739 is the number of atoms of O in 92.3 moles of Cr3(PO4)2.
Explanation:
Molecular formula given is = Cr3(PO4)2
number of moles of the compound is 92.3 moles
number of 0 atoms in 92.3 moles =?
From the chemical formula 1 mole of the compound has 8 atoms of oxygen
So, it can be written as
1 mole Cr3(PO4)2 has 8 atoms of oxygen
92.3 moles of Cr3(PO4)2 has x atoms of oxygen
=
x = 8 x 92.3
x = 738.4 atoms
There will be 739 oxygen atoms in the 92.3 moles of Cr3(PO4)2.

Explanation:
The reaction that we are considering here is quite a knotty reaction. It is difficult to decide if the mechanism is actually E1 or E2 since both are equally probable based on the mass of scientific evidence regarding this reaction. However, we can easily assume that the methylenecyclohexane was formed by an E1 mechanism.
Looking at the products, one could convincingly assert that the reaction leading to the formation of the two main products proceeds via an E1 mechanism with the formation of a carbocation intermediate as has been shown in mechanism attached to this answer. Possible rearrangement of the carbocation yields the 3-methylcyclohexene product.

Answer:
"3. Energy can either be destroyed or created. Its goes from one form to another."
Explanation:
The third answer choice, "3. Energy can either be destroyed or created. Its goes from one form to another. " is related to the Law of Conservation of Energy from thermodynamics. Is it not a postulate of the Kinetic Molecular Theory.
<u>"1. Average Kinetic Energy of the system is a measure of the temperature of the system."</u>
Postulate of Kinetic Molecular Theory
- The average kinetic energy of the system is measured by its temperature and nothing else
<u>"2. Energy is conserved in the collisions between gas molecules.."</u>
Postulate of Kinetic Molecular Theory
- All collisions between gas molecules are perfectly elastic, meaning no energy is lost
<u>"3. Energy can either be destroyed or created. Its goes from one form to another.</u>
<u /> NOT a Postulate of Kinetic Molecular Theory
- Related to Conservation of Energy from thermodynamics
<u>"4. Gases travel in straight line until they collide with other gas molecules"</u>
Postulate of Kinetic Molecular Theory
- All gas molecules will travel in a straight line until they collide with other gas molecules or some object (e.g. a container)
