Answer:
Abundance for chlorine:
76.9% is 35 Cl and 23.1% is 37 Cl.
Explanation:
the average mass of one mole of chlorine is 35.453g.
Let x be the fraction of the chlorine that is number 35.
1 – x is the fraction that is number 37.
Since they have equal mass number, we equate the two expressions :
34.9689 * x + 36.9659 * (1 – x) = 34.9689 * x + 36.9659 – 36.9659 * x
34.9689 * x + 36.9659 – 36.9659 * x = 35.453
1.997 * x = 1.5359
x = 1.5359 ÷ 1.997
The decimal fraction is approximately 0.769. This means 76.9% is 35 Cl and 23.1% is 37 Cl.
The acceleration due to gravity, denoted by the symbol g, is the acceleration of a body caused by the force acting on the body due to the earth's gravitational field. This force can be written as mg, where m is the mass of the body.
Energy is the correct answer. I hope I helped you
Answer:
The pressure of CH3OH and HCl will decrease.
The final partial pressure of HCl is 0.350038 atm
Explanation:
Step 1: Data given
Kp = 4.7 x 10^3 at 400K
Pressure of CH3OH = 0.250 atm
Pressure of HCl = 0.600 atm
Volume = 10.00 L
Step 2: The balanced equation
CH3OH(g) + HCl(g) <=> CH3Cl(g) + H2O(g)
Step 3: The initial pressure
p(CH3OH) = 0.250atm
p(HCl) = 0.600 atm
p(CH3Cl)= 0 atm
p(H2O) = 0 atm
Step 3: Calculate the pressure at the equilibrium
p(CH3OH) = 0.250 - X atm
p(HCl) = 0.600 - X atm
p(CH3Cl)= X atm
p(H2O) = X atm
Step 4: Calculate Kp
Kp = (pHO * pCH3Cl) / (pCH3* pHCl)
4.7 * 10³ = X² /(0.250-X)(0.600-X)
X = 0.249962
p(CH3OH) = 0.250 - 0.249962 = 0.000038 atm
p(HCl) = 0.600 - 0.249962 = 0.350038 atm
p(CH3Cl)= 0.249962 atm
p(H2O) = 0.249962 atm
Kp = (0.249962 * 0.249962) / (0.000038 * 0.350038)
Kp = 4.7 *10³
The pressure of CH3OH and HCl will decrease.
The final partial pressure of HCl is 0.350038 atm
