  1. 3. Type of reaction where a single reactant breaks down into two or more simpler products.
  2. 8. A symbolic representation of a chemical reaction using formulas and symbols.
  3. 9. Type of reaction where one element replaces another in a compound.
  4. 10. A small number written below an element symbol indicating the number of atoms in a molecule (e.g., the "₂" in H₂O).
  5. 11. A number placed in front of a chemical formula to balance the equation.
  6. 12. A chemical equation that shows the formulas of reactants and products but is not balanced.
  7. 13. Type of reaction where two or more reactants combine to form a single product.

  1. 1. The starting substances in a chemical reaction, found on the left side of the equation.
  2. 2. Type of reaction where two compounds exchange elements to form two new compounds.
  3. 4. The substances formed in a chemical reaction, found on the right side of the equation.
  4. 5. A chemical equation where the number of atoms of each element is the same on both sides, ensuring the law of conservation of mass is followed.
  5. 6. Type of reaction where a substance (usually a hydrocarbon) reacts with oxygen to produce carbon dioxide and water.
  6. 7. A representation of a substance using chemical symbols and numbers (e.g., H₂O, CO₂).
  7. 8. The one or two-letter abbreviation for an element (e.g., H for hydrogen, O for oxygen).
