which changes when gases condense to form liquids

Answers

Answer 1

In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules. Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.

Which of the following notations represents an alpha particle?
A. 2 He
C.B+
В. В
D. Y

Answers

Answer:

A. 2 He

Explanation:

The notation of an alpha particle is depicted as:

                     ₂He

An alpha particles is a nucleus of 2 protons and 2 neutrons. So it is actually a Helium cation.

Alpha particles are monoenergetic and they mostly have discrete energy.

So, the mass number of the particle is 4 and atomic number is 2

The value of the rate constant for a gas phase reaction can be changed by increasing the A. temperature of the reaction vessel. B. volume of the reaction vessel. C. pressure of the reactant. D. amount of product.

Answers

Answer:

temperature of the reaction vessel

Explanation:

temperature of the reaction vessel

The value of the rate constant for a gas phase chemical reaction can be changed by increasing the: A. temperature of the reaction vessel.

What is the rate constant?

In Chemistry, rate constant is typically used with rate law to tell the reaction rate or rate of a chemical reaction that is affected by activation energy.

The rate law equation.

Mathematically, the rate law is given by this formula:

[tex]R = k[A]^x[B]^y[/tex]

Where:

k is the rate constant.A is the concentration of reactant A.B is the concentration of reactant B.

Generally, the value of the rate constant for a gas phase chemical reaction can be changed by increasing the temperature of the vessel (container) that is used in conducting the chemical reaction.

Why is the liquid oxygen machine producing less liquid oxygen than normal?

Answers

Answer:

Liquid oxygen evaporates at only a slightly higher temperature than liquid nitrogen because they have similarly low attraction between molecules. This would mean less liquid oxygen is coming out of tank 3 because some of it is evaporating as a gas instead.

The liquid oxygen machine is producing less liquid oxygen than normal because there's a low attraction between the molecules.

It should be noted that oxygen in its liquid state will take up less space. It can also be stored at a lower pressure than when it's in its gaseous state.

From the complete question, the liquid oxygen evaporates at a slightly higher temperature than the liquid nitrogen. The reason for this is due to the fact that they have similarly low attraction between molecules.

16. 160mm

17. 5600000mg

18. 10hs

19. 0.250km

20. 1daL

Explanation:

13. 1000milligram (mg) = 1gram (g)

Hence, 2000mg = 2000/1000

= 2g

14. 1 litre (L) = 1000millilitre (mL)

Hence, 5L = 5 × 1000

= 5000mL.

15. 1kilometre (km) = 1000metre (m)

Hence, 104km = 104 × 1000

= 104,000m

16. 1 centimetre (cm) = 10millimeters (mm)

Hence, 16cm = 16 × 10

= 160mm

17. 1kilogram (kg) = 1000000 milligram (mg)

Hence, 5.6kg = 5.6 × 1000000

= 5600000mg

18. 1 second (s) = 0.01 hectosecond (hs)

Hence, 1000s = 1000 × 0.01

Hence, 250m = 250/1000

In a laboratory experiment, students synthesized a new compound and found that when grams of the compound were dissolved to make mL of a diethyl ether solution, the osmotic pressure generated was atm at K. The compound was also found to be nonvolatile and a non-electrolyte. What is the molar mass they determined for this compound

Answers

The question is incomplete, the complete question is;

In a laboratory experiment, students synthesized a new compound and found that when 12.23 grams of the compound were dissolved to make 228.1 mL of a benzene solution, the osmotic pressure generated was 4.55 atm at 298 K. The compound was also found to be non-volatile and a non-electrolyte. What is the molecular weight they determined for this compound?

Answer:

287.76 g/mol

Explanation:

From;

π = M R T

M = molarity

R= gas constant

T = temperature

number of moles = π * volume/RT

number of moles = 4.55 * 228.1/1000/0.082 * 298

number of moles = 1.037855/24.436

number of moles = 0.0425 moles

Molar mass = mass/number of moles

Molar mass = 12.23 grams/0.0425 moles

Molar mass = 287.76 g/mol

A student determines the chromium(III) content of a solution by first precipitating it as chromium(III) hydroxide, and then decomposing the hydroxide to chromium(III) oxide by heating. How many grams of chromium(III) oxide should the student obtain if her solution contains 56.0 mL of 0.600 M chromium(III) nitrate?

Answers

Answer:

Explanation:

Chromium nitrate Cr( NO₃ )₂

Chromium hydroxide Cr( OH)₃

Chromium oxide ( Cr₂O₃ )

1 mole of chromium nitrate will form 1 mole of chromium hydroxide

1 mole of chromium hydroxide will form one mole of chromium oxide .

Moles of chromium nitrate in 56 mL of .6 M solution

= .056 x .6 = .336 moles

.336 moles of chromium nitrate will produce .336 moles of chromium hydroxide and .336 moles of chromium hydroxide will produce .336 moles of chromium oxide .

So chromium oxide produced = .336 moles

Molecular weight of chromium oxide = 152

.336 moles of chromium oxide is equal to

.336 x 152 grams of chromium oxide

= 51.07 grams .

A sample of compound A (a clear, colorless gas) is analyzed and found to contain 4.27g carbon and 5.69g oxygen. A sample of compound B (also a clear, colorless gas) is analyzed and found to contain 5.19g carbon and 13.84g oxygen. Are these data an example of the law of definite proportions, the law of multiple proportions, or neither? What do these data tell you about substances A and B?

Answers

Answer:

law of multiple proportions

Explanation:

The law of multiple proportions states that, if two elements A and B, combine to form more than one chemical compound. Then the various masses of one element A, which combine separately with a fixed mass of element B are in  simple multiple ratio.

We can see that the ratio of oxygen that combines with carbon in the two compounds( A and B) is 1:2. This demonstrates the law of multiple proportions.

The substances A and B must be CO and CO2 respectively.

How many atoms are in 0.580 moles of CO2?

Answers

Answer:

[tex]1.05x10^{24}atoms[/tex]

Explanation:

Hello!

In this case, according to the definition of the Avogadro's number, it is possible to realize that one molecule of CO2 contains 3 moles of atoms, one of carbon and two of oxygen, thus, we have:

[tex]0.580molCO_2*\frac{3mol\ atoms}{1molCO_2} =1.74mol\ atoms[/tex]

Then, we use the Avogadro's number to obtain:

[tex]1.74mol\ atoms*\frac{6.022x10^{23}atoms}{1mol\ atoms} \\\\1.05x10^{24}atoms[/tex]

Answers

Answer:

A value that quantifies the distance traveled by a substance relative to the distance traveled by the solvent- Retention factor

The substance to which the sample is bound at the start of an experiment- stationary phase

The substance that carries the components of a mixture- mobile phase

Explanation:

The retention is defined as a value that quantifies the distance traveled by a substance relative to the distance traveled by the solvent. It shows us how effective a solvent is at separating a mixture.

The stationary phase is the the substance to which the sample is bound at the start of an experiment. The solvent pick up the substance to be analyzed from this stationary phase. The different components of the mixture are found to move up the stationary phase at different speeds, causing them to eventually  separate from each other.

The mobile phase is the substance that carries the components of a mixture during chromatography.
