Question

explain with equation what happens when:
1.hydrochloric acid is poured on Aluminium foils.
2.sodium is placed in water.
3.zinc granules are kept in copper sulphate solution. ​

Answer 1

Answer:

2.when sodium is placed in water sodium displace hudrogen from water.

Na+H2O----------->Na2O+H2

Answer 2

Hii buddy!

Answer:

All the questions are based on '' Displacement Reaction ''.

Explanation:

1. $2al \: + 6hcl \: = 2alcl3 \: + 3h2$
2. $na \: + 2h2o \: = na(oh)2 \: + h2$
3. $zn \: + cuso4 = znso4 \: + cu$

1. In reaction 1 Aluminum displaces h2 from its salt solution.
2. In reaction 2 Na gets converted into its hydroxide.. This reaction is highly exothermic.
3. In reaction 3 Zinc displaces Copper from its salt solution.
