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

What is the mass in grams of a single formula unit of silver chloride, AgCI? A) 4.21 x 1021 g B) 8.61 x 10258 C) 1.66 x 10-248 D

bekas [8.4K]

Answer: D) $2.38*10^-^2^2$ g

Explanation: The question asks to convert formula unit to grams. It is a unit conversion problem.

1 mole equals to Avogadro number of formula units. So, to convert the given number of formula units to moles, we need to divide by the Avogadro number. After this, we do moles to grams conversion and for this the moles are multiplied by the molar mass of the compound. Molar mass of AgCl is 143.32 gram per mol.

$1FormulaUnitAgCl(\frac{1mol}{6.022*10^2^3formulaUnits})(\frac{143.32g}{1mol})$

= $2.38*10^-^2^2$ g

So, the correct option is D) $2.38*10^-^2^2$ g

Select the correct answer.

matrenka [14]

Answer:

At equilibrium the rate of the forward reaction is equal to the rate of the backward reaction.

When the product of a reaction at equilibrium is increased the equilibrium will shift left or to the reactant side. As a result the excess product will get converted to reactant. This is in accordance to Le Chatelier's principle.

Le Chatelier's principle states that when a system is subjected to stress the equilibrium will shift in a direction to minimize effect of the stress.

Thus the products added to the system at equilibrium will make the equilibrium shift to the reactant side, the rate of the reverse or backward reaction will increase.

You are performing a titration of a triprotic acid, when you spill water on your lab notebook. you can read that: pka 1 = 1.40,

eimsori [14]

According to the PH formula:
PH= Pka +㏒ [strong base/weak acid]
when we have PH at the first equivalence =3.35 and the Pka1 = 1.4
So, by substitution, we can get the value of ㏒[strong base / weak acid]
3.35 = 1.4 + ㏒[strong base/ weak acid]
∴㏒[strong base/weak acid] = 3.35-1.4 = 1.95
to get the Pka2 we will substitute with the value of ㏒[strong base/ weak acid] and the value of PH of the second equivalence point
∴Pk2 = PH2 - ㏒[strong base/ weak acid]
= 7.55 - 1.95 = 5.6
