Answer 1

Answer:

For balancing the equations , we have to see that if the number of atoms on both sides of a chemical equation are equal.

☘So by solving for this, the answers are :

$(a) FeS + O_2 \longrightarrow FeO + SO_2$

• $\sf{2FeS + 3O_2 \longrightarrow 2FeO + 2SO_2}$

____________________________________

$(b) Cu_2O + Cu_2S \longrightarrow Cu + SO_2$

• $\sf{2Cu_2O + Cu_2S \longrightarrow 6Cu + SO_2}$

____________________________________

$(c)Cu + HNO_3 (conc) \longrightarrow Cu(NO_3)_2 + NO_2 + H_2O$

• $\sf{Cu + 4HNO_3 (conc) \longrightarrow Cu(NO_3)_2 + 2NO_2 + 2H_2O}$

____________________________________

$(d)KMnO_4 + H_2SO_4 + H_2 S \longrightarrow K_2SO_4 + MnSO_4 + H_2O +S$

• $\sf{2KMnO_4 + 3H_2SO_4 + 5H_2S \longrightarrow K_2SO_4 + 2MnSO_4 + 8H_2O + 5S}$

$(e)CuO + CO \longrightarrow Cu +CO_2$

• $\sf{CuO + CO \longrightarrow Cu + CO_2}$
