Answer:

Uracil

Explanation:

The base that will NOT combine with 2-deoxyribose to form a nucleic acid is Uracil.

2-deoxyribose is a pentose sugar found in the DNA (Deoxyribonucleic acid). It is devoid of oxygen in its 2' position. The bases found in DNA are Adenine, Guanine, Cytosine and Thymine. Adenine, Guanine, and Cytosine are also found in RNA (Ribonucleic acid). Thymine is not present in RNA, it is only found in DNA. The base found in RNA is Uracil which in turn is not present in DNA. The five carbon sugar present in RNA is ribose which combines with Uracil.

What is the empirical formula of a compound that breaks down into 4.12g of N and 0.88g of H? N 5 H NH 3 NH 4 N 4 H
Marysya12 [62]

<u>The </u><u>emperical formula </u><u>can be </u><u>calculated </u><u>as follows:</u>


<u>mass :</u>   4.12g of N            and        0.88g of H

<u>moles:</u>   4.12g/14.007       and        0.88g/1.008

               

<u>moles:</u>   0.294                   and        0.873


<u>moles/smallest number</u>:   (gives the ratio of atoms)


             0.294/0.294                and           0.873/0.294

                   1                               and             2.969

                    1                              and              3



The simplest ratio of N : H is 1 : 3

<u>Hence the </u><u>emperical formula </u><u>is </u><u>NH3</u>


<u>Explanation:</u>

 1.   The emperical formula can be found by getting  the <u>simplest ratio of atoms in a molecule.</u>

2. To get the simplest ratio of atoms we find out the <u>number of moles of each atoms in it.</u>

3. From the number of moles of atoms we can find the simplest ratio of each atom by dividing the <u>number of moles by the smallest number.</u>
