(a)
Interpretation:
The correct formula for zinc oxide is to be determined.
Concept introduction:
The formula of an ionic compound represents the total number of ions of each element present in it.
The general rules for writing the systematic names of ionic compounds are as follows:
1) In binary ionic compounds, the name of the metal is written as the original name whereas the name of the non-metal has the root word with the suffix
2) In metals that form more than one ion, the Latin root of the metal is followed by a suffix
3) In the family of two oxoanions, the ion with more oxygen atoms has the non-metal root and a suffix
4) For hydrated ionic compounds, the total number of water molecules are represented by the Greek numerical prefixes followed by the word hydrate.
(b)
Interpretation:
The correct formula for silver bromide is to be determined.
