Answer:
Incomplete combustion of fuels produces a very poisonous gas called carbon monoxide:Excessive inhaling of carbon dioxide gas can kill a person.
I don't know if this is correct, your question did not have much context.
I believe the answer is a because 2 times 12 is 24. Hope this helped
Answer:
Answer: (1R,2S) / (1S, 2R) , (1R,2R) / (1S, 2S)
Explanation:
Sodium borohydride reduction of benzoin will give four possible stereo isomers out of which are (1R,2S) - (1S, 2R) isomers and (1R,2R) - (1S, 2S) isomers which are known as enantiomers.
In general enantiomers show single spot in the TLC as they do not show any difference in Rf value (i.e) (1R,2S) - (1S, 2R) isomers show only one spot although they are two compounds and also (1R,2R) - (1S, 2S) isomers also show one spot. That is the reason why you are observing two spots in the TLC ( of reaction mixture) other than starting materilal.
Answer:
The particles that compose a gas are so small compared to the distances between them that the volume of the individual particles can be assumed to be negligible.
Explanation:
This is a postulate of the Kinetic Molecular Theory.
A is wrong. KMT assumes the that the volume of the particles is negligible.
B is wrong. KMT assumes that the distance between the particles is muck greater than their size.
D is wrong. It takes the large distances as a fact. KMT uses this as an assumption.
