Answer:
Dimer of two peptide chains with 1 mole of molybdenum metal each.
Explanation:
Percentage of molybdenum in protein = 0.08%
Molecular mass of nitrate reductase = 240,000 g
Mass of molybdenum = x
Moles of molybdenum =
Each peptide chain of nitrate reductase contain 1 mole of molybdenum.
This means that nitrate reductase is composed of to two peptide chains. And in each peptide there is a single mole of molybdenum metal.
Explanation:
<h3>Phosphorus moves in a circle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals.</h3>
Dilute, aqueous potassium nitrate solution is best classified as a:
(2) homogeneous mixture
Explanation:
A homogeneous mixture may be a solid, liquid, or volatilized mixture that has a similar proportions of its parts throughout any given sample.
Conversely, a heterogeneous mixture has parts whose proportions vary throughout the sample.
Because it's a combination of water and nitrate and you cannot clearly see the separation within the mixture .
