Nuclear Fusion is when two atoms (usually Hydrogen and helium because they are very light and abundant) are smashed together to form heavier elements and in the process releases massive amounts of energy. Nuclear Fission on the other hand is when a heavier atom is split apart at the nucleus and releases large amounts of energy and free neutrons and photons. (in the form of gamma rays)
Answer: option D. increased permeability of the membrane
Explanation:
Benzaldehyde or C6H5CHO would not undergo the aldol condensation because it does not contain an alpha-hydrogen in its structure. Aldol condensation is a type of reaction that happens between an enolate and an aldehyde or ketone leading to a alkene that has a planar structure. The lack of an alpha-hydrogen would not allow for it to undergo such process since it cannot enolize. Benzaldehyde undergoes a nucleophilic reaction known as Claisen-Schmidt condensation. It has somehow same mechanism of the aldol reaction however, the nucleophilic attack on the carbonyl happens even without the alpha-hydrogen but with an enolate that is from a ketone.
Answer:
if one goes up the other goes down
Explanation:
if supply is going up then demand is going down because less people are buying the product if demand is going up supply will go down because more people are buying the product.
Answer:
The air pressure on the inner side of the can balances that on the outside of the can.
Explanation:
Indeed the air pressure might crush a properly-sealed air-tight can during the descent. The reason is that the air pressure on the outside of the can exceeds that on the inside. The force that pushes the wall inwards exceeds the force that pushes the wall outwards. It's the pressure difference that crushes the can. However, that's not exactly the case for the "empty soft-drink can" here.
The question states that the can is already "empty." Therefore, it is quite reasonable to assume that the can was already opened. In other words, the can would no longer be air-tight. Air particles could freely enter and leave the can. As a result, when the can is brought down a mountain, air enters the can. As long as the can stays open, there would be enough air particles on the inside to balances the pressure. A pressure difference will not build up. That ensures that the can stays intact.
