Chemists studied the formation of phosgene by sealing 0.96 atm of carbon monoxide and 1.15 atm of chlorine in a reactor at a cer
lukranit [14]

Answer:

3.9

Explanation:

Let's consider the following reaction at equilibrium.

CO(g) + Cl₂(g) ↔ COCl₂(g)

We can find the pressures at equilibrium using an ICE chart.

       CO(g) + Cl₂(g) ↔ COCl₂(g)

I       0.96       1.15            0

C        -x           -x            +x

E    0.96-x    1.15-x           x

The sum of the partial pressures is equal to the total pressure.

pCO + pCl₂ + pCOCl₂ = 1.47

(0.96-x) + (1.15-x) + x = 1.47

2.11 - x = 1.47

x = 0.64

The pressures at equilibrium are:

pCO = 0.96 - x = 0.32 atm

pCl₂ = 1.15 - x = 0.51 atm

pCOCl₂ = x = 0.64 atm

The pressure equilibrium constant (Kp) is:

Kp = pCOCl₂ / pCO × pCl₂

Kp = 0.64 / 0.32 × 0.51

Kp = 3.9

Which two factors affect the strength of<br> a metallic bond?
jeyben [28]

Answer: Number of protons and number of valance electrons.

Explanation:

There are three factors which determine metallic bond strength. greater the no of protons, greater will be attraction between nucleus and valance shell electrons and stronger will be metallic bond. greater no of valance electron, greater will be attractions between nucleus and electrons and stronger will be bond.

At a certain temperature and pressure, 1 L of CO2 gas weighs 1.55 g. What is the mass of 1 L of N2 gas at the same temperature a
Karolina [17]

Answer:Set up a proportion os V1/n1 = V2/n2. V is the volume, n is the amount in MOLES, not grams. Convert the CO_2 to moles, then solve and find that the amount of N_2 should be the same amount of moles. Then use the molar mass of N_2 (28.02 grams/mole) to convert that amount of moles into grams. That's your answer.
