Answer:
Sure, here are some examples of each type of reaction:
Combination reaction:
1. 2H2 + O2 -> 2H2O (formation of water)
2. CaO + H2O -> Ca(OH)2 (formation of calcium hydroxide)
3. N2 + 3H2 -> 2NH3 (formation of ammonia)
Decomposition reaction:
1. 2HgO -> 2Hg + O2 (decomposition of mercury oxide)
2. CaCO3 -> CaO + CO2 (decomposition of calcium carbonate)
3. 2KClO3 -> 2KCl + 3O2 (decomposition of potassium chlorate)
Displacement reaction:
1. Fe + CuSO4 -> FeSO4 + Cu (iron displaces copper from copper sulfate)
2. Mg + 2HCl -> MgCl2 + H2 (magnesium displaces hydrogen from hydrochloric acid)
3. Zn + 2HCl -> ZnCl2 + H2 (zinc displaces hydrogen from hydrochloric acid)
Combination reaction : The one in which two or more reactants combine to give a single product.
These are some xamples :
[tex]\rm C + O_2 \longrightarrow CO_2[/tex]
[tex]\rm H_2 + O_2 \longrightarrow H_2O[/tex]
[tex]\rm CaO + H_2O \longrightarrow Ca(OH)_2[/tex]
You can have many more
Displacement reaction : The one in which a higher reactive element displaces a lesser reactive element from its salt solution
Examples: (See reactivity series to infer)
[tex]\rm CuSO_4 + Fe \longrightarrow FeSO_4 + Cu [/tex]
[tex]\rm Zn + CuCl_2 \longrightarrow ZnCl_2 + Cu[/tex]
You can make many more examples based on reactivity series
Decomposition reaction : The reaction in which one reactant decomposes to give 2 or more products.
Examples:
[tex]\rm HgO \longrightarrow Hg + O_2 [/tex]
[tex]\rm CaCO_3 \longrightarrow CaO + CO_2[/tex]
Tip ; Balance all reactions and list their states (solid, liquid, gas, aqua) to have a elegant reaction.
I have given my answer based on my class 10th knowledge left today (its been 4 years).
i hope it will help you, you may also refer NCERT as it has mentioned all reactions
