation of mass </h3>
- The law of conservation requires that when writing chemical equations, the mass of the reactants should be equal; to the mass of the products.
- This is done by making sure the number of atoms of each element involved in the chemical equation is equal on both sides of the equation.
- To ensure the law of conservation in chemical equations is observed we balance chemical equations.
<h3>Balancing chemical equation:</h3>
- Balancing chemical equations is a try and error method that ensures the number of atoms in the side of the reactants is equal to the number of atoms in the side of products.
- Balancing chemical equations may also require inclusion of state symbols which shows the state of each compound or element involved in the chemical reaction.
2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g)
- It is balanced with; 4 carbon atoms, 10 oxygen atoms, and 4 hydrogen atoms in each side of the equation. Acetylene, oxygen, carbon dioxide and water, all are in gaseous state.
