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
