1.	9. (a) What is a chemical formula ? (b) What is thesignificance of a formula ? Give an example to illustrate.
Answer» Answer: A chemical FORMULA is a way of presenting information about the chemical proportions of atoms that CONSTITUTE a particular chemical compound or molecule, USING chemical element symbols, NUMBERS, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus signs A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. In empirical formulae, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound, by ratios to the key element. Example - Salt - NaCl , ethanol C2H6O because the molecule of ethanol contains TWO Carbon, 6 Hydrogen and 1 Oxygen atom Explanation: Hope it helps you !
