Answer:

Rank of acid-base definitions from most specific to most general is-

Arrhenius, Bronsted-Lowry, Lewis

Explanation:

Arrhenius acids are those which contain H atom and furnish proton ( $H^{+}$ ) in aqueous solution. Arrhenius bases are those which contain -OH group and furnish $OH^{-}$ in aqueous solution.

Bronsted-Lowry acids are those which can donate protons. Bronsted-Lowry bases are those which can accept proton.

So clearly, Bronsted-Lowry acids are also Arrhenius acids and Bronsted-Lowry bases are also Arrhenius bases .

Lewis acids are those which can accept electrons. Lewis bases are are those which can donate electrons.

So, donating or furnishing of proton alternatively suggests acceptance of electrons. Also consumption of proton alternatively suggests donation of electrons.

Hence Lewis acid-base are also Arrhenius acid-base as well as Bronsted-Lowry acid-base.

I know that Lewis acids and bases are the most inclusive because it deals with electron acceptors and donators. so the answer must be A

An atom or ion has 41 neutrons, 36 protons, and 36 electrons. Identify the element symbol, and determine the mass number

igor_vitrenko [27]

Answer:

Element symbol: Kr.

Mass number: 77.

Charge : 0.

Explanation:

Hello,

In this case, since such substance has the same amount of protons and electrons we can infer it is an atom whose number of neutrons is defined by considering its atomic mass or mass number and atomic number which is actually equal to the number of protons and electrons (36):

$neutrons=atomic\ mass - atomic\ number$

In such a way, solving for the atomic mass we obtain:

$atomic\ mass=neutrons+ atomic\ number\\\\atomic\ mass=41+36=77$

It means that the element is krypton (Kr) as it has 36 electrons and protons so its charge is 0.

Best regards.

Which process is expected to have an increase in entropy?

olganol [36]

Answer: Option (B) is the correct answer.

Explanation:

Degree of randomness of the molecules of a substance is known as entropy. More is the kinetic energy between the molecules of a substance more will be the degree of randomness.

Therefore, when a substance is present in a gaseous state then it has the maximum entropy. In liquid state, molecules are closer to each other so, there is less randomness between them.

On the other hand, in solid state molecules are much more closer to each other as they arr held by strong intermolecular forces of attraction. Therefore, they have very less entropy.

When liquid water is formed from gaseous hydrogen and oxygen molecules then gas is changing into liquid. So, there is decrease in entropy.

When $N_{2}O_{4}$ decomposes then the reaction will be as follows.

$N_{2}O_{4} \rightarrow 2NO_{2}$

Since, 1 mole is producing 2 moles. This means that degree of randomness is increasing as both the molecules are present in gaseous form.

In formation of a precipitate, aqueous solution is changing into solid state. Hence, degree of randomness is decreasing.

Rusting of iron also leads to the formation of solid as it forms $Fe_{2}O_{3}.xH_{2}O$ .

Thus, we can conclude that decomposition of $N_{2}O_{4}$ gas to $NO_{2}$ gas is the process that is expected to have an increase in entropy.
