i don't need these solved I just need the steps to solve it and. what these problems in chemistry would be called so I can look
wolverine [178]

The answers are as follows,

1. 4.71 L,

2. 3.29 L,

3. 1634.6 torr

<u>Explanation:</u>

All the above problems can be sorted out using the Boyle's law represents the relationship between the volume and pressure.

It can be expressed as follows,

                      P1V1 = P2V2

Rearranging the above expression, we get,

                     $ V2 = \frac{P1V1}{V2}

1) The first case can be solved as,

     $V 2=\frac{921 \mathrm{mm} \mathrm{Hg} \times 3.89 \mathrm{L}}{760 \mathrm{mm} \mathrm{Hg}}=4.71 \mathrm{L}

2) The second case can be solved as,

       $V 2=\frac{25 L \times 600 \text { torr}}{4560 \text { torr}}=3.29 L

3) The third case can be solved as,

     $P 2=\frac{7.43 L \times 1100 \text { torr}}{5 L}=1634.6 \text { torr}

Thus the answers for all the three cases are found as,

1. 4.71 L,

2. 3.29 L,

3. 1634.6 torr respectively

What ratio of nitrogen and hydrogen molecules would result in no left-over reactants? Explain your answer.
madam [21]

A ration, Nitrogen to Hydrogen, of 1 : 3 would result in no left-over reactants

Explanation:

This is because Nitrogen and Hydrogen would react to form ammonia as shown in the following reaction below;

N₂ (g) + 3H₂ (g) → 2NH₃ (g)

For every mole of Nitrogen gas, you would require 3 moles of Hydrogen gas. This way they would react to form Ammonia with no leftover reactants.
