Answer:
(a) Polarity of phase: 1. Stationary phase is polar
b) Eluent strength of solvent: 1. Increases as solvent becomes more polar
c) Nature of solutes.1. Polar
d) Nature of solute interaction:2. More soluble in mobile phase as the polarity of the mobile phase decreases

h) Nature of solute interaction: 2. More soluble in mobile phase as the polarity of the mobile
Explanation:
I'll be using dimensional analysis to help out.
2.5mol Na2O * ( X gNa2O / 1 molNa2O) = ? gNa2O
X gNa2O is the molar mass of the molecule. To find that we must add up the molar masses of all of the elements in the molecule.
There are 2 Na (Sodium).
And 1 O (Oxygen).
The Molar Mass of Na = 2 * 22.99 g/mol (It's multiplied by 2 because there are 2 of them in the molecule)
The Molar mass of O = 16.00 g/mol
If you are confused on where I found them. Let me enlighten you! I found them from a periodic table of elements.
Add those two values together to get a total molecular molar mass of:
38.99g/mol
2.5mol Na2O * ( 38.99 gNa2O / 1 molNa2O) = 97 gNa2O
Answer:
I think its evaporate
Explanation:
because when the heat absorbed the chemicals evaporate
