What to Focus On

  • Physical change usually changes state or form, not composition.
  • Chemical change changes the composition of matter.
  • Reactants are starting substances.
  • Reactants are written on the left side.
  • Products are written on the right side.
  • The arrow shows the direction of reaction.
  • Heating limestone gives calcium oxide and carbon dioxide.
  • Copper with concentrated nitric acid gives NO2.
  • Copper with dilute nitric acid gives NO.

Common Mistakes to Avoid

Balancing a chemical equation means changing the formulas of compounds until the atom count matches.

A chemical equation is balanced only when the number of molecules is the same on both sides.

The upward arrow and downward arrow are just decoration and can be ignored.
