I believe that the correct answer here is:
“in neither photosynthesis nor
respiration”
This is because during photosynthesis,
carbon dioxide is converted to glucose.
<span>While during respiration, carbon
dioxide is not split because it is one of the products of respiration hence it
is rather created.</span>
With N2O4's molar mass of 92 grams/mole, there is 1 mole of N2O4 being used.
For every one mole of N2O4 used, two moles of N2H4 are used.
2 moles of N2H4 times the molar mass of N2H4 (32g/mol)
2 moles * (32 grams/mole) = 64 grams
0.9mole of Fe
Explanation:
Given parameters:
Mass of Fe = 50g
Unknown:
Number of moles of iron = ?
Solution:
The number of moles is the particle that contains the avogadro's number of particles.
It is a unit for reporting chemical measurement.
To find the number of moles of a substance;
Number of moles =
Molar mass of Fe= 56g/mol
Number of moles = = 0.9mole of Fe

Answer:
The ratio of the amounts of U 238 and Pb 206 in a rock sample enables the age of the rock to be estimated using the technique of radiometric dating. It moves back in the periodic table until the isotope falls in the band of stability at Pb 206.
