According to the Arrhenius theory, when a basedissolves in water it produces
(1) CO3 2– as the only negative ion in solution
(2) OH– as the only negative ion in solution
(3) NH4 + as the only positive ion in solution
(4) H+ as the only positive ion in solution

Answers

Answer 1
Answer: According to Arrhenius Theory of acids and bases, when a base dissolves in water, the only negative ion produced is OH-.

Therefore, (2) OH– as the only negative ion in solution is the correct answer.

Hope this would help~

Distillation is used to separate _____.a. heterogeneous mixtures
b. suspensions
c. colloids
d. solutions

Answers

Distillation is the process of separating homogeneous mixtures -and  a solution is a homogenous mixture, so this is the correct answer!

A homoogeneous mixture is a mixture in which the elements are mixed so well, that the mixture has a similar composition in all its parts. A heat can be applied to this mixture then to separate the parts - this is destination!

The answer is A) heterogeneous mixtures, look up how a heterogeneous mixture is separated and it will tell you distillation. Have a nice day and good luck on the rest of your work

What is the molarity of a solution made with 298g of potassium chloride dissolved in enough water to make 2L of solution?

Answers

The molarity of the solution made by dissolving 298 g of KCl in enough water to make 2 L of the solution is 2 M

  • We'll begin by calculating the number of mole in 298 g of potassium chloride, KCl. This can be obtained as follow:

Mass of KCl = 298 g

Molar mass of KCl = 39 + 35.5 = 74.5 g/mol

Mole of KCl =?

Mole = mass / molar mass

Mole of KCl = 298 / 74.5

Mole of KCl = 4 moles

  • Finally, we shall determine molarity of the KCl solution. This can be obtained as follow:

Mole of KCl = 4 moles

Volume = 2 L

Molarity of KCl =?

Molarity = mole / Volume

Molarity of KCl = 4 / 2

Molarity of KCl = 2 M

Therefore, the molarity of the KCl solution is 2 M.

Answer:

2 M

Explanation:

The equation for molarity is "M = moles/liters"

Potassium chloride's atomic mass is 74.55, meaning one mole of KCl is equal to 74.55g. In the equation, 298g of KCl is being used. To find out how many moles this is, multiply 298g of KCl by (1 mol/74.55g of KCl) to get 4.0 moles. Now you can use the equation for molarity.

M = 4.0 moles/2 Liters

Which of the following answer choices best describes J. J. Thomson's plum-pudding model?An atom is surrounded by a firm outer shell and contains positively charged particles in its core.An atom is surrounded by a firm outer shell and contains negatively charged particles in its core.An atom consists of positively charged matter that contains negatively charged particles.An atom consists of negatively charged matter that contains positively charged particles.

Answers

The statement that best describes J. J. Thomson's plum-pudding model is; an atom consists of positively charged matter that contains negatively charged particles.

The model of J. J. Thomson looked at the atom merely as a ball of positive charges into which negative charges were embedded.

This model was propounded by J. J. Thomson in the year 1897. This model began the journey into empirical observation of the structure of the atom.

Thompson further carried out his experiments using a cathode ray tube and propounded the model shown in the image attached to this answer.

Freezing requiresa. the removal of energy.
b. the absorption of energy.
c. no energy change.

Answers

Answer:

The correct answer is option a. the removal of energy.

Explanation:

Hello!

Let's solve this!

Freezing is a process by which a lot of heat is lost, this loss of heat leads to a loss of energy as well. It means that energy is eliminated so that heat loss occurs.

Therefore the correct answer is option a. the removal of energy.

How does an element differ from a compound

Answers

Elements are one , but compound is elements all together to form something.


-_- Compounds n Elements -_-


A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds.

When the elements are joined, the atoms lose their individual properties and have different properties from the element they are composed Of .
