General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
30 g O
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of O - 16.00 g/mol
<u>Step 3: Convert</u>
<u />
= 1.12913 × 10²⁴ atoms O
<u>Step 4: Check</u>
<em>We are given 1 sig fig. Follow sig fig rules and round.</em>
1.12913 × 10²⁴ atoms O ≈ 1 × 10²⁴ atoms O
Answer: because of isotopes
relative atomic mass =(75/100 × 35) + (25/100 × 37) = 35.5
isotopes of any element behave the same chemically because neutrons do not have any charge

Answer:
The phosphodiester connects the 3′ carbon of one nucleotide to the 5′ carbon of another nucleotide
Explanation:
The phosphodiester bond is a covalent bond where a phosphate group is attached to adjacent C through an ester bond, which is a consequence of a condensation reaction between the two sugar hydroxyl groups and the phosphate group.
The diester bond between phosphoric acid and two sugar molecules in the DNA and RNA skeleton binds two nucleotides forming polymers known as oligonucleotides.
The phosphodiester bond binds a C3` with a C5` in both DNA and RNA
(base)1-(sugar)-OH + HO-P(O)2-O-(sugar)-(base)2
------>
------> (base)1-(sugar)-O-P(O)2-O-(sugar)-(base)2
During the reaction of two of the hydroxyl groups in phosphoric acid with a hydroxyl group in two other molecules two ester bonds in a phosphodiester group are formed. A condensation reaction in which a water molecule is lost generates each ester bond.
