Question

Hey...A challenge to all chemistry lover...can u solve the following​

Answer 1

Hey mate!!

1) When Iodine crystals are heated, the boond between the molecules break and turn to gaseous state. They form a purple coloured dense vapor.

2)coppersulphate change its color from blue to light green. This shows Iron is more reactive than Copper, it can replace Copper from CuSO4. CuSO4 is in blue Color and FeSO4 is in light green color.

3)lead nitrate is heated strongly a it turns yellow due to formation of lead oxide and a reddish brown gas is evolved which is nitrogen dioxide

4)ferric chloride absorbs moisture from the air and changes its state.

5)The blue coloured copper sulphate crystals turns white due to the loss of water molecules.

Hope this helps you

Mark as brainliest.

Answer 2

1) they form purple color dense flame.

2) the colour of cuso4 solution is changed green from blue.(displacement reaction)

3) it decompose into lead oxide, nitrogen dioxide an o2

4) it absorbs moisture and gets converted into solution

5)it loses it colour and turns white due to loss of water molecules
