Did you know facts about chemical reaction?
Most of the chemical reactions cause changes which are non-reversible. A few of them can be reversed. Chemical reactions or changes produce new materials. Some chemical reactions produce energy while rest of them absorb energy.
Who invented chemistry?
Lavoisier has been considered by many scholars to be the “father of chemistry”. Chemists continued to discover new compounds in the 1800s. The science also began to develop a more theoretical foundation. John Dalton (1766-1844) put forth his atomic theory in 1807.

What is the basic knowledge of chemistry?
Chemistry is the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.
What is chemistry in daily life?
Ans: Some examples of chemistry in everyday life include respiration, digestion, photosynthesis, cooking food, burning of fuel like coal and petroleum, cleaning clothes and utensils, and many more. All these activities are performed by us in our daily life, and they undergo some chemical reactions.
What are the basic things to know in chemistry?

How chemistry affects our life?
Answer: Everything in our environment is formed of matter. Chemistry is significant in our civilization because it affects our basic needs for food, clothing, shelter, health, energy, and clean air, water, and soil, among other things.
Why is chemistry useful?
Chemistry is essential for meeting our basic needs of food, clothing, shelter, health, energy, and clean air, water, and soil. Chemical technologies enrich our quality of life in numerous ways by providing new solutions to problems in health, materials, and energy usage.
Why is chemistry so hard?
The primary reason chemistry is so hard is because of the topic progression. You really have to fully understand several topics before you can fully understand other topics. It’s important to keep in mind, memorization isn’t the key here. There’s a certain element of memorization.
What are 4 important facts about atoms?

- Atoms are the smallest particles that make up elements.
- Atoms are mostly empty space.
- There are over 100 different kinds of atoms.
- The components of an atom are held together by three forces.
What are 3 facts of physical changes?
In a physical change, the material involved in the change is structurally the same before and after the change. Types of some physical changes are texture, shape, temperature, and a change in the state of matter. A change in the texture of a substance is a change in the way it feels.
What are two facts about chemical energy?
Interesting Chemical Energy Facts: Chemical energy is stored inside a substance or object until it is involved in a chemical reaction. Our bodies use chemical energy to perform daily functions. During an exothermic chemical reaction, chemical energy in the form of heat is released.
What is the old name of chemistry?
The word chemistry derives from the word alchemy, which is found in various forms in European languages. Alchemy derives from the Arabic word kimiya (كيمياء) or al-kīmiyāʾ (الكيمياء).
What are the 5 types of chemistry?
In a more formal sense, chemistry is traditionally divided into five major subdisciplines: organic chemistry, biochemistry, inorganic chemistry, analytical chemistry, and physical chemistry.
Who is called Father of chemistry?
1. Who is the real father of chemistry? The real father of chemistry is Antoine Lavoisier.
