WRITING CHEMICAL EQUATIONS

 A chemical equation must be balanced
 Make sure there always be the same number of atoms of each element on both side of the equation


REACTANTS → PRODUCTS


Example
1. Magnesium reacts with dilute hydrochloric acid to produce magnesium chloride and hydrogen gas. Write an equation to represent the reaction.

Step 1 : Write the correct chemical formula for each reactant and product

Mg + HCl → MgCl2 + H2

Step 2 : Balance the equation. Adjust the coefficients in front of the chemical formulae and not the subscripts in the formulae.

Mg + 2HCl → MgCl2 + H2
