Answers:
Bohr's model agrees with Thompson's model as both hold the fact that there are three sub=atomic particles which makes up an atom and there are equal number of protons and electron in a neutral atom
Explanation:
Bohr's model describes an atom as a planetary like shape in which the electrons revolve round the nucleus which is composed of protons and neutrons.
Thompson's model states an atom as a sphere which is composed of electrons surrounded by positively charged ions.

Answer:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
How are physical and chemical changes similar and different? (compare and contrast) (Physical and chemical changes are similar because matter experiences a change in state, Physical changes are different because matter remains the same substance, just in a different state, whereas chemical changes change the matter
Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical changes can be undone, if energy is input. The only way to reverse a chemical change is via another chemical changes.
Explanation:
Answer: There are 6 mole of oxygen present in 1 mole of .
Explanation:
The given formula of compound is . In this compound, there are 1 mole of magnesium, 2 mole of chlorine and mole of oxygen atom.
Therefore, we can conclude that the total number of moles of oxygen atoms present in 1 mole of is 6 mole.
In every day life work is a job while in scientific terms the work is a change in energy due to applied force and displacement.
Work(Job) -
In every day life, work means an specific job that is assigned to people.
For example: I work as account assistant in the company.
Work:
In scientific terms the work is a product of applied force and displacement. It is measured in Joule.
For example- the engine did the 10 J of work.
Therefore, in every day life work is a job while in scientific terms the work is a change in energy due to applied force and displacement.
