By using what they know to produce new and helpful products
Answer:
0.0059mol
Explanation:
From the ideal gas equation
PV=nRT
P=Pressure
V=Volume
R=Ideal gas constant
T=Temperature
n=number of mole
P=745mmHg
760mmHg=1atm
745mmHg=0.98atm
volume of water displaced=volume of hydrogen produced=145ml=0.145L
R=0.082Latm/mol/K
T=22°C=273+22=293K
no of mole=PV/RT
=0.98×0.145/0.082×293
=0.1421/24.026
=0.0059mol

Answer:
Kp = 0.35 & Kc = 0.0075
Explanation:
PCl₅ ⇄ PCl₃ + Cl₂
Initial(atm) 0.5 0 0
At equilibrium 0.5 - p p p
- Total pressure at equilibrium = 0.78
- 0.5 - p + p + p = 0.78
- p = 0.28
So partial pressure of PCl₅ = 0.5 - 0.28 = 0.22 atm
Similarly PCl₃ = 0.28 atm & Cl₂ = 0.28 atm
According to law of mass action
- Kp =
- Kp =
- Kp = 0.35
We know Kp = Kc x (RT)Δng
Δng = change in gaseous moles
= product moles - reactant moles
= 2 - 1
= 1
R = universal gas constant = 0.0821 lit. atm. mol⁻¹. K⁻¹
So Kc =
= 0.0081
When you cook the egg, you are changing the egg from a gooey liquid to a soft solid. So, liquid to solid is chemical change, so yeah? ...
<span>Answer:
W must be 5-chloro-2-methylpentane. It can give only 4-methy-1-pentene (Y) upon dehydrohalogenation:
X must be 4-chloro-2-methylpentane. Dehydrohalogenation yields both Y and 4-methyl-2-pentene. (Z)</span>
