If the hydronium concentration decreases, the pH increases, resulting in a solution that is less acidic and more basic
Answer: The number of protons plus the number of neutrons equals the atomic mass.
Explanation:
Atomic mass is defined as total number of protons and neutrons in the atom.
It is an average mass of an atom.
It is expressed in atomic mass unit that is a.m.u.
It is denoted with symbol 'A'.
.
Answer:
+5
Explanation:
You use the rules for oxidation numbers to calculate that the oxidation number of N is +5.
Answer:
you would need to multiply 50 times 2 wich is 100 so i beleive its 100
Explanation:
Depression in freezing point is a colligative property i.e. it depends upon under of solute particles present in solution.
Depression in freezing point (ΔTf) is mathematically expressed as,
ΔTf = Kf X m ............... (1)
where Kf = cryoscopic constant
m = molality of solution
If solvent used is water, Kf = 1.853 K Kg/mol and Freezing point of pure solvent = 0 oC
∴ΔTf = 0.58 K ............... (2)
Substituting 2 in 1 we get
0.58 = 1.853 X m
∴ m = 0.313 m
Thus, molality of solution is 0.313 m
