1.

Fe +52 - Fe253

SYNTHESIS REACTION

A synthesis reaction occurs when two or more reactants combine to form a single product.

2.

Pb(NO3)2 + K2CrO 4 PbCrO 4 +KNO3

DOUBLE REPLACEMENT

A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.

3.

H2 + N2 + NH3

SYNTHESIS REACTION

A synthesis reaction occurs when two or more reactants combine to form a single product.

4.

Fe + CuCl2 - FeCl2 + Cu

SINGLE REPLACEMENT

A single-displacement reaction, is a chemical reaction in which one element replaces an/other element in a compound.

Note. An element can only replace an element that it is higher than in the electrochemical series or an element that is less reactive than itself.

5.

KCIO3 -KCI + O2

DECOMPOSITION REACTION

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.

Most times this type of reaction requires an in put of energy.

It is usually an endothermic reaction as heat is mostly absorbed.

6.

Mg + HCI-H2 + MgCl2

SINGLE REPLACEMENT

A single-displacement reaction, is a chemical reaction in which one element replaces an/other element in a compound.

Note. An element can only replace an element that it is higher than in the electrochemical series or an element that is less reactive than itself.

7.

C3Hg + O2 CO2 + H2O

COMBUSTION REACTION

Combustion reaction is a high-temperature exothermic redox chemical reaction between a fuel (example propane C3H8) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products.( mostly C02)

It can also be referred to as burning.

Combustion reaction is one of the chemical characteristics of hydrocarbons.

8.

Zn + HCI - ZnCl2 + H2

SINGLE REPLACEMENT

A single-displacement reaction, is a chemical reaction in which one element replaces an/other element in a compound.

Note. An element can only replace an element that it is higher than in the electrochemical series or an element that is less reactive than itself.
