Answer:
Explanation:
First, find the mass of empirical formula, CH. 12.01 g/mol is for carbon, and 1.008 g/mol is for hydrogen. 12.01+1.008=13.018 G/mol CH. Divide 78.110 G/mol by 13.018 g/mol. You get approximately 6. Multiply that by the subscript of each element. 6(CH)=

4) is correct
This is because water is polar and it will mix with a polar solvent. A good rule for remembering the behavior of non-polar and polar compounds when it comes to being miscible is that "like dissolves like."
By using Kp formula:
Kp = Kc RTΔn
when Kc = 4.63x10^-3
R = 0.0821
T= 527 + 273 = 800 K
Δn = moles of products - moles of reactants = 2-1 = 1
by substitution:
Kp= 4.63x10^-3 * 0.0821 * 800 = 0.304
from ICE table:
COCl2(g) → CO(g) +Cl2(g)
initial 0.760 0 0
change -X +X +X
final (0.760-X) +X +X
by substitution:
Kp = P(CO)*P(Cl2) / p(COCl2)
4.63x10^-3 = X*X / (0.76- X)
∴X = 0.057
∴P(CO) = 0.057
P(Cl2) = 0.057 atm
and P(COCl2) = 0.760-0.057 = 0.703 atm
