Write the unbalanced equation to show the reactants and products. Write down how many atoms of each element there are on each side of the reaction arrow. 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.
How do you balance equations in chemistry?
- A chemical equation represents the changes that occur during a chemical reaction.
- Coefficients are used to balance chemical equations.
- To balance a chemical equation, place coefficients as needed in front of the symbols or formulas so the same number of each type of atom occurs in both reactants and products.
What are the 4 steps to balancing a 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 a chemical equation quickly?
How do you balance c2h6 o2 co2 h2o?
How do you balance ch4 o2 co2 h2o?
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.

Why do we balance chemical equations?
A chemical equation needs to be balanced so as to make the number of the atoms of the reactants equal to the number of the atoms of the products. Was this answer helpful?
What is the balanced equation for c2h4 o2 CO2 H2O?
What type of reaction is C2H6 o2 → CO2 H2O?

What type of reaction is CH4 O2 -> CO2 H2O?
The combustion of methane or octane is exothermic; it releases energy. CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants.
