Answer:
The molarity (M) of a solution is the number of moles of solute dissolved in one liter of solution. To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters.
Answer:
Plants add water to the atmosphere
Explanation:
Answer: The answer is K3PO4(s) → 3K+(aq) + PO43–(aq) since water-soluble ionic tripotassium phosphate dissociates completely into K+ and PO43– ions when dissolved, that is, no K3PO4 remains in the solution. Carbonic acid H2CO3 and acetic acid CH3COOH are weak electrolytes since they are weak acids that do not completely ionize, while nonelectrolyte CH3OH do not dissociate into ions.
Answer:
C: the repulsion of electrons and electrons.
Explanation:
According to the VSEPR theory, molecular shapes adjust so that the electrons can be as far apart as possible due to electrons repelling each other, which would mean the only possible answer is C.
Answer:
approximately 106 grams
Explanation:
The molecular mass of Aluminum Oxide is approximately 102 grams per mole.
2×Al=
2×27=54
3×O=3×16=48
54+48=102
200
102
=1.96 moles
There are two atoms of Aluminum in one mole and each atom has a mass of approximately 27 grams so
Mass of Al = 1.96×2×27=106 grams
