Question

1. Identify the type of reaction in the following examples: (i.) Na2 So4(aq)+ Bacl2(aq)→BaSo4(s)+ Nacl(aq) (ii.) Fe(s)+ CuSo4(aq)→ FeSo4(s)+Cu(s) (iii.) 2H2(g)+ O2(g)→2H2O(l)

Answer 1

1st one is souble displacement reavtion
2nd one os simple displacement reaction
3rd ome is combination reaction

Answer 2

Answer:

i. $Na_2SO_4(aq)+ BaCl_2(aq)\rightarrow BaSO_4(s)+NaCl(aq)$ : double displacement

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

ii. $Fe(s)+CuSO4(aq)\rightarrow FeSO4(s)+Cu(s)$ : Single replacement

Single replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

iii. $2H_2(g)+O_2(g)\rightarrow 2H_2O(l)$: Synthesis reaction

Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.
