What Are The 4 Steps To Balancing A Chemical Equation. Steps in balancing a chemical equation. Count the number of atoms of each element in the reactants and the products.
The unbalanced chemical equation must be obtained by writing the chemical formulae of the reactants and the products. For example your equation should look something like h2 o2 h2o count the number of atoms in each element on each side of the equation and list them under that side. Extending this symbolism to represent both the identities and the relative quantities of substances undergoing a chemical or physical change involves writing and balancing a chemical equation.
Add coefficients the numbers in front of the formulas so the number of atoms of each element is the same on both sides of the equation.
First write the unbalanced chemical equation. In this example the reactants are glucose c 6 h 12 o 6 and oxygen o 2 and the products are carbon dioxide co 2 and water h 2 o the unbalanced chemical equation is c 6 h 12 o 6 o 2 co 2 h 2 o. For example your equation should look something like h2 o2 h2o count the number of atoms in each element on each side of the equation and list them under that side. To balance a chemical equation first write out your given formula with the reactants on the left of the arrow and the products on the right.
