A specific combination of bonded atoms which always react in the same way, regardless of the particular carbon skeleton is known as the functional group. These are specific groups of atoms or bonds within organic molecules that accounts for the characteristic chemical reactions of those molecules. Examples of functional groups are the Carbonyl group, alkyl Halides, aldehydes and ketones among others.
2.0 L in mL :
2.0 x 1000 => 2000 mL
1.26 kg in g :
1.26 x 1000 => 1260 g
D = mass / volume
D = 1260 / 2000
D = 0.63 g/mL

Taken together, these results suggest that eugenol may serve as local anesthetics for other pathological pain conditions in addition to its wide use in dental clinic.
Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass.
Answer:
A
Explanation:
According to Coulomb's Law, like charges<u><em> repel </em></u>each other, whereas unlike charges<em><u> attract</u></em> each other. This applies to all charged particles.
When NaCl dissociates into its ions in water, we observe the following ions in the system:
<em>Na+ (positive)</em>
<em>Cl - (negative)</em>
<em>H+ (positive)</em>
<em>OH- (negative)</em>
The only correct option is A where the negatively charged oxygen atoms are attracted to the positively charged sodium atoms.
In option B the charge of the oxygen atom is incorrectly mentioned as positive. In option C, the charge of hydrogen atoms is incorrectly mentioned as negative, and in option D the charges of the atoms are correct, but the pairing is incorrect as like charges repel each other.
