For eg.-
Zn+HCl- Zncl+H2

Answer 2

1.all metals react with oxygen to form metal oxides.
2. Metals react with water to produce metal oxide or (metal hydroxides) and hydrogen gas.
3. Metals react with dilute acid to form metal salt and hydrogen gas.
4. All metals react with chlorine to form ionic metal chloride.
