The number of atoms present in 2.5 mole of triatomic gas is equivalent to ​
RUDIKE [14]

Answer: 1.41725 X 10^{24} atoms

Explanation:

One male of any gas containing no. of atoms$=6.023\times10^{23}$

2.5 moles of gas containing no. of atoms$=2.5\times6.023\times10^{23}$$=15.0575\times10^{23}$

The given gas is triatomic gas. Hence

No. of atoms$=3\times15.075\times10^{23}$

$=14.1725\times10^{23}$\\$=1.41725\times10^{24}$

kati45 [8]

Answer:

The correct answer is a The calvin cycle requires products only produced when the photsystems are illuminated .It is often too cold at night for the reaction to take place.

Explanation:

It is true that the reactions of calvin cycle are not directly depends on light but depends on the products such as ATP and NADPH produced during light reaction.

       ATP and NADPH is formed by the illumination of photosystems by sun light.So during night time there is no chance for the light dependent illumination of the photosystems.

    As a result the ATP and NADPH are not formed during night .That"s why reactions of calvin cycle does not occur at night.
