Why must the line of origin be drawn in pencil instead of pen on the chromatography strip?
Kruka [31]

Answer:

Because if you use pen, your chromatography will separate also the colors of the pen and not just your sample.

Explanation:

The pencil since is carbon as simple element, is solid and is not dissolved in solvents like commonly are used in paper chromatography, it will not interrupt the separation of the compounds in your mixture, otherwise, your results will be confuse because you are not sure if the spots that you observe is due to the ink pen or due to the mixture that you want to separate.

vagabundo [1.1K]
<h3><u>Answer;</u></h3>

Nitrogen (N)

<h3><u>Explanation;</u></h3>
  • Atoms may lose or gain electrons to achieve stability. Metal atoms lose electrons to attain stable configuration, and as a result they form positively charged ions called cations.
  • <u>Non-metals on the other hand gain electrons to attain stable configuration, and as a result form negatively charged ions called anions.</u>
  • <u>Among the elements given above nitrogen (N) gains electrons to form a negatively charged ion called anion. </u>

What is the difference between an organic compound and an inorganic compound?
Aleks [24]

Answer:

Explanation:

Un compuesto orgánico es todo aquel que tiene como base el carbono. Sus enlaces son covalentes, de carbono con carbono, o entre carbono e hidrógeno. Es sintetizado principalmente por seres vivos, sin embargo, también puede sintetizarse artificialmente. Los compuestos de este tipo constituyen la rama de la química orgánica.

Un compuesto inorgánico es todo aquel que no tiene como principal elemento el carbono y en el que no ocurre un enlace covalente entre el carbono y el hidrógeno. El tipo de enlace más común en este compuesto es el iónico. Los compuestos de este tipo constituyen la rama de la química inorgánica.

Definición

oganicor

Todo aquel compuesto que tiene como elemento principal el carbono y presenta enlaces covalentes de carbono e hidrógeno.

 

Compuesto inorgánico
