<h3><u>Question:</u><u>-</u></h3>
Criteria for purity of organic solid is
(a) boiling point
(b) melting point
(c) specific gravity
(d) none of these
<h3><u>Answer</u><u>:</u><u>-</u></h3>
(b) melting point
<h3><u>Explanation</u><u>:</u><u>-</u></h3>
Melting point is considered to be the best measure of purity of a substance.
When a purified sample is mixed with a small amount of pure compound , melting point of the mixture is determined.
If a substance is impure (contains impurities/other substance) the melting point of that substance will change.
________________________________
The purity percentage of a substance can be calculated by dividing the mass of the pure chemical by the total mass of the sample and multiplying this number by 100.
[Mass of pure chemical/total mass × 100]
probably radiation. the sun's radiation waves are heating up the windows that are also heating up the house. but idek anymore sorry sister
Explanation:
Carbohydrates covalently linked to proteins (glycoproteins) or lipids (glycolipids) are also a part of cell membranes, and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a fluid lipid bilayer with floating proteins and carbohydrates.
