1. You watch water falling from the top of a waterfall to the bottom. How would you characterize this physical phenomenon in ter

ms of spontaneity? What if you wanted to move the water from the bottom of the falls to the top—how would you characterize that reaction?

Well the reason why the water valve was because of the force of gravity. Without the force of gravity the water would have flown so if you had to try to move the water up the waterfall you would have to fight the force of gravity

Answer:

Water falling from the top of the fall to the bottom is a spontaneous process. Raising water from the bottom to the top of the waterfall is a non-spontaneous process.

Explanation:

Water falling from the top of the fall to the bottom is a spontaneous process. The Earth’s gravity is pulling every object to the centre of the Earth. So it is difficult to overcome Earth’s centre of gravity and raise the water from the bottom to the top of the fall. Raising water from the bottom to the top of the waterfall is a non-spontaneous process.

Explain why a random copolymer is obtained when 3,3-dimethyl-1-butene undergoes cationic polymerization.
dezoksy [38]

Solution :

In the field of chemistry, the cationic polymerization is a kind of the chain growth polymerization where the cation initiator transfers the charge to the monomer and makes it more reactive. This kind of polymerization reaction is very sensitive to the temperature. With increase in temperature, the molecular weight as well as the reaction rate decreases rapidly.

Thus in the cationic polymerization of the 3,3-dimethyl-1-butene, the carbonation intermediate is formed and it rearranges itself. The attack o the 2nd alkene ca take place both the carbonations, so that random copolymer is formed.

For single bonds between similar types of atoms, how does the strength of the bond relate to the sizes of the atoms? Explain.
uysha [10]

When comparing single bonds between atoms of comparable types, the stronger the bond is, the bigger the atom, the weaker it is.

The length of the X-H bond lengthens while the strength of the bond shortens with increasing halogen size (F-H strongest, I-H weakest). When comparing single bonds between atoms of similar sorts, the larger the atom, the weaker the bond. It can be explained by the fact that less energy is required to break the bond the bigger the atom's atomic size. The force of attraction from the nucleus to the outermost orbit will be less for iodine since it has a larger atom than the other elements in the group.

Which of these safety features aims to keep nuclear radiation contained
rewona [7]

The safety feature aimed at keeping nuclear radiation contained is steel-reinforced concrete.

<h3>What is nuclear power plant?</h3>

A nuclear power plant is a building with reactors that contain controlled nuclear reactions to produce energy.

Nuclear power plants are able to generate warm water by using atomic properties of matter  (i.e.,m the process of nuclear fission), which is in turn converted into steam to move turbines.

The walls of nuclear power reactors are composed of steel-reinforced concrete in order to avoid radiation release.

In conclusion, the safety standard property that maintains nuclear radiation contained is steel-reinforced concrete.

The first step of electrophilic aromatic substitution involves the formation of the arenium ion intermediate.
Anastaziya [24]

Answer:

True

Explanation:

Aromatic compounds undergo substitution rather than addition reactions because the aromatic structure is maintained.

Electrophilic aromatic substitution begins with attack of the electrophile on the aromatic ring to yield a delocalized intermediate called the arenium intermediate. Loss of hydrogen from this intermediate yields the final product.
