Phosgene is formed from carbon monoxide and chlorine. At 611 oC, Kc is approximately 16.5 M-1 or L/mol. Calculate Kp (in atm-1)
defon

Answer:

Kp is 0.228/atm

Explanation:

This is the reaction:

CO + Cl<u>₂</u> → CCl₂O

1 mol of carbon monoxide and 1 mol of chlorine produce 1 mol of phosgene.

Formula for Kp which derivates from Kc is:

Kp = Kc (R.T)ⁿᵇ ⁻ ⁿᵃ

Δп = nb (moles in the products) - nₐ(moles in the reactants)

Δп = 1 - 2 = -1

T is T° in K → T°C + 273 = 611°C +273 = 884K

R → Universal constant gas → 0.082 L.atm/mol.K

We replace the data: Kp = 16.5 L/mol (0.082 . 884K)⁻¹ → 0.228/atm

When a pot of water has been boiling vigorously for several minutes, the bubbles that emerge from the liquid water are composed
kumpel [21]
Well, water is composed H2 gas and O2 gas in a 2:1 ratio, and the bubbles that form at the bottom of the pan is just the water changing from a liquid to a gas, and im pretty sure its water vapor that comes out of the pan. I hope that helped??? :)

Answers only please 100pts and brainliest. you will be reported for wrong answers.
Ierofanga [76]

Answer:

K= 25.16%

Mn= 34.59%

O= 40.25%

Explanation:

KMnO_4

Find the total mass of the compound. You can do this by multiplying by the molar mass.

K=40*1=40\\Mn=55*1=55\\O=16*4=64

add them:

40+55+64=159g

Now convert each element individually to grams using molar mass

1molK(\frac{40gK}{1molK} )=40gK

1molMn(\frac{55gMn}{1molMn} )=55gMn

4molO(\frac{16gO}{1molO})=64gO

Divide by the mass of the compound and multiply by 100

K=\frac{40g}{159g} *100=25.16

Mn=\frac{55g}{159g}*100=34.59

O=\frac{64g}{159g}*100=40.25
