PV = nRT. If P = 1 atm, V = 5.0 liter, R = 0.0821 L.atm/mol.K, and T = 293 K; what is the value of n?
Leya [2.2K]

Answer:

n = 0.207 mole

Explanation:

We have,

P = 1 atm

V = 5 liter

R = 0.0821 L.atm/mol.K

T = 293 K

We need to find the value of n. The relation is as follows :

PV = nRT

Solving for n,

n=\dfrac{PV}{RT}\\\\n=\dfrac{1\times 5}{0.0821 \times 293}\\\\n=0.207\ \text{mol}

So, the value of n is 0.207 mol.

Why is the moisture of cirrus clouds mostly in the solid state
MariettaO [177]

Answer:

Wind is the horizontal movement of air, transporting energy transferred from the earth's surface as sensible and latent heat. Sensible heat is transferred by the processes of conduction and convection. Conduction transfers energy within a substance, and convection transfers energy through the vertical movement of the heated substance. Latent heat is the transfer of energy by transforming the substance itself. As you recall, water has the ability to exist as liquid, gas or solid. The transformation from liquid to gas is called evaporation; the reverse process, from gas to liquid, is called condensation; from liquid to solid is known as solidification (freezing); and from solid to liquid, fusion (melting). Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds.

How many moles of carbon are in 5.2 moles of C7H18?
bulgar [2K]
There is a shortcut to this Chem question. simply look at this problem as if it were a cooking recipe. you have 7 parts Carbon and 18 Parts Hydrogen for a total of 25 parts. Simply divide 5.2 by 25 then multiply by 7 to get your answer.
(5.2/ 25) 7 = 1.456 moles

Write a conversion factor that converts between moles of calcium ions in calcium phosphide, Ca3P2, and moles of Ca3P2.
cricket20 [7]

The conversion factor between moles of calcium ion and moles of Ca_3P_2 in  Ca_3P_2 would be 3 to 1.

<h3>Mole fraction</h3>

Ca_3P_2 if formed from 3 carbon atoms and 3 phosphate atoms according to the equation:

3Ca + 2P --- > Ca_3P_2

Thus, there are 3 moles of calcium in every 1 mole of  Ca_3P_2.

The conversion factor between moles of calcium and moles of  Ca_3P_2 will. therefore, be 3 to 1 or simply 3:1.
