How do you balance equations in chemistry?

  1. A chemical equation represents the changes that occur during a chemical reaction.
  2. Coefficients are used to balance chemical equations.
  3. 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.

Do you practice balancing chemical equations?

  • CO2 + H2O → C6H12O6 + O2
  • SiCl4 + H2O → H4SiO4 + HCl.
  • Al + HCl → AlCl3 + H2
  • Na2CO3 + HCl → NaCl + H2O + CO2
  • C7H6O2 + O2 → CO2 + H2O.
  • Fe2(SO4)3 + KOH → K2SO4 + Fe(OH)3
  • Ca3(PO4)2 + SiO2 → P4O10 + CaSiO3
  • KClO3 → KClO4 + KCl.

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.
