Question
- Write word and balanced chemical equations for the reactions between:a sodium and waterb magnesium and steamc calcium and oxygend bromine and potassium iodide solutione zinc and copper sulfate solution.
Solution
a) Sodium and Water: Word Equation: Sodium + Water -> Sodium Hydroxide + Hydrogen Balanced Chemical Equation: 2Na(s) + 2H2O(l) -> 2NaOH(aq) + H2(g)
b) Magnesium and Steam: Word Equation: Magnesium + Steam -> Magnesium Oxide + Hydrogen Balanced Chemical Equation: Mg(s) + H2O(g) -> MgO(s) + H2(g)
c) Calcium and Oxygen: Word Equation: Calcium + Oxygen -> Calcium Oxide Balanced Chemical Equation: 2Ca(s) + O2(g) -> 2CaO(s)
d) Bromine and Potassium Iodide Solution: Word Equation: Bromine + Potassium Iodide -> Potassium Bromide + Iodine Balanced Chemical Equation: Br2(aq) + 2KI(aq) -> 2KBr(aq) + I2(s)
e) Zinc and Copper Sulfate Solution: Word Equation: Zinc + Copper Sulfate -> Zinc Sulfate + Copper Balanced Chemical Equation: Zn(s) + CuSO4(aq) -> ZnSO4(aq) + Cu(s)
