What is the ratio of effusion rates of krypton and neon at the same temperature and pressure?
egoroff_w [7]
The formula we use would be the graham's law. We do as follows:

<span>E_Kr / E_Ne = sqrt ( M_Ne / M_Kr) 
</span>
<span>= sqrt ( 20.1797 g/mol / 83.798 g/mol ) </span>
<span>= sqrt (0.24081) </span>
<span>= 0.4907
</span>
Hope this answers the question. Have a nice day.

Using standard free energy of formation values given in the introduction, calculate the equilibrium constant kp of the reaction
WINSTONCH [101]

d G = 2 (dG NOCl) - 2 (dG NO)

= 2 * 66.08 - 2 * 87.6 = -43.04 kJ /mol

dG = - 2.303 RT log K

-43.04 = - 2.303 RT log K

7.54 = log K

K = 3.42 * 10^7

Kp = k (RT)^dn

d n = 2 - 1 -2 = -1

Kp = (3.42 * 10^7) (8.314 * 298)^-1

Kp = 1.31 * 10^4

How many atoms are in 5 GRAMS of Fe2O3
Llana [10]

There are two iron atoms and three oxygen atoms in each molecule of Fe2O3. So that's five atoms per molecule.

One mole of any molecular substance contains <span>6.02×1023</span> molecules. Since there are two iron atoms in each of the molecules we're considering, there will be <span><span>(6.02×1023)</span>⋅2=1.204×1024</span> iron atoms in a whole mole of them.

But we're considering 0.550 mol, so multiply by 0.550:

<span>n=(0.550</span> mol<span>)⋅<span>(3.01×1024</span></span> atoms/mol<span>)=6.62×1023</span> iron atoms.

What will knowledge of chemistry enable you to do?
Fofino [41]
Understanding chemistry and its principles enables us to predict and understand various properties of substances. For example, because we know that ionic bonds are very strong and difficult to break, we know that any substance that has these bonds will have a high melting point, because melting is a process that requires the intermolecular bonds present in the solid state to be broken. This can be applied to table salt, sodium chloride, which has an ionic structure and a melting point of almost 800 degrees Celsius. Similarly, many other properties and characteristics may be predicted using concepts of chemistry.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the
Alchen [17]

In the first law of thermodynamics, it states when heat is converted into energy, where as the total energy in the room could transform into another but can never be created or destroyed. If you release 258J of energy in the room, 258J would also be removed from the food according to the isolating system.

Your answer would be 258J.
