The splitting of carbon dioxide to form oxygen gas and carbon compounds occurs during

Oxana [17]

Answer:

neither photosynthesis nor respiration.

Explanation:

Photosynthesis is the process by which the green plants, in the presence of sunlight makes their own food. In the process carbon dioxide is absorbed and oxygen is released.

$6CO_2 + 6H_2O\ (sunlight)\ \rightarrow C_6H_{12}O_6 + 6O_2$

Respiration is the intake of oxygen and the metabolism of the glucose in which it is breakdown and releases carbon dioxide.

$C_6 H_{12}O_6 + 6O_2\rightarrow 6CO_2 + 6H_2O + ATP$

In neither of the two processes, carbon dioxide is splitted.

What are the units of k in the following expression: rate = k [A][B]?s-1M-1s-1M-2s-1M

SVETLANKA909090 [29]

Rate of the reaction is represented as

Rate=k[A][B]

Rate represents change in product concentration with time that has a unit Ms- Whereas concentration of each reactant can be represented as M . so the expression will become:

Ms-1=k[M][M]

k=M-1 s-1.
