The bond that join the 3'-hydroxyl group of the deoxypentose of one nucleotide to the 5'-hydroxyl group of the deoxypentose of a
lara [203]

Answer:

phosphodiester bond

Explanation:

<em>Phosphodiester linkage/bond is found in deoxyribonucleic and ribonucleic acids. It is formed from a reaction involving the elimination of water from a reaction involving the hydroxyl groups of two different 5-carbon (pentose) sugars and a phosphate group.</em>

The elimination of water, also known as condensation reaction occur twice, resulting in the formation of two ester bonds which then bind the phosphate group to the pentose sugars to become a phosphodiester bond.

The bond links the 3'-hydroxyl group of one of the pentose sugars and the 5'-hydroxyl group of the other pentose sugar in the nucleotides that make up nucleic acids.

Be sure to answer all parts. For an aqueous solution of sodium chloride (NaCl), determine the molarity of 4.05 L of a solution t
SpyIntel [72]

Answer:

0.824\ \text{M}

5.62\ \text{L}

20.89\ \text{mol}

Explanation:

Molar mass of NaCl = 58.44 g/mol

Mass of NaCl = 195 g

Volume of solution = 4.05 L

Molarity of solution is

\dfrac{195}{4.05}\times \dfrac{1}{58.44}=0.824\ \text{M}

The molarity of the solution is 0.824\ \text{M}

Moles of NaCl = 4.63 mol

Volume is given by

\dfrac{4.63}{0.824}=5.62\ \text{L}

The volume of the solution that contains the required amount NaCl is 5.62\ \text{L}

Volume of solution = 25.35\ \text{L}

Moles of solution is given by

0.824\times 25.35=20.89\ \text{mol}

The number of moles of NaCl is 20.89\ \text{mol}.
