What is chemistry? Chemistry is a chemical subject. The chemistry is a part of science. Periodic table is designed to learn elements. The periodic mostly use in chemistry. Because the chemistry is chemical subject.
Father of chemistry Antoine Lavoisier is the father of chemistry. Born: 26 August , 1743 Age: 51 years Died: 8 May, 1794 Full name: Antoine-Laurent de Lavoisier
Nick name: father of modern chemistry.
What is the purpose of chemistry?
The purposes of chemistry is, to understand the universe and matter of the universe.
Chemicals
Now, it time to learn about chemicals.
The chemical contain a specific liquid with some elements.
Example: water, water contain some elements, they are.
Two atoms of hydrogen and oxygen
When the two atoms of hydrogen and oxygen mixture together, then the water will form.
H2o the chemical formula of water
H stand for hydrogen
2 stand for two atoms of hydrogen O stand for oxygen.
In Chemicals the elements will that place. Without elements the chemical will not form. Example: water.
Periodic table Now, it time to learn about periodic table. We can see all elements in the periodic table. They are 118 elements in periodic table.

Types of chemicals 5 Main Types of Chemical Reactions •
Synthesis reaction. Narrow definition. The other meaning of chemical synthesis is narrow and restricted to a specific kind of chemical reaction, a direct combination reaction, in which two or more reactants combine to form a single product. The general form of a direct combination reaction is: A + B → AB.
• Decomposition reaction. Chemical decomposition, analysis or breakdown is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds. Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis.
• Single displacement reaction. A single-displacement reaction, also known as a single-replacement reaction, is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound. This type of reaction is typically pictured like this: Here, A replaces B in the compound BC
• Double displacement reaction. • • • Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions. For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed. These reactions are ionic in nature
• Combustion reaction. Burning wood in a fire is an example of a combustion reaction. In the combustion reaction, the carbohydrates in wood combine with oxygen to form water and carbon dioxide. This reaction is very energetic, and it generates heat and light as it releases that energy. • Combination. 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.
• Redox Redox is a chemical reaction in which the oxidation states of atoms are changed. Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.
