Answer:
28.6
Explanation:
Step 1: Write the balanced reaction at equilibrium
CO(g) + Cl₂(g) ⟺ COCl₂(g)
Step 2: Calculate the equilibrium partial pressure (in atm) of phosgene?
We will use the expression for the pressure equilibrium constant (Kp)
Kp = pCOCl₂ / pCO × pCl₂
pCOCl₂ = Kp × pCO × pCl₂
pCOCl₂ = 1.49 × 10⁸ × 4.38 × 10⁻⁴ × 4.38 × 10⁻⁴ = 28.6
The oxidation state of a substance is the electric charge it is exhibiting in a given state. This may be determined by looking at the oxidation states of accompanying atoms as well as the charge on the complete molecule.
In this case:
Molecular charge: 0
Oxidation state of oxygen: -2 (it is a group 6 element)
Thus,
S + 3 * -2 = 0
S = 6
Sulfur is exhibiting an oxidation state of +6.
Answer:
Which chemical equation represents a redox reaction?
Explanation:
Which chemical equation represents a redox reaction?
Answer:
B and BBr3
Explanation:
1) 3HBr + B = BBr3 + H2 (double all equation because H2)
2) 6HBr + <em>2B </em>= <em>2BBr3</em> + 3H2
