Why can't we use chromatography paper to separate different colored pencils?

1 answer:

3 0

Chromatography is a way of separating a mixture of chemicals which are in gas or liquid form. when the paper absorbs the liquid, the different colours from the colouring pencils will not be separated because they are insoluble solid pieces,also because they are solid the colours will not be able to creep up the paper which is why chromatography can not be used to separate different coloured pencils.

the atomic mass of chlorine is 35.45 u. Is it possible for any single atom of chlorine to have a mass number of exactly 35.45? E

KonstantinChe [14]

No, this number is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed value.

The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes (different Cl atoms in nature). Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units.

A student is asked to standardize a solution of potassium hydroxide. He weighs out 1.08 g potassium hydrogen phthalate (KHC8H4O4

natka813 [3]

Answer:

A. 0.143 M

B. 0.0523 M

Explanation:

Let's consider the neutralization reaction between potassium hydroxide and potassium hydrogen phthalate (KHP).

KOH + KHC₈H₄O₄ → H₂O + K₂C₈H₄O₄

The molar mass of KHP is 204.22 g/mol. The moles corresponding to 1.08 g are:

1.08 g × (1 mol/204.22 g) = 5.28 × 10⁻³ mol

The molar ratio of KOH to KHC₈H₄O₄ is 1:1. The reacting moles of KOH are 5.28 × 10⁻³ moles.

5.28 × 10⁻³ moles of KOH occupy a volume of 36.8 mL. The molarity of the KOH solution is:

M = 5.28 × 10⁻³ mol / 0.0368 L = 0.143 M

Let's consider the neutralization of potassium hydroxide and perchloric acid.

KOH + HClO₄ → KClO₄ + H₂O

When the molar ratio of acid (A) to base (B) is 1:1, we can use the following expression.

$M_{A} \times V_{A} = M_{B} \times V_{B}\\M_{A} = \frac{M_{B} \times V_{B}}{V_{A}} \\M_{A} = \frac{0.143 M \times 10.1mL}{27.6mL}\\M_{A} =0.0523 M$

What is a general representation of a secondary amine?

Makovka662 [10]

Amines are organic compound obtained from ammonia by replacement of one or more hydrogen atoms by organic groups. If one of the 'H' atom of NH3 is replace by R = alkyl group, they are referred as primary amine. If two 'H' atoms of NH3 are replace by same or different alkyl group, they are referred as secondary amine.
