Describe the R group found within an amino acid
madreJ [45]

Hello!

An amino acid has five basic parts. An amino group, a carboxyl group, a central carbon atom, a hydrogen, and a R group.

The r group is the side chain specific to each amino acid. The r group varies between each kind of amino acid, while everything else stays the same. Therefore, the r group decides the identity of the amino acid.

Hope this helps! Let me know if you need a more specific explanation.

What is the hypothetical van't Hoff factor of magnesium nitrate, Mg(NO3)2?
vovangra [49]

Answer:

The hypothetical van't Hoff factor of magnesium nitrate,Mg(NO_3)_2 is <u>3 .</u>

Explanation:

Lets calculate -

Mg(NO_3)_2\rightarrow Mg^2^+ +2NO_3^-

We know that ,

i=\alpha n+(1-\alpha )

Dissociation should be 100% for the hypothetical vant hoff factor , that is

\alpha =1 and n=3 for  Mg(NO_3)_2

Therefore , putting the given values ,

i=1\times3+(1-1 )

i=3+0

i=3

<u>Hence , the answer is 3.</u>
