Answer:
D. A and B
Explanation
as frequency is inversely proportional to wavelength. formula for calculating wavelength is
wavelength = wave velocity/frequency.
as wavelength is inversely proportional so increase in wavelength will cause decrease in frequency and vice versa . so A and B are the right answer.
Answer:
1.68 M
Explanation:
Molar mass (KNO3)= 101.1 g/mol
89g KNO3* 1mol/101.1 g = 89/101.1 mol
(89/101.1 mol)/0.525 L= 1.68 mol/L = 1.68 M
Answer:
Solvation is affected by inter molecular forces in a sense that these attractive forces overcome the forces that holds the solute and solvent particles together making the solute particles separate form the solvent particles.
