Reactants
- Vinegar is acetic acid (C2H4O2) and water. Acetic acid is made of 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms.
- Baking soda is sodium bicarbonate (NaHCO3). Sodium bicarbonate is made of 1 sodium ion, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.

Products
- One of the products of the vinegar and baking soda reaction is sodium acetate (NaC2H3O2).
- Sodium acetate is made of 1 sodium ion, 2 carbon atoms, 3 hydrogen atoms, and 2 oxygen atoms.
- The other products are water (H2O) and carbon dioxide (CO2).

Mass is Conserved
- All of the atoms in the reactants are in the products.
- The mass of the reactants and products is the same.

Controlling Amount of Products Formed
- Adding more of one reactant will make more products as long as there is still enough of the other reactant to react.
- If you add more and more of one reactant the other will eventually run out and no more products will be formed.
