Which class of compounds contains only carbon, hydrogen, and nitrogen?
Likurg_2 [28]
<h2>Answer: </h2>

Nitrogen forms many thousands of organic compounds. Most of the known varieties may be regarded as derived from ammonia, hydrogen cyanide, cyanogen, and nitrous or nitric acid. The amines, amino acids, and amides, for example, are derived from or closely related to ammonia.

<h3>Explanation: </h3>

A carbohydrate has only Carbon, Hydrogen and Oxygen, with the hydrogen and oxygen in the ratio 2:1.

Examples are glucose C6H12O6 and table sugar C12H22O11

A protein is made of amino acids. Amino acids have an amino group which is −NH2.  

So without nitrogen atoms the compound cannot be a protein.

Nucleic acids are organic compounds that contain carbon, hydrogen, nitrogen but they also contains phosphorus and oxygen. They are made of smaller units called nucleotides.

So;

Simple Amines are the class of organic compounds that only contains Carbon, Hydrogen and Nitrogen.

What component of amino acid structure varies among different amino acids?
givi [52]

Answer

The components of the r group of amino acid structure varies among different amino acids

Explanation  

As the functional group for amino acids is as:  

R-CH-COOH  

 I  

NH2  

only R differs so amino acids also differs. If R is “H” then amino acid is glycine and if R is “CH3” then amino acid is alanine. Hence, R is different for different amino acids. Other components as alpha carbon ( C ), carboxyl group ( COOH ) and amino group ( NH2 ) is fixed for every amino acid.

Which term describes the molecule shown below h-c-c-h ethyne c2h2?
Andru [333]
Ethyne also known as Acetylene and is the simplest Alkyne belonging to  Unsaturated Hydrocarbons. It contains triple bond between two carbon atoms in a molecule. Carbon atoms in Acetylene are sp Hybridized and has a linear shape with bond angle of 180° is present between C-C-H bonds. This compound is also called as Binary Compound because it is made up of two elements i.e. Carbon and Hydrogen. The terminal Hydrogen in Acetylene is slightly Acidic in nature, and this compound can donate terminal proton to any strong base. These compounds generally give Electrophillic Addition Reactions.

Match the separation techniques with the correct descriptions.
nordsb [41]

Answer:

Explanation:

1 = A

Sublimation is the process where by a sample is heated to pass through solid phase to gaseous phase without the intermittent liquid phase. Example of substance that sublime is camphor.

2 = D

Decantantion

5 = F

Filtration is the process a liquid from solid using a porous material. This technique requires a set up and a good porous material eg filter paper.

6 = B

This technique is to separate a mixture of solids by converting them from solid phase to gaseous phase since they sublime.

3 = deposition.

The answer isn't in the option but deposition is the process of substance in gaseous phase to change into solid state without passing through liquid phase. Deposition is the opposite of sublimation.

4 = E
