What is combination reaction?

what is combination reaction

the combination reaction is a one type of reaction in which two or more compound or reactants it is combined together to form a single compound or single product.

these type of reaction is represent by following equation,

For example: –

Combination reaction

A + B – AB Or

X + Y – XY

the combination of two Or more reactants to form a single reactants Or single compound is called combination reaction.

Example of combination reaction

First example;

Magnesium carbonate MgCO3

Combination reaction of magnesium carbonate;

Example of combination reaction is repersent by following equation such as,

A + B – AB

these are the write example of combination reaction because,

in this reaction, two or more reactants combined and to form a single compound. this reaction is more sutable example of combination reaction.

For example;

Formation of magnesium carbonate by the combination elements mgo and co2.

(a) X + Y – XY

MgO + CO2 – MgCO3

Where,

Mgo – X first reactants and,

CO2 – Y second reactants

Both are combined together to form a single compound. and the single compound is magnesium carbonate (MgCO3).

Structure of magnesium carbonate

Structure of magnesium carbonate

Properties of magnesium carbonate

1. Formula – MgCO3

2. Density – 2.96 g/cm3

3. Boiling point – 333.6°C

4. Melting point – 990°C

Uses of magnesium carbonate

  1. It is mostly used in manufacturing of cosmetics products.
  2. It is windly used in prepared printing ink.
  3. It is also used in medical department.

similarly,

Second example;

Calcium hydroxide – ca(OH)2

What is calcium hydroxide?

what is combination reaction

Calcium hydroxide is an inorganic compound with the chemical formula ca(OH)2. it is colorless white powder. it is also called lime water.

Combination reaction of calcium hydroxide

Formation of calcium hydroxide Ca(OH)2 by combination elements calcium oxide and water.

this reaction is more sutable for the example of combination reaction.

in this case, one Or two reactant combined together and make a single compound or product

it is represent by following equation such as,

(b) X + Y – XY

CaO + H20 – Ca(OH)2

where,

X – one reactant

(One or two reactant)

Y – two reactant,

when calcium oxide combined with water then it is given calcium hydroxide as a single compound or single product.

Properties of calcium hydroxide

1. Chemical formula – Ca(OH)2

2. Density – 2.211 g/cm3

3. Molar mass – 74.093 g/mol

4. Solubility in water – 1.89 g/l (0°C)

5. Melting point – 580°C (853k)

6. Colour – white (white powder)

Uses of calcium hydroxide

1. It is mainly used as reagent in plastic industry.

2. it is also used in leather industry.

3. It is used in preparation of chemicals and pH modifier.

Freqently Asked Question

the product of a combination reaction is ba(oh)2, if one of the reactants is h2o

the product of a combination reaction is ba(oh)2 if one of the reactants is h2o what is the other reactant?

Ans:- we know that, the combination reaction of ba(oh) 2 is, the combination in between two reactants, such as,

first, reactants is – H2O

Second, reactants is – Bao

these both reactants combined together then it is given ba(oh)2 as a product.

For example;

X + Y – XY

h2o + bao – ba(oh) 2

these are called combination reaction.

So, Write Answer is – the product of a combination reaction is ba(oh)2 if one of the reactants is h2o, and other reactants is Bao.

how does a combination reaction differ from a decomposition reaction?

Yes, it is true both are different reaction.

Combination reaction – the combination reaction is a one type of reaction in which two or more compound or reactant, it is combined together to form a single compound or single product.

Or,

the combination of two Or more reactants to form a single reactants Or single compound is called combination reaction.

For example;

A + B = AB

X + Y = XY

you can understand properly with the following reaction;

Cao + H2O = Ca(OH)2

Reactant Product

similarly;

Decomposition reaction – decomposition reaction is one type of reaction in which a compound breck down into two or more simpler substance.

For example;

AB = A + B

XY = X + Y

You can understand properly with the following reaction,

NaCl = Na + Cl

Reactant Product

Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide?

there are 4 major types of combination reaction, such as,

Types of chemical reaction;

1. Combination reaction

2. Decomposition reaction

3.displacement reaction

4. Double displacement reaction

these are the important 4 menor type of combination reaction.

Now, according to question, when calcium oxide react with water then it is given calcium hydroxide.

You can understand with the reaction,

CaO + H2O – Ca(OH)2

Reactant Product

if you see carefully, this reaction is same as combination reaction because the combination reaction is a one type of reaction in which two or more compound or reactant, it is combined together to form a single compound or single product

After reaction it release large amount of heat.

What is the product (s) in the combination reaction Mgo + CO2

Combination reaction:- it is a combination reaction in which two or more reactants combined together to form a single product Or a single compound.

The combination reaction will be:-

For example: –

A + B – AB

MgO + CO2 – Mg CO3

this types of reaction is called combination reaction in which one reactants or element such as mgo and second reactants is CO2. both reactants combined together to form a MgCO3 as a product or as a compound.

Write answer is; – the product of combination reaction mgo + co2 is MgCO3.

How calcium oxide reacts with water in a combination reaction to produce calcium hydroxide?

here, we will explain with help of following reaction;

when calcium oxide reacts with water then it will convert to calcium hydroxide. this reaction is also called combination reaction.

For example;

A + B – AB

CaO + H2O – Ca(OH)2

reactant product

this is the one type of reaction in which two or more reactants combined together and it converted to a single compound.

It release large amount of heat after reaction
