Answer:
Limiting reactant: Cl2.
Max mass of PCl3 = 41.44 g.
P4 leftover = 5.51 g.
Explanation:
Hello!
In this case, since the undergoing chemical reaction is:
In order to compute the maximum amount of PCl3, it is necessary to compute the grams of this product produced by each reactant, just as shown below, whereas molar masses and mole ratios are used:
Thus, since chlorine gas yields fewer grams of PCl3 than P4 we infer Cl2 is the limiting reactant and 63.41 grams of PCl3 product are yielded.
Finally, for the excess reactant, we see a difference of 63.41-41.44=21.97g, so we can compute of the leftover of P4 as follows:
Best regards!
Answer:
If I'm correct the answer is C. Stay a gas but my gut is telling me the answer is B. turn to a liquid
The answer would be, D. because ive taken the test.
Answer:
P(total) = 6.7 atm
Explanation:
Given data:
Partial pressure of N₂ = 3.5 atm
Partial pressure of O₂ = 2.8 atm
Partial pressure of Ar = 0.25 atm
Partial pressure of He = 0.15 atm
Total pressure = ?
Solution:
According to the Dalton law of partial pressure,
"The total pressure inside the gas cylinder having mixture of gases is equal to the sum of partial pressures of individual gas present in it"
Mathematical expression:
P(total) = P₁ + P₂ + P₃ + .........Pₙ
Now we will determine the total pressure of given gases.
P(total) = P₁ + P₂ + P₃ + P₄
P(total) =P(N₂) + P(O₂) + P(Ar) + P(He)
P(total) = 3.5 atm + 2.8 atm + 0.25 atm + 0.15 atm
P(total) = 6.7 atm
