What is a balanced chemical reaction?

Answer 1

In a balanced chemical equation there should be the same amount of atoms present in the products as there were in the reactants and only whole molecules can be formed or used (no half molecules). For example... CH4 + 2O2 = Co2 + 2H2O. If you add up the various atoms in the reactants you find 1 x Carbon, 4 x Hydrogen and 4 x Oxygen. The products contain 1 x Carbon, 4 x Hydrogen and 4 x Oxygen. The equation is therefore balanced. You will note also that 2 molecules of O2 were used as reactants in order to produce complete molecules of products.

Answer 2

A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide.

Unbalanced chemical equation:

Mg(s) + O2(g) --> MgO(s)

Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction.

Balanced chemical equation:

2Mg(s) + O2(g) --> 2MgO(s)

This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.

Answer 3

A balanced chemical reaction is one where the number of each type of atom is the same on both sides of the reaction equation. This means that the law of conservation of mass is obeyed, as no atoms are created or destroyed during the reaction. Balancing is done by adjusting the coefficients in front of each compound in the reaction equation.

Answer 4

A balanced chemical equation describes the chemical nature of the reactants and products and the amount of each reactant used or product formed.

Answer 5

when the reactants equal the substrate exp H2+O= H2O

Answer 6

Chemical Bonds

Its mole ratios not chemical bonds

Answer 7

Balanced Chemical Equation is an equation in which the number of moles of reactant is equal to the moles of product .
