The correct formulas of the reactants are always written on the left side of the equation. The correct formulas of the products are always written on the right side of the equation. The reactants and products are separated by an arrow pointing toward the products.
What are the 4 steps to writing a balanced chemical equation?
- Step 1: Make a Table. In a chemical equation there are subscripts and coefficients.
- Step 2: Determining and Balancing the First Element. Pick an element that appears in one molecule on the left side and in one molecule on the left.
- Step 3: Balancing Hydrogen.
- Step 4: Balancing Oxygen.
How do you balance chemical equations step by step?
What are the 3 rules for balancing equations?
- Check that all the formulae in the equation are correct.
- Deal with only one element at a time.
- Balancing is adding BIG numbers. You cannot change any of the small numbers in a chemical formula.
- Check each element again and repeat step 3 again if needed.
