The answer would be B) Absolute time.
1 mm ---------- 0.1 cm
38.2 mm ------ ?
38.2 x 0.1 / 1
= 3.82 cm
Answer:
The number of moles of the chemical constituents will be less than the actual amount.
Explanation:
In calculating empirical formula, we begin with the number of grams of each element, given in the problem.
Given that the spill will affect the mass concentration of the copper chloride solution, calculations to determine the molecular formula (using Molarity = mass conc ÷ molecular mass ) would give a lesser result, which would in turn lower the number of moles of the copper and chloride in the empirical formula calculation.
Answer:
Option (B) pH > 2.34 and pH < 9.60.
Explanation:
In a zwitterionic structure, overall negative charge should be 0.
It means, for glycine, the two functional groups e.g. 
and -COOH should bear equal and opposite charges in it's zwitterionic structure.
of -COOH (in glycine) = 2.34
Therefore, at a pH > 2.34, -COOH group of glycine exists predominantly as 
.
of (in glycine) = 9.60
Therefore, at a pH < 9.60, group of glycine exists predominantly as 
.
Hence we can say that at 2.34 < pH < 9.60, glycine exists predominantly in zwitterionic form due to presence of and in equal amount.
