Answer:

Step-by-step explanation:

Displacement reaction :

A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one

(or more) element(s) replaces an/other element(s) in a compound. It can be represented generally as:

A+B−C→A−C+B

All simple metal with acid reactions are single displacement reactions. For example, the reaction

between magnesium, Mg, and hydrochloric acid, HCl, forms magnesium chloride, MgCl

2

, and hydrogen,

H

2

.

Mg(s)+2HCl(aq)→MgCl

2

(aq)+H

(g)

Decomposition reaction :

A decomposition reaction is a type of chemical reaction where one reactant yields two or more

products.

The general form for a decomposition reaction is

AB→A+B

Water can be separated by electrolysis into hydrogen gas and oxygen gas through the decomposition

reaction: 2H

O→2H

+O

Another example is the spontaneous decomposition of hydrogen peroxide into water and oxygen: 2

H

O

→2H

O+O

The decomposition of potassium chlorate into potassium chloride and oxygen is yet another example:

2KClO

3

→2KCl+3O

Combination reaction :

A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements

or compounds (reactants) combine to form a single compound (product). Such reactions may be

represented by equations of the following form : X+Y→XY.

Formation of calcium oxide by the combination elements calcium and oxygen.

2Ca+O

2

→2CaO

Formation of ammonia by the combination of elements nitrogen and hydrogen.

+3H

→2NH

The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.

Decomposition. ... In this equation, the water is “decomposed” into hydrogen and oxygen, both of which are neutral. Similar to the previous example, H2O has a total oxidation state of 0, with each H taking on a +1 state and the O a -2; thus, decomposition oxidizes oxygen from -2 to 0 and reduces hydrogen from +1 to 0.
