Assume the solubility of benzoic acid in ice-cold water is 1.70 g/L and the solubility of benzoic acid in hot water is 68.0 g/L.

lana [24]

Answer:

The volume of water needed to recrystallize 0.700 g of benzoic acid is 10.29 mL.

Explanation:

For the complete recrystalization,

the amount of hot water should be such that, the benzoic acid is completely soluble in it.

As we are given that the solubility of benzoic acid in hot water is 68.0 g/L. Now we have to determine the volume of water is needed to recrystallize 0.700 g of benzoic acid.

we conclude that,

As, 68.0 grams of benzoic acid soluble in 1 L of water.

So, 0.700 grams of benzoic acid soluble in of water.

The volume of water needed = 0.01029 L = 10.29 mL

conversion used : (1 L = 1000 mL)

Therefore, the volume of water needed to recrystallize 0.700 g of benzoic acid is 10.29 mL.

Which type of carbon fixation stores carbon dioxide in acid form?. a. C3. b. C4. c. CAM. d. all of the above

Tcecarenko [31]

Answer is: c) CAM.

CAM (crassulacean acid metabolism) is a carbon fixation pathway.

In plants with CAM carbon fixation, carbon dioxide is stored as the malic acid malate in vacuoles at night.

During the daytime, the malic acid is transported to chloroplasts where it is converted back to carbon dioxide, which is then used during photosynthesis.

Malic acid is an organic dicarboxylic acid with the molecular formula C₄H₆O₅.
