Answer: D. To decrease the total moles of gas in the system

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

when the pressure is increased, , the volume will decrease according to Boyle's Law. Now, according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place.

As the pressure is directly proportional to the number of moles of gas molecules. So, the equilibrium will shift in a direction where the total moles of gas are decreasing.

Thus the correct answer is to decrease the total moles of gas in the system.

6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume
alex41 [277]

Answer:

1.71atm

Explanation:

The following were obtained from the question:

V1 (initial volume) = 6L

P1 (initial pressure) = 1atm

V2 (final volume) = 3.5L

P2 (final pressure) =?

Using the Boyle's law equation:

P1V1 = P2V2, the final pressure can be obtained as follow:

P1V1 = P2V2

1 x 6 = P2 x 3.5

Divide both side by 3.5

P2 = 6/3.5

P2 = 1.71atm

The final i.e the new pressure inside the piston is 1.71atm

Which one of the following groups of chemical compounds is composed entirely of organic compounds?
guajiro [1.7K]

Answer:

D

Explanation:

Organic compounds are chemical compounds which usually contains one or more atoms of carbon, hydrogen, oxygen and sometimes nitrogen or sulphur. Carbon and hydrogen are the main element that is contained in most organic compounds.

Option A is wrong because calcium phosphate is not an organic compound, although all the other compounds in the option are organic compounds.

Option B is wrong because calcium chloride is not an organic compound

Option C is wrong also as calcium sulphate is not an organic compound

Option D is correct as all are organic compounds

5.4 When looking down the C{{TOP-HAT-MATH-TOKEN-0}}-C{{TOP-HAT-MATH-TOKEN-1}} bond in 2,3-dimethylbutane, what is the most stabl
AURORKA [14]

Answer:

The most stable conformer would be the anti-conformer when the substituent methyl groups are farthest away from each other.

Explanation:

Isomers are chemical compounds with the same molecular formula but with different molecular structures.

Conformers are a special type of isomers that produce different structures when the substituents of a Carbon-Carbon single bond (C-C) are rotated.

In 2,3 dimethyl butane, the substituent methyl groups are located around the second and third Carbon to Carbon single bond.

To achieve a stable configuration, the methyl group substituents need to be as far apart as possible (that is, in an anti-position) to minimise repulsion.

The closer the methyl groups are to each other, the more they repel each other and the more unstable the conformer becomes.
