Answer : The correct option is, (A) NO_2

Explanation :

Ionic bond : It is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.

The ionic compound is formed between a metal and a non-metal.

Covalent bond : It is defined as the bond that is formed when sharing of electrons takes place between the atoms.

The covalent compound is formed between two non-metals.

(a) NO_2

It is a covalent compound in which nitrogen and oxygen are non-metals. The NO_2  is formed when one nitrogen atom share their electrons with two oxygen atoms.

(b) LiCl

It is an ionic compound in which lithium is a metal and chlorine is a non-metal. The LiCl  is formed by the complete transfer of electrons.

(c) AlCl_3

It is an ionic compound in which aluminum is a metal and chlorine is a non-metal. The AlCl_3  is formed by the complete transfer of electrons.

(d) Na_2S

It is an ionic compound in which sodium is a metal and sulfur is a non-metal. The Na_2S  is formed by the complete transfer of electrons.

Hence, the covalent compound is NO_2

Katena32 [7]

The AP Biology teacher is measuring out 638.0 g of dextrose (C6H12O6) for a lab the moles of dextrose is this equivalent to is 3.6888 moles.

<h3>What are moles?</h3>

A mole is described as 6.02214076 × 1023 of a few chemical unit, be it atoms, molecules, ions, or others. The mole is a handy unit to apply due to the tremendous variety of atoms, molecules, or others in any substance.

To calculate molar equivalents for every reagent, divide the moles of that reagent through the moles of the restricting reagent. The calculation is follows:

  • 655/12 x 6 + 12+ 16 x 6
  • = 655/ 180 = 3.6888 moles.

The base that will NOT combine with 2-deoxyribose to form a nucleic acid is _____.
beks73 [17]

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.
