It’s chlorine (Cl) having the atomic number 17
Answer:
The equilibrium constant Kp for this reaction is 0.0030
Explanation:
Step 1: Data given
Partial pressure at the equilibrium:
pHCl = 76.9 atm
pO2 = 66.3 atm
pCl2 = 40.7 atm
pH2O = 65.1 atm
Step 2: The balanced equation
4 HCl(g) + O2(g) → 2 Cl2(g) + 2 H2O(g)
Step 3: Calculate the equilibrium constant Kp
Kp = ((pH2O²)*(pCl2²)) /(pO2)*(pHCl^4))
Kp = (65.1²*40.7²) / (66.3*(76.9^4))
Kp = 0.0030
The equilibrium constant Kp for this reaction is 0.0030
The number of moles of the gas is 0.0396 moles.
<h3>What is the ideal gas equation?</h3>
The ideal gas equation is used to determine the relationship between the variables; temperature, pressure, volume and the number of moles of a gas. We know that the gas laws are used to understudy the parameters that has to do with gases.
Thus;
Volume = 1000.0 cm 3 or 1 L
Gas constant = 0.082 atmLK-1Mol-1
Temperature = 32 o C + 273 K = 305 K
Pressure = 752 mm Hg or 0.99 atm
Thus;
PV = nRT
n = PV/RT
n = 0.99 atm * 1 L/0.082 atmLK-1Mol-1 * 305 K
n = 0.0396 moles

Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. ... When iron nails are placed in a copper sulfate solution, iron displaces copper to form iron sulfate. Slowly, the blue color of the copper sulfate solution turns into green.
