Concept explainers
(a)
Interpretation:
Empirical formula of the given compound should be determined.
Concept introduction:
Number of moles is equal to the ratio of mass to the molar mass. The mathematical expression is given by:
Number of moles = massmolar mass
Empirical formula is defined as the formula in which proportions of elements are present in a compound rather than actual number of atoms.
(b)
Interpretation:
A plausible equation for the reaction should be written.
Concept introduction:
Plausible equation is the equation in which all the atoms present in the reaction should be balanced and the charge of reaction or equation should be neutral.
Cupric ion is the only positive ion and chromate ion and hydroxide ion are negative ion.
