Answer:
The formation of natural diamonds requires very high temperatures and pressures. These conditions occur in limited zones of Earth's mantle about 90 miles (150 kilometers) or more below the surface, where temperatures are at least 2000 degrees Fahrenheit (1050 degrees Celsius) [1].

google, education is important, dont cheat, etc. its not good. u got this, never give up <3
Answer:
Condenser
Explanation:
Condenser is highly efficient when dealing with the vapors of the product are need to be liquified. It is mostly automated and regularly condenses the incoming vapors into liquid. It is very easy to use. All we have to do it to attach incoming and outgoing flow pipes and constantly monitor the flow of cold water through the condenser. It is made up of special kind of PYREX glass so that it won't break when dealing with steam.
It is a neutralization reaction.
Answer:
warm water is denser than cold water
Explanation:
Answer:
A) homotopic and B) enantiotopic
Explanation:
Protons chemically equivalent are those that have the same chemical shift, also if they are interchangeable by some symmetry operation or by a rapid chemical process.
The existence of symmetry axes, Cn, that relate to the protons results in the protons being homotopic, that is chemically equivalent in both chiral and aquiral environments.
The existence of a plane of symmetry, σ, makes the protons related by it, are enantiotopic and these protons will only be equivalent in an aquiral medium; if the medium is chiral both protons will be chemically NOT equivalent. The existence of a center of symmetry, i, in the molecule makes the related protons through it enantiotopic and therefore chemically only in the aquiral medium.
Diastereotopic protons cannot be interconverted by any symmetry operation and they are different, with different chemical displacement.
