Answer: Solution in Water
Explanation:
I believe this refers to the reaction between Zinc and Hydrochloric acid.
When this happens, the solution will be Zinc Chloride but as it happened in a solution (the acid), the resulting Zinc Chloride salt would be in aqueous form which means that it would be a solution in water which is the other product of this reaction.
Had the zinc reacted with gaseous HCI, it would have resulted in a Zinc Chloride with no liquid in it.
Answer: Proteins
Explanation:
Proteins are one of the most plentiful naturally-grown molecules in living systems and possess the most distinctive extent of duties of all macromolecules. The purposes of proteins are highly distinct for 20, unlike chemically different amino acids that develop large chains, plus the amino acids can occur in any method. Proteins may be architectural, regulatory, contractile, or shielding; they may work in transportation, storage, or membranes; or they may be poisons or enzymes. An instance of the function of proteins: proteins can work as enzymes or hormones. Enzymes made by living cells are catalysts in biochemical reactions and are usually proteins.
