Why does the rate of dissolution for a gas decrease as the temperature of a solvent increases?


more space for the solute to escape


less space for the solute molecules


less space between solvent molecules


more collisions between solute and solvent molecules

Answers

Answer:

As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return back to the gas phase. As a result, the solubility of a gas decreases as the temperature increases.

How many grams of calcium are made up by 2.68 x 1023 atoms?

Answers

Answer:

Mass = 17.8 g

Explanation:

Given data:

Number of atoms of Ca = 2.68 × 10²³

Mass in gram = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

2.68 × 10²³ atoms × 1 mole  /6.022 × 10²³ atoms

0.445 mol

Mass in gram;

Mass = number of moles ×  molar mass

Mass = 0.445 mol  ×  40 g/mol

Mass = 17.8 g


1. How much heat is required to heat 22 grams of Aluminum from 15 °C to 49° C

Answers

Answer:

670.956

Explanation:

You can use this equation to solve for heat :

Q = m * c * ΔT

Q represents the heat

m represents the mass in kilograms

c is the specific heat. For aluminum, it's 897

ΔT is the change in temperature, so, 49 - 15 which is 34

Plug in the numbers and you get this :

Q = 0.022 * 897 * 34

Q = 670.956 Joules

c. a compound

Answers

I think the answer is an element

The sample here is a compound. The correct option is c.

What is a compound?

A chemical compound is a substance made up of many identical molecules that contain atoms from more than one chemical element and are held together by chemical bonds.

A molecule made up of only one element's atoms is thus not a compound.

The anode undergoes oxidation, while the cathode undergoes reduction. The species being oxidized provides the electrons.

An electrode in an electrochemical cell is referred to as an anode or a cathode depending on the direction of electron flow.

The electrode reacts with the electrolyte at the anode, producing electrons.

These electrons build up at the anode. Meanwhile, another chemical reaction occurs at the cathode, allowing that electrode to accept electrons.

Thus, the correct option is c.

A mole is a number of particles(atoms, molecules, ions)  in a substance

If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?

Answers

Answer:

160N

Explanation:

The force required to accelerate the two cars can be calculated thus:

F = m × a

Where;

F = force (Newton)

m = mass (kg)

a = acceleration (m/s²)

However, according to the question, a 50kg car is pulling a 30kg car, which means that the mass of the two cars is 50kg + 30kg = 80kg.

a = 2m/s²

F = ma

F = 80 × 2

F = 160N

Choose two different particles found in the air. Explain how they are different and how they are the same

Answers

Answer:

Dust and smoke.

Explanation:

Dust and smoke are two different particles present in the air. Dust and smoke are different from one another due to their origin. Smoke formed from burning of materials while dust refers to the soil particles lifted by the wind due to their light weight. Dust and smoke are similar to each other due to their small in size, infinite number means uncountable and light weight.

Air is a mixture of gases and consists of dust particles and water vapor. It consists of small to very large size of particles. Some of them include dust pollen, soot, and liquid droplets.

Dust and soot particles of the air are different as the soot is a fine black particle of carbon and tar. It is made by the incomplete combustion of air. While dust is fine dry particles of matter.

Hence they both differ.
