A gas that exerts a pressure of 537 torr in a container with a volume of 5.30 L will exert a pressure of 255 torr when transferr
ArbitrLikvidat [17]

Answer:- The gas needs to be transferred to a container with a volume of 11.2 L.

Solution:- From Boyle's law. "At constant temperature, Volume is inversely proportional to the pressure."

It means, the volume is decreased if the pressure is increased and vice versa.

Here, the Pressure is decreasing from 537 torr to 255 torr. So, the volume must increase and calculated by using the equation:

P_1V_1=P_2V_2

Where, P_1 is initial pressure and P_2 is final pressure. Similarly, V_1 is initial volume and V_2 is final volume.

Let's plug in the values in the equation:

(537 torr)(5.30 L) = (255 torr)(V_2)

V_2=(\frac{537 torr*5.30 L}{255 torr})

V_2 = 11.2 L

So, the new volume of the container needs to be 11.2 L.

Which of the following factors would reduce the yield of a reaction?
NikAS [45]

The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.

<h3>What is a Chemical reaction?</h3>

This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.

A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.

When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

What is the molarity of a solution with 130g of CoCl2 in 1/2 liter? (can you show the steps please)
Elden [556K]

Answer:

2M

Explanation:

M=mol/L

1. Find moles of CoCl2

mass of substance/molar mass = 130/129.833 = 1.001 mol

3. Substitute in molarity equation

M=(1.001/0.5)

M= around 2M
