Chemistry, asked by arnavashree2410, 1 year ago

Translate the following statements into chemical equations and then balance the equations:
1) Phosphorus burns in oxygen to give Phosphorus pent oxide.
2) Carbon disulphide burns in air to give carbon dioxide and Sulphur dioxide.
3) When a nail of iron is added to a solution of copper sulphate, iron (II) Sulphate and Copper metal are formed.
4) Zinc reacts with dilute hydrochloric acid to form zinc chloride and hydrogen gas is obtained.

Answer:

Explanation:

1)   phosphorous burns in oxygen to give phosphorous pentoxide.

4P(s) + 5O2 (g)------>  2P2O5(s)

2) Carbon di sulphide burns in air to give carbon dioxide and Sulphur dioxide:

CS2 (s) +  3O2(g) -------> 2SO2 (g)+ CO2(g)

3) (at last)

4) when zinc reacts with dil.hydrochloric acid:

Zn + HCl = H2 + ZnCl2

It is a single displacement reaction where -

Zinc is oxidised (it becomes positive) and water is neutralized. It is a reduction-oxidation reaction where one of the reactants loses oxygen and the other one gains.

So, answering your question, we get hydrogen gas and a salt.

Hydrogen gas, is identified by exposing it to a burning flame. It explodes (a bit,) with a pop sound. This is because Hydrogen is highly explosive.

3)when iron nail and copper metal are formed:

Iron nails(Fe),CuSO4 will react:

Fe+CuSO4 → FeSO4 + Cu

This is a displacement reaction where Iron replaces the Copper in Copper sulfate to form Iron sulfate. This is because iron is more reactive than copper.
