A. Directions: Study the given reactants in Column A. Write the product of the chemical reactions in Column B disregarding whether it is balanced or not. Copy this in a separate sheet of paper. Remember: Gases like hydrogen, oxygen, nitrogen, chlorine, fluorine exists as diatomic under normal conditions. Bromine (liquid) and iodine (solid) also exist as diatomic under normal conditions. Therefore, they are written as H2, O2, N2₂. Cl2, F2, Br2 and 1₂. COLUMN A 1. C+ O2-> 2. KC103-> 3. PbCO3- 4. Cl₂ + NdaBr- 5. Al2(SO4)3 + CaCl₂- COLUMN B​
