On occasion, it has been found that the oxidation of borneol doesn't go to completion (possibly because of poor stirring or insu

Answer:

Check the explanation

Explanation:

Here, Nitrogen (N) undergoes oxidation and Chlorine (Cl) undergoes reduction.

To answer your question:

N is oxidized from an oxidation number of -3 to an oxidation number of -1.

Cl is reduced from oxidation number of +1 to an oxidation number of -1.

Now,

Borneol should have a lower Rf because of boiling point.

solution is 2.41 molal toluene (C 7H 8, 92 g/mol) in benzene (C 6H 6, 78 g/mol); i.e. consider toluene the solute, benzene the s
inn [45]

Answer : The molarity of solution is, 1.73 mole/L

Explanation :

The relation between the molarity, molality and the density of the solution is,

where,

d=M[\frac{1}{m}+\frac{M_b}{1000}]

d = density of solution  = 0.876g/cm^3=0.876g/mL

m = molality of solution  = 2.41 mol/kg

M = molarity of solution  = ?

M_b = molar mass of solute (toluene) = 92 g/mole

Now put all the given values in the above formula, we get  the molality of the solution.

0.876g/ml=M\times [\frac{1}{2.41mol/kg}+\frac{92g/mole}{1000}]

M=1.73mol/L

Therefore, the molarity of solution is, 1.73 mole/L

How many grams of potassium iodine, kl,must be added to 500.0 grams of water to produce a 6.00% solution ?
GuDViN [60]

Answer:

grams KI needed = 31.9 grams

Explanation:

? g KI + 500 g water => 6.0% KI solution

let x = grams KI needed.

Percent = part/total x 100% = (x/x+500)·100% = 6.0%

Solve for 'x' ...

x / x + 500 = 6/100 = 0.06 => x = 0.06(x + 500) => x = 0.06x + 30

x - 0.06x = 30 => 0.94x = 30 => x = 30/0.94 = 31.9 gms KI needed.
