Since there are more variables than equations, there are multiple solutions.See More….

• ### How do you balance a chemical equation with atoms?

• The next step for balancing the chemical equation is to determine how many atoms of each element are present on each side of the arrow: Fe + O 2 鈫?Fe 2 O 3 To do this, keep in mind a subscript indicates the number of atoms. For example, O 2 has 2 atoms of oxygen.

• ### How do you balance the chemical equation Fe O2?

• The next step for balancing the chemical equation is to determine how many atoms of each element are present on each side of the arrow: Fe + O2 鈫?Fe2O3. To do this, keep in mind a subscript indicates the number of atoms. For example, O2 has 2 atoms of oxygen. There are 2 atoms of iron and 3 atoms of oxygen in Fe2O3.

• ### How do you balance a chemical equation with a subscript?

• The subsequent step for balancing the chemical equation is to decide what number of atoms of every detail are a gift on every facet of the arrow: Fe + O2 鈫?Fe2Othree To do this, hold in thoughts a subscript shows the variety of atoms. For example, O2 has 2 atoms of oxygen.

• ### What is the last step in balancing chemical equations?

• When balancing chemical equations, the last step is to add coefficients to oxygen and hydrogen atoms. The reason is because they usually appear in multiple reactants and products, so if you tackle them first you’re usually making extra work for yourself.
