Why do we balance a chemical equation?

A chemical equation should always be balanced because the law of conservation of mass states that matter can neither be created nor destroyed so in a chemical equation the total mass of reactants must be equal to the mass of products formed i.e. the total number of atoms of each element should be equal on both the …

What is a unbalanced equation?

If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation.

What is a balanced equation in math?

A balanced equation is an equation where both sides are equal to the same amount. The answer to the expression on the left side of the equals sign (=) should be equal to the value on the right side of the equals sign. Or the right hand side of the equation has a greater value than the left side, like the example below.

How do you write a chemical equation?

Writing Chemical Equations

1. In a chemical equation, the reactants are written on the left, and the products are written on the right.
2. The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.

Is chemical an equation?

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side with a plus sign between the entities in both the reactants and the products and an arrow that …

What are the 5 chemical equation?

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories.

What is an example of chemical equation?

Reactants are converted to products, and the process is symbolized by a chemical equation. For example, iron (Fe) and sulfur (S) combine to form iron sulfide (FeS). Fe(s) + S(s) → FeS(s) The plus sign indicates that iron reacts with sulfur.

What happens if a chemical equation is not balanced?

If a chemical equation is not balanced it implies that either mass has been created or destroyed which is a contradiction to law of conversation of mass which states that matter can niether be created nor destroyed .
