Answer:

V = 12 L

Explanation:

In order to know this, we can use the ideal gas equation which is:

PV = nRT (1)

Where:

P: Pressure

V: Volume

n: moles

R: gas constant

T: Temperature

Now, we don't know the temperature or the mole, but the problem states that the temperature is constante, so, T1 = T2 = T.

As is the same gas, we can asume the moles are the same, so n1 = n2 = n. And the gas constant is always the same value, therefore:

P1V1 = nRT

P2V2 = nRT

The general equation would be:

P1V1 = P2V2 (2)

This is known as the Boyle's law which is a relation concerning the compression and expansion of a gas at constant temperature.

So, we use the above expression and replace the data to solve for V2:

V2 = P1V1/P2

V2 = 6 * 2 / 1

<em>V2 = 12 L</em>

<em>This is the new volume, when the gas is compressed.</em>

P1V1=P2V2, so P1V1/P2=V2.
2atm x 6.0 L/1.0 atm = 12.0 L
The new volume would be 12.0 Liters

A chemist must dilute 34.3mL of 1.72mM aqueous calcium sulfate solution until the concentration falls to 1.00mM. He'll do this b
EastWind [94]

Answer:

58.9mL

Explanation:

Given parameters:

Initial volume  = 34.3mL    = 0.0343dm³

Initial concentration  = 1.72mM   = 1.72 x 10⁻³moldm⁻³

Final concentration  = 1.00mM = 1 x 10⁻³ moldm⁻³

Unknown:

Final volume  =?

Solution:

Often times, the concentration of a standard solution may have to be diluted to a lower one by adding distilled water. To find the find the final volume, we must recognize that the number of moles of the substance in initial and final solutions are the same.

   Therefore;

              C₁V₁  =  C₂V₂

where C and V are concentration and 1 and 2 are initial and final states.

        now input the variables;

                      1.72 x 10⁻³ x  0.0343 = 1 x 10⁻³  x V₂

                        V₂ = 0.0589dm³ = 58.9mL

Hund's rule states that electrons must spread out within a given subshell before they can pair
Temka [501]

Answer:

Groups 14, 15, and 16 have 2,3, and 4 electrons in the p sublevel (p sublevel has 3 "spaces" AKA orbitals), because Hunds says one in each orbital before doubling up if you had 2 electrons, group 14, they would both be in the first orbital, with 3 electrons, group 15, two in the first orbital one in the 2nd none in the 3rd. With 4 electrons, group 16, then you would have 2 in the first 2 orbitals and NONE in the 3rd.

Explanation:

If you are in group 13 you only have 1 electron so it can only be in one orbital. with group 17, you have 5 electrons, so 2 in the first 2 in the second and 1 in the 3rd, correct for Hunds rule anyway. Noble gasses, group 18, have 6 elecctrons, so every orbital is full any way you look at it.
