Cell is surprising or interesting to learn about the very small organisms and objects in today’s lesson.
What is cell?Cell is defined as the basic unit of life or it has been structural or functional unit of life. Cell contain many cell organelles and all the cell organelles have various functions such as nucleus is the brain of the cell and it controls all the function of the cell.
Cell is of two types eukaryotic and prokaryotic cell and the cell which are advanced and developed is known as eukaryotic and the cell which are not much developed and does not contain cell organelles is known as prokaryotic cell. Cell contain many cell organelles and all the cell organelles have various functions such as nucleus is the brain of the cell and it controls all the function of the cell.
Multicellular organism is made up of eukaryotic cell and unicellular is made up of prokaryotic cell. Cell is always developed from pre existing cell and it has been the structural and functional unit of life. Cell is the building block of an individual.

There are four atoms of hydrogen (H) before the reaction. How many atoms of hydrogen are present after the reaction?
4
8
5
2
Answer:
2
Explanation:
The number of atoms of hydrogen that are present after the reaction is 4. The correct option is the first option - 4
Law of conservation of massFrom the question,
We are to determine the number of atoms of hydrogen present after the reaction.
From the law of conservation of mass which states that
"Matter can neither be created nor destroyed"
This means, the number of atoms are the same before and after the chemical reaction.
Since the number of hydrogen atoms before the reaction is four, then there would be four hydrogen atoms after the reaction.
Hence, the number of atoms of hydrogen that are present after the reaction is 4. The correct option is the first option - 4

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the correct option is option A.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Oxygen is the only thing for which humans depend on marine plants. Oxygen is very important for humans.
Therefore, the correct option is option A.

A.nucleus and its particles
B.negatively-charged particles
C.neutrally-charged particles
D.positively-charged particles
Answer: Valence electrons are involved in a chemical reaction.
Explanation:
A chemical reaction takes place when there is an involvement of valence electrons. Bond formation involves either sharing of valence electrons or transfer of valence electrons. Bond breaking involves the separation of valence electrons.
When valence electrons are shared between the atoms, it leads to the formation of covalent bond.
When transfer of electrons takes place from one atom to another atom, it leads to the formation of ionic bond.
Hence, valence electrons are involved in a chemical reaction.
I think is A
The part of an atom is involved in chemical reactions is the nucleus and its particles. Therefore, option A is correct.
What is chemical reaction ?In a chemical reaction, one or more substances—also known as reactants—are changed into one or more additional substances—also known as products.
Breaking chemical bonds between reactant molecules (particles) and creating new bonds between atoms in product particles are two aspects of chemical reactions (molecules). While there are the same number of atoms both before and after the chemical transition, there will be a change in the number of molecules.
The electron cloud is the area of the atom that participates in chemical reactions. The region of the atom that surrounds the nucleus is known as the electron cloud. The electron cloud contains electrons, which are the particle in charge of causing the reaction to take place.
Thus, option A is correct.
