Answer:
Milk
Explanation:
Typically, the lower a substance is on the pH scale, the higher its acidity is and the higher the H+ concentration is. Conversely, the higher a substance is on the pH scale, the more basic it is and the lower the H+ concentration is. To be considered an acid, a substance has to be below 7 on the pH scale, since 7 is neutral. The highest substance on the pH scale that is still below 7 is milk, with a pH of about 6.5. Therefore, this is the answer. Hope this helps!
Answer:
Polar and Non-Polar Molecules
Explanation:
Answer:
[HI] = 0.7126 M
Explanation:
Step 1: Data given
Kc = 54.3
Temperature = 703 K
Initial concentration of H2 and I2 = 0.453 M
Step 2: the balanced equation
H2 + I2 ⇆ 2HI
Step 3: The initial concentration
[H2] = 0.453 M
[I2] = 0.453 M
[HI] = 0 M
Step 4: The concentration at equilibrium
[H2] = 0.453 - X
[I2] = 0.453 - X
[HI] = 2X
Step 5: Calculate Kc
Kc = [Hi]² / [H2][I2]
54.3 = 4x² / (0.453 - X(0.453-X)
X = 0.3563
[H2] = 0.453 - 0.3563 = 0.0967 M
[I2] = 0.453 - 0.3563 = 0.0967 M
[HI] = 2X = 2*0.3563 = 0.7126 M
I believe that the answer is Oxygen. Hope this helps. :)
A believe it’s called a “group”
Correct me if I’m wrong!
