Question

b) Complete the given below reactions
Zn + Hcl -
Na + Hcl -
Zn + NaOH -
What you conclude from the given above reactions
​

Answer 1

Explanation:

zn+hcl======>zncl2+h2

Na+HCl=====>Nacl+h2

Zn+NaOH====>Na2ZnO2+h2

when metals react with acids or bases they liberate hydrogen gas

Answer 2

first of all balance the reaction

Explanation:

1..Zn+2HCl _______ZnCl2+H2

2..2Na +2HCl,________2NaCl+H2

3..Zn+2NaOH_________Na2ZnO2+H2
