Answer:
<h2>D. Nonpolar molecules</h2>
Explanation:
The non-polar molecules are held in place by very weak van der Waals forces, hence making it to have the least melting and boiling point.
The melting points of substances is the point at which it changes from solid to liquid, it can be very difficult to ascertain that why mostly the melting point is given as a range of values.
Answer:
The water lost is 36% of the total mass of the hydrate
Explanation:
<u>Step 1:</u> Data given
Molar mass of CuSO4*5H2O = 250 g/mol
Molar mass of CuSO4 = 160 g/mol
<u>Step 2:</u> Calculate mass of water lost
Mass of water lost = 250 - 160 = 90 grams
<u>Step 3:</u> Calculate % water
% water = (mass water / total mass of hydrate)*100 %
% water = (90 grams / 250 grams )*100% = 36 %
We can control this by the following equation
The hydrate has 5 moles of H2O
5*18. = 90 grams
(90/250)*100% = 36%
(160/250)*100% = 64 %
The water lost is 36% of the total mass of the hydrate
