The image of the structure is attached in the image below.

<u>Answer: </u>The correct option is a.) 4-methyl-3-phenyl-3-pentenoic acid

<u>Explanation:</u>

Carboxylic acids are a type of functional group in organic chemistry that have the symbol '-COOH'. A suffix used for this functional group is '-oic acid'.

To name a compound, first look for the longest possible carbon chain.

As in the image attached below, the longest carbon chain has 5 carbon atoms. Thus, the prefix used will be 'pent-'

Also, a methyl substituent is present at the 4th position, a phenyl substituent is located at the 3rd position.

A double bond is also present at the 3rd position and a suffix '-ene' is used.

Hence, the IUPAC name for the given compound is 4-methyl-3-phenyl-3-pentenoic acid.

Sholpan [36]

The number of mole of ammonium ion, NH₄⁺ in the solution is 0.175 mole

We'll begin by calculating the number of mole of NH₄NO₃ in the solution. This can be obtained as follow:

Volume = 125 mL = 125 / 1000 = 0.125 L

Molarity = 1.40 M

Mole = Molarity x Volume

Mole of NH₄NO₃ = 1.40 × 0.125

Finally, we shall determine the number of mole of ammonium ion, NH₄⁺ in the solution. This can be obtained as follow:

NH₄NO₃(aq) —> NH₄⁺(aq) + NO₃¯(aq)

From the balanced equation above,

1 mole of NH₄NO₃ contains 1 mole of NH₄⁺

Therefore,

0.175 mole of NH₄NO₃ will also contain 0.175 mole of NH₄⁺

Thus, the number of mole of ammonium ion, NH₄⁺ in the solution is 0.175 mole

You have a gas stored in a rigid container (fixed volume). Explain the relationship between a decrease in temperature, collision

alexandr1967 [171]

Answer:

A decrease in temperature would decrease kinetic energy, therefore decreasing collisions possible.

Explanation:

A gas at a fixed volume is going to have collisions automatically. If you decrease the temperature (same thing as decreasing kinetic energy) you are cooling down the molecules in the container which gives them less energy and "relaxes" them. This decrease in energy causes them to move around much slower and causing less collisions, at a much slower rate. In a perfect world, these collisions do not slow down the molecule but we know that they do, just a very very small unmeasurable amount.
