What is the molarity of a solution that contains 612 grams of CaCl2 in 3.04 liters of solution?1.81 M
201 M
5.52 M

Answers

Answer 1

Answer:

1. There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. The concentration of the solution is calculated as follows:

Molarity = 612 g (1 mol / 110.96 g) / 3.04 L

Molarity = 1.81 M

Answer 2

Answer:

1.81 M is the polarity of a solution that contains 612 grams of CaCl2 in 3.04 liters of solution.

The process of boiling a mixture so that one part will evaporate, then cooling or condensing the evaporated liquid, and finally collecting the cooled liquid, is known asa. settling.
b. filtration.
c. distillation.
d. evaporation.

Answers

The answer is C. Distillation. Distillation is a common process for separating liquid mixtures by using the principle of volatility and boiling point. For a liquid mixture with two liquid components A and B, A will have a lower boiling point or higher volatility than B. By boiling the mixture at the boiling point of component A, only component A will evaporate from the mixture. The evaporated gas will then be cooled to condense component A back to a liquid.

The answer would be C. :))

Hydrogen has three isotopes 1H, 2H, and 3H. What is the difference between these three isotopes?

Answers

The main difference between the 3 isotopes of hydrogen are the number of neutrons in the nucleus. Hydrogen has no neutrons, Deuterium has one neutron, and tritium has two neutrons. All three have one proton and one electron.

Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.

Answers

Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.

There is no isomer of CH3OH or methanol because it contains only one carbon atom. And also, the structure is tetrahedral, having four substances attached to the carbon atom.

Technician A says that a soldering gun must be energized for several minutes before it warms up to the melting point of solder. Technician B says that a soldering torch is heated by burning butane gas. Who is right

Answers

Answer:

Both are right

Explanation:

A constant heat must be supplied for several minutes to soldering gun to overcome the melting point of solder. A butane torch is a type of soldering device powered (energised) by the burning of butane gas to melt and solder common metals

Which substance can be decomposed by chemical means?(1) ammonia (3) phosphorus
(2) oxygen (4) silicon

Answers

$\boxed{\left( 1 \right){\text{ ammonia}}}$ is the substance that can be decomposed by chemical means.

Further Explanation:

The pure form of matter is defined as substance but the mixture is termed as the combination of atoms and molecules.

Classification of substances:

(a). Element

It is a type of pure substance and is the simplest form that cannot be broken down by any chemical means. Copper, iron, and aluminium are some of the examples of elements.

(b) Compound

It is composed of two or more different elements that are held together by chemical bonds. These can be decomposed into their respective constituents. Compounds have no similarity in properties with those of their constituent particles. NaCl, ${\text{C}}{{\text{O}}_{\text{2}}}$ and ${\text{N}}{{\text{H}}_3}$ are examples of compounds.

(1) Ammonia contains one nitrogen and three hydrogen atoms so it is a compound. Since compounds can be decomposed chemically, ammonia is also decomposed by chemical means.

(2) Oxygen (O) is an element so it is the simplest form in which it can exist. Therefore it cannot be decomposed by chemical means.

(3) Phosphorus (P) is an element so it is the simplest form in which it can exist. Therefore it cannot be decomposed by chemical means.

(4) Silicon (Si) is an element so it is the simplest form in which it can exist. Therefore it cannot be decomposed by chemical means.

Grade: High School

Subject: Chemistry

Chapter: Elements, compounds, and mixtures

Keywords: substance, ammonia, oxygen, phosphorus, silicon, element, compound, chemical means, decomposed, broken down, simplest form.

Final answer:

Ammonia is a compound composed of nitrogen and hydrogen, and as such, can be chemically decomposed into these elements. Oxygen, phosphorus and silicon, being elements, cannot be decomposed by chemical means.

Explanation:

In the context of chemistry, a substance can be decomposed by chemical means if it is a compound. Compounds are composed of two or more different elements and can be broken down into those elements through chemical reactions. In the given options, (1) ammonia is a compound, composed of nitrogen and hydrogen elements. Therefore, ammonia can be chemically decomposed into its constituent elements. In contrast, oxygen, phosphorus, and silicon are all elements, which means they cannot be decomposed further by chemical means.
