Answer 1

Answer:

1) sodium + water = sodium hydroxide + hydrogen gas.

➡ Na + H2O = NaOH + H2

2) calcium + water = calcium hydroxide + hydrogen gas.

➡ Ca + H2O = Ca(OH)2 + H2

3) Magnesium + Water = Magnesium oxide + hydrogen gas.

➡ Mg + H2O = MgO + H2

4) Iron + water = iron oxide + hydrogen gas

➡ 4 Fe + 6 H2O = 2Fe2O3 + 6 H2

5) Carbon + water = carbon usually does not react with water.

6) Silicon + water = silicon dioxide+ hydrogen

➡ Si + 2H2O = SiO2 + 2H. 2
