What effect will increased pressure have on 4A (g) + 5B (g) ---> 2C (g) + 7D (g) 
Pie

Answer:

  • <em><u>Option a. no change</u></em>

Explanation:

The question makes sense only if the equation is an equilibrium reaction:

  • <em>4A (g) + 5B (g) ⇄ 2C (g) + 7D (g) </em>

This is, A and B react to produce C and D, forward reaction; and C and D react to form A and B, reverse reaction.

Then, you can study the effect of increased pressure using LeChatelier's principle.

To counteract the disturbing effect produced by increased pressure on the equilibrium, the system will react shifting the toward to the side where the pressure could be decreased.

That would be toward the side that has less gas molecules.

Since both sides have 9 molecules (4 + 5 = 2 + 7 = 9), the equilibrium concetrations will not change.

That is represented by the first choice: no change.

If the human body contains about 50 deciliters of blood, and the blood has about 15 grams of hemoglobin per deciliter, and all o
Tcecarenko [31]

Answer:

The blood will contain 750 grams of O2

Explanation:

Volume of blood in the human body = 15 deciliters

Mass of hemoglobin per deciliter of blood = 15 grams

Mass of hemoglobin in 50 deciliters of blood = 50×15 = 750 grams

Since all the hemoglobin molecules are saturated with O2, mass of O2 in the blood will be the same as mass of hemoglobin molecules in the blood.

Therefore, mass of O2 in the blood is 750 grams
