Combination reaction
Decomposition reaction
Displacement reaction
Neutralisation reaction

Answer 1

Answer:

Hi mate

Explanation:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.

4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g) is an example of displacement as well as redox reaction. Oxygen displaces hydrogen of ammonia. Hence, this ...

Answer 2

Chemical reaction is the process by which new substance with new properties are formed

eg Mg+O2 gives MgO

Combination reaction is a reaction in which two substances react to form a single substance.

Eg Mg+O2 gives MgO

Decomposition reaction is a reaction in which one compound is split into two or more elements.

Eg respiration C6H12O6 + 6O2 gives 6CO2 + 6H2O

+ heat

Displacement reaction is a reaction in which the more reactive element displaces the less reactive element.

eg potassium iodide + lead nitrate gives lead iodide+ potassium nitrate.

i don't know Neutralization reaction I am sorry

but I hope this helps!
