Answer:
1.274 moles
Explanation:
The equation for the reaction can be represented as follows:
⇄ 
+ 
K = 0.060
K = ![\frac{[PCl_3][Cl_2]}{[PCl_5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BPCl_3%5D%5BCl_2%5D%7D%7B%5BPCl_5%5D%7D)
Concentration of = 
Concentration of = 
Concentration of = 0.398 moles
If we construct an ICE table for the above equation; we have:
⇄ +
Initial 0.398 0 0
Change - x + x + x
Equilibrium (0.398 - x) x x
K =
K = ![\frac{[x][x]}{[0.398-x]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bx%5D%5Bx%5D%7D%7B%5B0.398-x%5D%7D)
K = 
0.060 =
0.06(0.398-x) = x²
0.02388 - 0.060x = x²
x² + 0.060x - 0.02388 = 0 (quadratic equation)
a = 1; b= 0.06; c= -0.02388
Using quadratic formula;
= 
= 
= 
= 
= 
= 
or 
= 
or 
= 0.1274 or -0.1874
We go by the positive value which says:
[x] = 0.1274 M
number of moles = 0.1274 × 10.0
= 1.274 moles
∴ the number of moles of Cl₂ produced at equilibrium = 1.274 moles
You can wait until he either breaks up (if he does) or if just forget about him and go for another guy.
Use the PV = nRT equation T is in Kelvins = 31 + 273 = 304 K
P(0.5) = (2.91)(0.0821)(304)
P(0.5) = 72.6289
P = 145.25 atm or 1.45x10^2 atm

ln (p1/p2) =( dH / R) (1/T2 - 1/T1)
ln (760 Torr /520Torr) =( 40,700 Joules / 8.314 J molâ’1K-1)(1/T2 - 1/373K)
ln (1.4615) =( 4895.35)(1/T2 - 0.002681)
0.37946 = 4895.35/T2 - (0.002681)(4895.35)
0.37946 = 4895.35/T2 - (13.124)
0.37946 + 13.124 = 4895.35/T2
13.5039 = 4895.35/T2
T2 = 4895.35 / 13.5039
T2 = 362.51
answer is 362.51 Kelvin

Answer:
<h2>The sequence is; b, e, a, d, c
</h2>
Explanation:
1. In a decomposition reaction; One reactant is broken down into two or more than two products is called decomposition.
2. A combustion reaction; A fuel is combined with oxygen to produce carbon dioxide and water, this reaction is called combustion reaction.
3. A synthesis reaction; it occurs when two or more reactants combine to form one product is known as synthesis reaction.
4. Double Replacement Reaction; Two compounds react to form two different compounds is known as double Replacement Reaction.
5. A single replacement reaction; occurs when a compound reacts with an element to form a new compound , this reaction is called as single replacement reaction.
