Question

give one example each of displacement decomposition and combination reaction with explanation

Answer 1

a more reactive metal can displace a less reactive metal from its salt solution. The reaction is termed as displacement reaction . for example
Fe+Cuso4—>FeSO 4 + CU

decomposition reaction is a type of reaction and which a reactant breaks into two for example
2 H2O 2—> 2 H2O + O2


a combination reaction is a type of reaction in which two or more reactants combine to form a single compound for example
N a + Cl —>NaCl

Answer 2

hey mate ✋✋

✔✔here's your answer ✔✔

$\underline \bold{Displacement \: reaction:}$

The reaction where a more reactive element displaces another element from its compound is called displacement reaction.

$\underline \bold {example = } \: Fe + CuSO_{4} - - - - > FeSO_{4} + Cu$

$\underline \bold{Decomposition \: reaction:}$
The reaction where a single reactant decomposes to form two or more products.

$\underline \bold {example = } \: CaCO_{3} - - - - >CaO + CO_{2}$

$\underline \bold{Combination \: reaction:}$

The reaction where two or more reactants combines to form a single product is called combination reaction.

$\underline \bold {example = } \: C + O_{2} - - - - > CO_{2}$

hope it helps u ✌✌
