Answer:
The answer to your question is below
Explanation:
Data
Aqueous acetic acid
Aqueous barium hydroxide
Formula
Acetic acid CH₃CH₂COOH
Barium hydroxide Ba(OH)₂
Neutralization reaction
CH₃CH₂COOH + Ba(OH)₂ ⇒ Ba( CH₃CH₂COO)₂ + H₂O
Barium acetate + H₂O
Barium acetate = Ba( CH₃CH₂COO)₂ = Ba(C₃H₅O₂)₂
TABLE SALT IS A SUBSTANCE.
In chemistry, a substance refers to a matter which has specific composition and specific properties which do not change. A substance can be an element or a compound. A substance typically has a constant composition, which can not be separated by physical methods.
In the question given above, table salt is an example of a chemical substance because, it has a constant specific composition and its components can not be separated by physical methods.
Seawater and sand are not substances, because they have varied compositions and their components can be separated by physical methods.
