Answer: Option (b) is the correct answer.
Explanation:
It is given that mass of Mg is 97.22 g and it is known that molar mass of Mg is 24.305 g/mol.
So, calculate the number of moles as follows.
No. of moles = 
= 
= 4 mol
Also, it is known that 1 mole has 
atoms/mol. Therefore, calculate the number of atoms in 4 mol as follows.
= 
atoms
or, = 
atoms
Thus, we can conclude that there are atoms in 97.22 grams of Mg.
Explanation:
The cleansing action of soaps is predicated on the nature of soaps as we have it.
- A soap has the ability to remove dirt from materials.
- The cleansing action of a soap is related to the structure of its molecule.
- A molecule of soap has dual structure with polar head that is water loving and a long hydrocarbon tail which is hydrophobic.
- The structure enables soap molecules to emulsify an organic dirt present on a fabric in water.
- The soap causes the suspension of tiny oil droplets in the aqueous medium.
Answer:Argon is an element on the periodic table. It is a member of the noble gasses, meaning that it is a monoatomic pure gas. In other words, argon gas particles are simply pure single atoms of argon. ... Finally, water is a polyatomic molecule H2O composed of two atoms of hydrogen and one atom of oxygen.
Explanation:
In my point of view,
if two different forces act on two different directions the net force acting is the difference between them
So,4n-4n=0n
