If a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then what happens to the temperature of the gas?

Answers

Answer 1

Answer: If a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then temperature of the gas increases twice.

Explanation:

Charles law states that at constant pressure, the volume of a gas is directly proportional to the temperature.

That is, [tex]V \propto T[/tex].

So, when a gas is pumped from a smaller container to a container that is twice the size shows that volume is increasing by 2 times and its pressure is kept the same.

Therefore,

[tex]2V \propto 2T[/tex]

This means that the temperature of the gas will also become twice its initial temperature.

Thus, we can conclude that if a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then temperature of the gas increases twice.

Which of the following results in a decrease in the entropy?
Heating ice
Increasing mass
Cooling a liquid
Dissolving salt in water

Answers

Answer:

cooling a liquid

Explanation:

Temperature is lowered and the energy of molecules, and therefore number of available configuration , is lowered

The thermal energy present in the system for the product formation is entropy. Cooling a liquid can decrease the entropy of the thermodynamic system. Thus, option C is correct.

What is entropy?

Entropy is the energy and the heat present in the reactant of the thermodynamic system that is associated with the randomness and disorder of the particle matter in the reaction system.

Entropy is dependent on factors like dissolution, temperature, randomness, kinetic energy, etc. The entropy increases with an increase in the dissolution and tempearture.

The process of cooling liquid lowers the temperature which in turn decreases the kinetic energy and randomness of the molecules and at last, the entropy decreases.

Therefore, the cooling of the liquid decreases the entropy.

Answers

The correct answer is: It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can

decrease acidity, while the carboxyl group can increase acidity.

The carboxyl functional group is acidic while the amine group is basic.

In an amino acid, there are two functional groups;

The amine groupThe carboxyl group

The carboxyl functional group is acidic because it contains a replaceable or  ionizable hydrogen ion. The amine group on the other hand is capable of accepting a proton hence it is basic.

Therefore, In a solution, the amine group can  decrease acidity, while the carboxyl group can increase acidity.

Answer:

An alcohol with three other carbons attached to the carbon with the hydroxyl group

An alcohol with two other carbons attached to the carbon with the hydroxyl group

Explanation:

If we look at 3-ethyl-3-pentanol, we will discover that the compound is a tertiary alcohol. That is, the carbon atom bearing the hydroxyl group is attached to three other carbon atoms as gown in image 1 attached.

For 2-hexanol, the carbon atom bearing the hydroxyl group is attached to two other carbon atoms hence the alcohol is a secondary alcohol. The compound is shown in image 2 attached.

What does the reducing agent do in a redox reaction? (A.P.E.X)

Answers

Answer:

The reducing agent donates electron to the oxidizing agent and gets oxidized itself

Explanation:

In an oxidation-reduction reaction, also known as REDOX reaction, one of the reactants is called OXIDIZING AGENT while the other is called REDUCING AGENT. The reducing agent is called so because it reduces another substance in the reaction.

It reduces another atom/ion by donating electrons to that atom, hence, getting oxidized itself in the process. For example, in the following reaction:

H2 + F2 → 2HF

Fluorine is getting oxidized from -2 to 0 by donating electrons to H and reducing it from +2 to 0.

A 240g hydrated sodium sulphide contains 162g of water of crystallisation. What is the correct molecular formula for this compound?
What is the answer and working

Answers

Answer:

Explanation:

First of all, 1 mol of Sodium Sulphide has molecular mass of

S = 32

Na2 = 2*23 = 46

The formula of NaS is actually Na2S. It's molecular mass = 78

How many grams of Na2S are present

Grams present = 240 - 162 = 78 which is exactly 1 mol.

The remainder is water.

The molecular mass of water = 2 + 16 = 18

162 grams of water = 162/18 = 9 mols of water.

So the correct formula is Na2S*9H20

Out of a box of 46 matches, 22 lit on the first strike. What percentage of the matches in the box did not light on the first strike?

Answers

Answer: 52.17%

Explanation:

Number of matches in the box = 46

Number of matches that lit on the first strike = 22

Number of matches that did not light on the first strike = 46 - 22 = 24

Therefore, the percentage of the matches in the box did not light on the first strike will be:

= (Number of matches that did not light on the first strike / Number of matches in the box) × 100

= 24/46 × 100

= 52.17%

Therefore, the percentage of the matches in the box that did not light on the first strike is 52.17%.

What is the density of ammonia (NH3) at 273 K and 1.00 atm?

A - 0.7601 g/L

B - 0.982 g/L

C - 1.23 g/L

D - 2.43 g/L

Answers

Answer:

0.7602 g/L

Explanation:

We'll begin by calculating the molar mass of NH₃. This can be obtained as follow:

Molar mass of NH₃ = 14.01 + (3×1.01)

= 14.01 + 3.03

= 17.04 g/mol

Finally, we shall determine the density of ammonia, NH₃. This can be obtained as follow:

Temperature (T) = 273 K

Pressure (P) = 1 atm

Molar mass of NH₃ (M) = 17.04 g/mol

Gas constant (R) = 0.0821 atm.L/Kmol

Density (D) =?

D = PM / RT

D = (1 × 17.04) / (0.0821 × 273)

D = 17.04 / 22.4133

D = 0.7602 g/L
