What is a balanced formula equation?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. Also Known As: Balancing the equation, balancing the reaction, conservation of charge and mass.

What is balanced chemical equation example?

A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. In this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to produce ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.

What are the steps to balancing equations?

Change the coefficients (the numbers in front of the compound or molecule) so that the number of atoms of the element is the same on each side of the equation. Remember, to balance an equation, you change the coefficients, not the subscripts in the formulas.

Why do we balance equations?

An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.

How do you write a balanced chemical equation?

Identify the reactants and the products in the reaction and write their chemical formulae. Write the equation by putting the reactants on the left of the arrow and the products on the right. Count the number of atoms of each element in the reactants and the number of atoms of each element in the products.

What is a balanced and unbalanced equation?

IMPORTANT DEFINITION: A balanced equation has equal numbers of each type of atom on each side of the equation. It is an unbalanced equation (sometimes also called a skeleton equation). This means that there are UNEQUAL numbers at least one atom on each side of the arrow.

How do you balance an equation algebraically?

The strategy for balancing chemical equations algebraically is as follows:Write a different letter coefficient in front of each compound in the equation.Write algebraic expressions or rules for each element that equate its atoms on the LHS and RHS.

What is the balanced equation for Na cl2 nacl?

1 Answer. The balanced equation is 2Na(s)+Cl2(g) → 2NaCl(s) .
