Explanation:
From the given parameters we can calculate the mass and number of moles in this amount of solution of NaCl
Volume of solution = 1L
Molarity = 0.5M
We know that this is a solution. The molarity indicates that amount of solute was dissolved in a solvent.
To find the number of moles of solution;
Number of moles = molarity x volume
molarity is the the number of moles of solute in a solution.
input the variables;
Number of moles = 0.5 x 1 = 0.5moles
Mass of NaCl:
Mass of NaCl = number of moles x molar mass
molar mass of NaCl = 58.54g/mol
Mass of NaCl = 0.5 x 58.54 = 29.27g

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.

denoting a process involving substances in the same phase (solid, liquid, or gaseous).
Herogeneous:
of or denoting a process involving substances in different phases (solid, liquid, or gaseous).
Answer:warm
Explanation: because it is in the southern hemisphere so in the winter while the northern hemisphere is in a cold winter the southern hemisphere is in a warm winter due to it being in the southern hemisphere where temperatures are really warm in the southern hemisphere.
