Chapter 2, Problem 69QP
Interpretation Introduction
Interpretation:
The ratio of the atoms in the given molecular formula is to determined and also the characteristics of chemical formula is to be discussed.
Concept introduction:
The way of presenting information about the chemical proportions of atoms that constitute a given chemical compound or molecule is termed as chemical formula.
Chemical formula uses element symbols, numbers, and also some other symbols, such as dashes, plus (+) and minus (−) signs and parentheses.
Ionic compound are the compounds thatconsist ofions.
Atoms that gain or lose electrons, giving them a net positive or negative charge are known as ions. Positively charged ion is termed as cation whereas anion is negatively charged ion.
