Answers
Explanation:
WORKED EXAMPLE 1: BALANCING CHEMICAL EQUATIONS 1
Balance the following equation:
Mg+HCl→MgCl2+H2
Identify the reactants and products
This has been done in the question.
Write the equation for the reaction
This has been done in the question.
Count the number of atoms of each element in the reactants and products
Reactants: Mg=1 atom, H=1 atom, Cl=1 atom
Products: Mg=1 atom, H=2 atoms, Cl=2 atoms
Balance the equation
The equation is not balanced since there are two chlorine atoms in the product and only one in the reactants. If we add a coefficient of two to the HCl to increase the number of H and Cl atoms in the reactants, the equation will look like this:
Mg+2HCl→MgCl2+H2
Check that the atoms are balanced
If we count the atoms on each side of the equation, we find the following:
Reactants: Mg=1 atom, H=2 atoms, Cl=2 atoms
Products: Mg=1 atom, H=2 atoms, Cl=2 atoms
The equation is balanced. The final equation is:
Mg+2HCl→MgCl2+H2
