Write a balanced equation for the complete oxidation reaction that occurs when acetylene (c2h2) burns in air. use the smallest possible integer coefficients.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products must be same as the mass of reactants.

For the conservation of mass, the number of atoms of each element must be same in reactants and products. Thus we need to balance the reaction by writing appropriate stochiometric coefficients.

Thy hydrocarbons such as acetylene [tex](C_2H_2)[/tex] burn in oxygen to form carbon dioxide and water.

[tex]2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O[/tex]

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)

Further Explanation:

Chemical equations

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.

Law of conservation of mass

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.

Balancing chemical equation:

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.

In the 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.
