Calculate the molar concentration of the Cl⁻ ions in 0.87 M MgCl2(aq).

1 answer:

8 0

The compound MgCl2(aq) is ionic which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MgCl2 that dissolves.
MgCl2(s) --> Mg+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.87 mol MgCl2/1L × 2 mol Cl⁻ / 1 mol MgCl2 = 1.7 M
The answer to this question is [Cl⁻] = 1.7 M

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.

Calculate the average obtained from the following weighings of the same object. Do not forget to include formulas, units, and th

bazaltina [42]

Answer:

10.4376 g

Explanation:

First we calculate the sum of the weighings:

10.4375 g + 10.4381 g + 10.4373 g + 10.4376 g = 41.7505 g

Then we divide the sum by the number of weighings to calculate the average:

Number of weighings = 4

Average = Sum of weighings / Number of weighings

41.7505 g / 4 = 10.4376 g
