Answer:
The answer to your question is K = 1.48
Explanation:
Balanced chemical reaction
Br₂ + I₂ ⇒ 2IBr
Process
1.- Calculate the concentration of each of the reactants
[Br₂] = 0.6 mol / 1 L
= 0.6 M
[I₂] = 1.6 mol / 1 L
= 1.6 M
[IBr] = 1.19 M
2.- Write the equation of the Equilibrium constant
K = [IBr]² / [Br₂][I₂]
-Substitution
K = [1.19]² / [0.6][1.6]
- Simplification
K = 1.4161 / 0.96
- Result
K = 1.48
B. The amount of pressure exerted by a solid is solely dependent on its mass
let me know if i am wrong
1.Products of most combustion reactions are:
Carbon dioxide and water
2.Alloys are made by melting and combining metals together.
Chemical changes involve electrons,in this process no electron is used/shared or given.
Thus,its not a chemical change.
For the reaction 2 K + F2 --> 2 KF,
consider K atomic wt. = 39
23.5 g of K = 0.603 moles, hence following the molar ratio of the balanced equation, 0.603 moles of potassium will use 0.3015 moles of F2. (number of moles, n = 0.3015)
Now, following the ideal gas equation, PV = nRT
P = 0.98 atm
V = unknown
n = 0.3015 moles
R = 82.057 cm^3 atm K^-1mole^-1 (unit of R chosen to match the units of other parameters; see the reference below)
T = 298 K
Solving for V,
V = (nRT)/P = (0.3015 mol * 82.057 cm^3 atm K^-1 mol^-1 * 298 K)/(0.98 atm)
<span>
solve it to get 7517.6 cm^3 as the volume of F2 = 7.5176 liters of F2 gas is needed. </span>
