Question

it
it is necessary to know the chemical reaction occurring around us number should visit the nearby and collect the following and do the following activities iron nail c s o4 Sodium and magnesium and reason for resource for recipe

Answer 1

Observations by performing the experiments :
1) Iron nail + CuSO4 solution:
When iron nail is dipped in copper sulphate solution, the copper gets coated on iron because a chemical displacement reaction occurs where iron being more reactive displaces Copper from copper sulphate solution.The blue colour of copper sulphate will change to green colour because of formation of ferrous sulphate.
Fe+CuSO4---> FeSO4 +Cu

II) When iron nail reacts with hot water :
 iron reacts with steam and forms iron (iii)oxide and hydrogen gas
3Fe +4H2O ---> Fe3O4 + 4H2 

Iron reats with cold water to form Iron oxide
4Fe +6H20 ----> 2Fe2O3 +3H2

iii)Sodium reacts with cold water vigorously forming NaOH and Hydrogen gas
2Na + 2H2O-----> 2NaOH +H2

Iv)Magnesium metal is not as reactive as Sodium . so it reacts only with steam or Hot water to form magnesium hydroxide and Hydrogen gas.

V)Fe<Mg<Na  is the increasing order of reactivity

VI)Among the given options :
Metals are : Sodium, Magnesium and iron
Non metals are : Sulphur and phosphorous.
