Reactants and Products

  • Reactants are the starting materials or ingredients.
  • Products are the result of the reaction or the final outcome.
  • In chemical equations, reactants are separated by a plus sign ($+$) to indicate they are reacting together.
  • The reactants are on the left side of the arrow, and the products are on the right side.
  • Arrow ($\rightarrow$) signifies the reaction, leading from reactants to products.

Measurements and Conservation of Mass

  • Measurements indicate the quantity of each reactant needed.
  • Conservation of mass: The amount of each element should be the same on both sides of the equation
