Planets that are larger in diameter, farther from the sun, and less dense then smaller planets in the solar system

They are actually known as gas giants. Gas giants are large planets that have more than 10 times the mass of Earth, they are also known as the Jovian or Outer planets . Their compositions are a majority of gases, such as hydrogen, and small amounts of rocky material (mostly at their cores). The four gas giants in our solar system are Jupiter, Saturn, Uranus, and Neptune.

are known as giant planets and they are composed of mostly gas like hydrogen gas for example. They are in contradistinction to the terrestrial planets like Mercury Venus Earth and Mars that are solid rock composed of silicate minerals.

If density usually increases with decreasing temperature, why does ice float on liquid water? Explain.

zepelin [54]

Answer:

If you continue to cool water past 4 degrees Celsius, its density starts to plummet (you can see this in the graph). At zero degrees, i.e., the temperature at which water turns into ice, the density of water is actually quite low. It turns out that ice has a lower density than water, and any object that has a lower density than the liquid form on which it’s kept (in this case, water) will be able to float!

A ____________ alkene is more stable than a ____________ alkene because they have fewer steric interactions. In an elimination r

Vesna [10]

Answer:

See explanation

Explanation:

A trans alkene is more stable than a cis alkene because they have fewer steric interactions.

⇒ In a cis alkene there is steric hindrance, because the methyl groups are on the same side of the double bond.

Because of this steric crowding, there are van der Waals repulsive forces between the electron clouds of the groups.

This decreases the stability of the cis alkene.

In an elimination reaction, a geometry where the β hydrogen and the leaving group are on opposite sides of the molecule is called anti periplanar.

⇒ 'Anti’ refers to the two functional groups lying on opposite sides of the plane of the bond

In an SN1 mechanism, a nucleophile attacks the carbocation, forming a substitution product,

⇒ The SN1 reaction is a substitution reaction, and means "nucleophilic substitution".The "1" says that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile.

while in an E1 mechanism, a base removes a β hydrogen from the carbocation, forming a new π-bond.

⇒ E1 indicates a elimination, unimolecular reaction

This implies that the rate determining step of the mechanism depends on the decomposition of a single molecular species.

.This is a classic elimination reaction – forming a new C–C(π) bond, and breaking a C–H and C–leaving group bond.

CH3CH2Br and NaOH react by an SN2 mechanism.

⇒ It's a type of reaction mechanism that is common in organic chemistry, where one bond is broken and one bond is formed, synchronously, (in one step.)

Stronger bases, like hydroxide, favor E2 reactions, whereas weaker bases, like water favor, E1 reactions

Disubstituted alkenes always have the possibility to exist as two different Diastereomer.

Diastereomer are stereoisomers that are not mirror images of one another and are non-superimposable on one another. They exist (always) in 2 forms.

Elimination reactions are regioselective, favoring formation of the more substituted and more stable alkene.

State Henry's law. Give an example of Henry's law.

ruslelena [56]

Answer:

Found this off of google, "Henry's law comes into play every time a bottle of Pepsi (or any other carbonated drink) is opened. The gas above the unopened carbonated drink is usually pure carbon dioxide, kept at a pressure which is slightly above the standard atmospheric pressure."
