Answer:
OH⁻
Explanation:
A base is defined as a substance which interacts with water to yield excess hydroxide ions, OH⁻, in an aqeous solution.
Examples are Sodium hydroxide (NaOH)
Potassium hydroxide (KOH)
Bases are generally certain metallic oxides, metallic hydroxides and aqueous ammonia.
An acid is a proton donor, H⁺ and it interacts with water to produce excess hydroxonium ions in an aqueous solution.
The reason for this is because nonmetals, have close to fulfilling an octet and need to gain few more electrons to do this, not to lose more. Nonmetals, because of the fact they need only few more electrons to satisfy their octet they would receive or share electrons to do this.
The property that nonmetals have are that they are very electronegative, they possess a strong affinity to pull electron density closer, because they possess fewer electron shells and possess even protons this allows for this.

Hi!
The radical bromination reaction of C₆H₅CH₂CH₃ is performed through a mechanism in which radical reactions are involved. This compound is an alkylbenzene compound, and the carbon that is more reactive towards radical bromination is the carbon bonded to the aromatic ring because in the reaction mechanism the intermediaries are stabilized by resonance in the aromatic ring.
A terminal substitution will not occur because substitution there will not be stabilized by resonance. The compound that will be formed in this reaction would be:
C₆H₅CH₂CH₃ + Br₂ → C₆H₅CH₂(Br)CH₃ + HBr
Answer: Option (c) is the correct answer.
Explanation:
A physical model is defined as a model which represents how atoms are bonded together and structure of a molecule.
Physical model shows the three dimensional structure of a molecule. Physical models helps to easily understand and visualize the configuration, single bonds, double bonds and total atoms within a molecule.
Thus, we can conclude that given structure of carbonic acid best describes a physical model.
