Answer:
4.22 mol H₂O
Explanation:
Step 1: Write the equation for the synthesis of water
2 H₂ + O₂ ⇒ 2 H₂O
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to H₂O is 1:2.
Step 3: Calculate the moles of water produced from 2.11 moles of oxygen
We will use the previously established molar ratio.
2.11 mol O₂ × 2 mol H₂O/1 mol O₂ = 4.22 mol H₂O
Answer:
H. The ermine's dark brown coat in the summer changes to white is the winter.
Explanation:
If the ermine want to survive and not get attacked by predators, then they need to change the color of the coat from brown to white
Answer:
Part A
Kp = 3.4 x 10⁴
Part B
Kp = 2.4 x 10⁻¹⁴
Part C
Kp = 1.2 x 10⁹
Explanation:
2PH₃(g) + As₂(g) ⇌ 2 AsH₃(g) + P₂(g) Kp = 2.9 x 10⁻⁵
Kp = [AsH₃]²[P₂]/[PH₃]²[As] = 2.9 x 10⁻⁵
Part A
it is the inverse of the equilibrium given
Kp(A) = 1/ Kp = 1 / 2.9 x 10⁻⁵ = 3.4 x 10⁴
Part B
Is the equilibrium where the coefficients have been multiplied by 3,
Kp(B) = ( Kp )³ = ( 2.9 x 10⁻⁵ )³ = 2.4 x 10⁻¹⁴
Part C
This is the reverse equilibrium multipled by 2.
Kp(C) = ( 1/Kp)² = ( 1/ 2.9 x 10⁻⁵ )² = 1.2 x 10⁹
