Weak Bonds
These bases contain Nitrogen and these create a twofold strand of DNA through not so strong hydrogen bonds. The nitrogen bases, notwithstanding, have particular shapes and hydrogen bond properties so guanine and cytosine just bond with each other, while adenine and thymine additionally bond only. This matching off of the nitrogen bases is called complementarity. All together for hydrogen clinging to happen by any means, a hydrogen bond benefactor must have a corresponding hydrogen bond acceptor in the base opposite it.

Explanation:
Sodium fluoride - 5-chloro-2-(2,4-dichlorophenoxy)phenol (1:1:1) | C12H7Cl3FNaO2 |
Answer:
a list of characteristics that can be used to identify a substance include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.
Explanation:
Step one look for the longest chain of carbon atoms
Longest chain is 7 C atoms
Step 2 look for double bonds or others functional groups
it is present in 3rd carbon
Therefore IUPAC name is 3-heptene
From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.

Answer:
e. the strong base reacts with HA to give A, which is a weak base
Explanation:
Let's consider a buffer made up of a weak acid, HA, and the sodium salt of its conjugate base, NaA. The function is a buffer system is to muffle the change in the pH when an acid or a base is added.
Let's suppose a strong base is added. Then, OH⁻ would be more available. OH⁻ ions react with the acid component of the buffer and its effect is reduced. The corresponding reaction is:
OH⁻ + HA ⇄ A⁻ + H₂O
As we can see, the strong base reacts with HA to give A, which is a weak base.
