The information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction is the number appearing immediately before the formula for the reactant in question in the chemical equation. This number is called a "coefficient".

What is a balances chemical equation?

A balanced chemical equation demonstrates the law of conservation of mass, which requires the same number of atoms of each element to appear both sides of a chemical equation. A coefficient is a number that is placed in front of a chemical formula in a balanced equation to show how many units of the substance are involved in the reaction. It is very important to remember that the only way to balance a chemical equation is to add coefficients.

What does a balanced chemical equation convey to a chemist?

A balanced equation indicates the chemical formulas for the substances involved in the reaction and the number of molecules or moles of each substance in the reaction. This enables a chemist to calculate the amount of each reactant needed to produce a desired quantity of product.


What do you mean by a balanced chemical equation?

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.


What number describes how many molecules are involved in a chemical reaction?

In a balanced equation for the reaction, the coefficient appearing immediately before the formula for a reactant describes the number of moles of that reactant involved in the reaction shown by the equation.


When is the principle of a conservation of a mass number satisfied in a chemical equation?

When the equation is "balanced", that is, when the number of each kind of atoms involved in the reaction is the same in both the total reactants and the total products.

When you balance equation what is it showing?

A balanced equation is representative for the amounts and nature for reactants and products involved.


What information can be obtained from a chemical equation?

- indications about reactants and products (chemical formula etc.) - quantities of chemicals involved in the reaction - type of reaction


Why must chemical equations always balance?

Balancing Chemical Equations is absolutely essential if you want to determine quantities of reactants or products. An unbalanced chemical equation gives only the identify of the beginning reactants and the final products using the appropriate formulas as well as the conditions of temperature, physical state, and pressure conditions under which the reaction is to operate under. However an unbalanced equation can say nothing about the quantities involved until the equation has been balanced. A balanced equation assures that the conservation law of matter is obeyed. The total mass of reactants must equal the total mass of products. A balanced equation tells you the proportional quantities of each substance involved.


How do you summarize the information represented in a chemical equation?

- indications about reactants and products (chemical formula etc.) - quantities of chemicals involved in the reaction - type of reaction


What information in a balanced chemical equation shows how many moles of a reactant are involved in the reaction?

The coefficient (not a subscript or superscript) placed immediately before the formula of the reactant in the equation shows how many moles of a reactant are involved in the reaction. If there is no explicit coefficient, a value of 1 for the coefficient is assumed. The coefficient in front of the molecule tells its relative number of moles.
