(viii) The symbolic representation of one molecule of a compound is called:
The correct option is A formula
Explanation for correct option:
(A) A chemical formula is a representation of one molecule of a compound that uses chemical element symbols and numbers to convey information about the chemical proportions of atoms that make up a particular chemical compound or molecule.
Explanation for incorrect option:
(B) A depiction of a chemical process that uses element symbols to show the quantity of material in each reactant and result, generally in moles, is known as an equation. So, this is not the correct option.
(C) A chemical symbol is a one- or two-letter representation of a chemical element. The periodic table is represented with a distinct symbol for each element. So, this is not the correct option.
(D) A reactant is a material that is present when a chemical reaction begins. So, this is not the correct option.
Conclusion: Thus, option (A) is the correct answer.
