A gas vessel is charged with a mixture of pcl3(g) and cl2(g), which is allowed to equilibrate at 450 k. at equilibrium the parti

al pressures of the three gases are ppcl3 = 0.132 atm, pcl2 = 0.190 atm, and ppcl5 = 1.67 atm. (a) what is the value of kp at this temperature?

Answer is: Kp = 66,586.
Chemical reaction:  PCl₃(g) + Cl₂(g)  ⇔ PCl₅(g).
Kp - equilibrium constants expressed in terms of partial pressures of gases.
Kp = p(PCl₅) ÷ p(PCl₃) · p(Cl₂). p-partial pressure.
Kp = 1,67 atm ÷ 0,132 atm · 0,190 atm
Kp = 66, 586 1/atm. Favors product.

Why is it important to know where a resource, that you're using, is renewable or nonrenewable?
NemiM [27]

Answer:

It is important to know if a resource is renewable or non-renewable because renewable resources are self-sustaining (unlike non-renewable resources). If a non-renewable resource is used too often, that resource may eventually become non-existant. This can also happen to renewable resources, but it is more difficult.

How many liters of plasma are present in 8.5 pints?
stellarik [79]

Answer:

there are 4.0205 Litres of plasma in 8.5 pints

Explanation:

Recall that:

1 quart qt = 2 pints pt  and 1 quart = 946 mL

∴ two pints will contain 946 mL

and one pint will be = 946 mL/2

=  473 mL

Similarly, 8.5 pints will contain 473 mL × 8.5 = 4020.5  mL

We know that :

1000 mL = 1 Litres

Hence 4020.5 mL = (4020.5 /1000)L

= 4.0205 Litres

Therefore, there are 4.0205 Litres of plasma in 8.5 pints

How does atomic radius change from top to bottom in a group in the periodic table?
suter [353]
The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.
