Which statement describes an alternate theory of acids and bases?(1) Acids and bases are both H+ acceptors.
(2) Acids and bases are both H+ donors.
(3) Acids are H+ acceptors, and bases are H+ donors.
(4) Acids are H+ donors, and bases are H+ acceptors.

Answers

Answer 1

Answer:

Answer: Option (4) is the correct answer.

Explanation:

According to Bronsted and Lowry, acids are the species which can donate hydrogen or $H^(+)$ ions.

Whereas bases are the species which can accept hydrogen or $H^(+)$ ions.

Thus, we can conclude that the statement acids are $H^(+)$ donors, and bases are $H^(+)$ acceptors describes an alternate theory of acids and bases.

Answer 2

Answer: The answer is (4) Acids are H+ donors, and bases are H+ acceptors. This constitutes the Bronsted-Lowry theory of acids and bases.

An evaporation-crystallization process is used to obtain solid potassium sulfate from an aqueous solution of this salt. The fresh feed to the process contains 19.6 wt% K₂SO₄. The wet filter cake consists of solid K₂SO₄ crystals and a 40.0 wt% K₂SO₄ solution, in a ratio 10.0 kg crystal/kg solution. The filtrate, also a 40.0 wt% K₂SO₄ solution, is recycled to join the fresh feed. Of the water fed to the evaporator, 45.0% by weight is evaporated. The evaporator has a maximum capacity of 175. kg water evaporated/s. a) Assume the process is operating at maximum capacity. Draw and label a flowchart and do the degreeof-freedom analysis for the overall system, the recycle-fresh feed mixing point, the evaporator, and the crystallizer. b) Calculate the maximum production rate of solid K₂SO₄, the rate at which fresh feed must be supplied to achieve this production rate, and the recycle ratio kg/h recycled stream to kg/h fresh feed stream.

what volume of a 0.716 m kbr solution is needed to provide 25.5 g of kbr? 35.7 ml 14.7 ml 299 ml 0.299 ml 153 ml

Answers

Answer:

$\huge{ \boxed{299 \: ml}}$

Explanation:

The volume of KBr required can be found by using the formula;

$v = (m)/(M * c)$

c is the concentration in M , mol/dm³ or mol/L

v is the volume in L or dm³

m is the mass in grams

M is the molar mass in g/mol

From the question;

m = 25.5 g

c = 0.716

Molar mass (M) of KBr = 39 + 79.9 = 118.9 g/mol

$\therefore \: v = (25.5)/(118.9 * 0.716) \n = 0.299 \: l \n \n \text{but} \: 1 \: l \: = 1000 \: ml \n \therefore0.299l \: = (0.299)/(1) * 1000 \: ml \n = 299 \: ml \n \therefore \: v = 299 \: ml$

a hydrogen atom has one proton, two neutrons, and no electrons. Is this atom an ion? Explain your answer.

Answers

An atom is a neutral species. Hence, it must have same number of electrons and protons. On other hand, ions have charge. Hence, number of protons and electrons are not same.

In present case, hydrogen has one proton, two neutrons, and no electrons. This signifies that overall charge of species is +1. Hence, it is an ion.

yes this is an ion because an ion is defined as an element that has gained or lost electrons. There should be 1 electron is Hydrogen but since there aren't any that means that it is an ion which is commonly written as H^+.

Explanation:

A salt is best described as a compound that is formed from the reaction betweenan acid and a base.
a strong acid and a weak acid.
a strong base and a weak base.
an acid and water.

Answers

The right answer is A (strong acid with strong base).

The reaction of an acid with a base to produce salt and water alone is called a neutralization reaction.

A salt is a compound formed following a replacement of the hydrogen ions (H +) of an acid with a basic radical during a reaction.

A normal salt is formed by the complete replacement of the H + of an acid (example Na2CO3).

while an acidic salt is formed by the incomplete replacement of the H + of an acid (eg NaHCO3).

What is the mole ratio of NaOH to Al(OH)3

What is mole ratio?

The ratio of the mole quantities of just about any two compounds present inside a chemical reaction is known as the mole ratio. In many chemical situations, mole ratios are employed as conversion factors among products and reactants.

In a balanced chemical equation, the coefficients in front of the formulae can be used to determine the mole ratio. A reaction's product yield may be predicted using mole ratios, as can the quantity of reactant required to produce a specific amount of result.

Al(OH) $_3$ + NaOH →NaAlO $_2$ + 2 H $_2$ O
