Concept explainers
(a)
Interpretation:
The empirical formula of the compound that is formed by the reaction of niobium and fluorine at room temperature that contains 49.44 % of Nb by mass should be determined.
Concept introduction:
The formula of the compound that gives information about the proportions of the elements present within a compound is said to be the empirical formula. It does not represent the actual numbers of the atoms present in the compound.
(b)
Interpretation:

Concept introduction:
The reaction is said to be balanced if the number of atoms of each element on the reactant and product side is equal.
(c)
Interpretation:
The balance equation for the reaction of
Concept introduction:
