Interpretation :
Difference between a coefficient and a subscripts in a chemical must be explained with examples of each.
Concept Introduction :
In chemical equation formula of compounds are given along with the physical states. Coefficients and subscripts can be found in chemical equation. Coefficients are the number written before each species and subscripts are the numbers written for all the elements in a compound.
Answer to Problem 3RQ
A coefficients represents the number of moles of the species whereas a subscript represents the number of a particular atoms present per molecule.
Explanation of Solution
Coefficients in
In this reaction it is clear that 2 moles of HCl is required per mole of CaCO3. Thus coefficient of HCl is 2. ‘2’ in CaCl2 is the subscript of Cl which represents that there are 2 Cl atoms in 1 CaCl2 molecule.
