Question

Write the balanced chemical equation for the following reactions:
1.Aqueous solution of sulphuric acid and aqueous solution of sodium hydroxide react to form aqueous sodium sulphate solution and water.
2. Phosphorus burns in chlorine gas to form Phosphorus pentachloride.
(class 10 CBSE SAMPLE PAPER 2017-18 SCIENCE)

Answer 1

SOLUTION:

1.Aqueous solution of sulphuric acid and aqueous solution of sodium hydroxide react to form aqueous sodium sulphate solution and water.

CHEMICAL EQUATION:
H2SO4 (aq) +2NaOH(aq) -------> Na2SO4(aq) +2H2O(l)


2. Phosphorus burns in chlorine gas to form Phosphorus pentachloride.

CHEMICAL EQUATION:
P4 (s) + 10Cl2(g) --------> 4PCl5(s)

Answer 2

Hello friend! !

The balanced chemical equations for the above are given below :-

1.H2SO4 (aq) +2NaOH (aq)=Na2SO4 (aq)+2H2O (l)

2. P4 (s)+ 10Cl2 (g)=4PCl5 (s)

Hope that helps you! !
