We have the following chemical reaction:

P₄ + 10 Cl₂ → 4 PCl₅

<u>Identifying the limiting reactant.</u>

mass of  P₄ = 28 g

mass of Cl₂ = 53 g

number of moles = mass / molecular weight

number of moles of P₄ = 28 / 124 = 0.226 moles

number of moles of Cl₂ = 53 / 71 = 0.746 moles

From the reaction we see that 1 mole of P₄ will react with 10 moles of Cl₂ so 0.226 moles of P₄ will react with 2.226 moles of Cl₂, but we have only 0.746 moles of Cl₂. So the limiting reactant will be Cl₂.

<u>Part B</u>

From the previous calculations we know that 28 g of P₄ are equal to 0.226 moles moles of P₄.

Now, knowing the chemical reaction, we devise the following reasoning:

if        1 mole of P₄ produces 4 moles of PCl₅

then  0.226 moles of P₄ produces X moles of PCl₅

X = (0.226 × 4) / 1 = 0.904 moles of PCl₅

<u>Part C</u>

From the previous calculations we know that 53 g of Cl₂ are equal to 0.746 moles moles of Cl₂.

Now, knowing the chemical reaction, we devise the following reasoning:

if         10 moles of Cl₂ produces 4 moles of PCl₅

then   0.746 moles of Cl₂ produces X moles of PCl₅

X = (0.746 × 4) / 10 = 0.298 moles of PCl₅

Suppose the total number of molecules is x 
Number of molecules of chair form is 6.42/100 x
Number of molecules of boat form is 93.58/100 x
Kc = \frac{(0.9358x)}{(0.0642x)} = 14.6

Elena L [17]
The correct answer is D. A solid has a high to very high melting point, great hardness , and poor electrical conduction, this is a covalent network solid. This is because of the large amount of energy required to break these bonds, the said properties are exhibited by these solids.

For an atom’s electrons, how many energy sublevels are present in the principal energy level n = 4?
defon
"n" represents principal energy level or principal quantum number. Principal energy levels are then subdivided into sublevels. The level of principal energy level is always equal to number of sublevels. Therefore if <span>principal energy level</span> = 4, then there are also 4 sublevels present, namely: 4s, 4p, 4d and 4f sublevels.
