(a)
Interpretation:
The systematic name for the formula
Concept introduction:
Polyatomic ions are those in which atoms of more than one elements are present. Generally, the majority of the polyatomic ions are oxoanions in which a non-metal is bonded to one or more oxygen atoms.
The general rules for naming a family of two oxoanions are:
1) The ion with more oxygen atoms takes the non-metal root and the suffix
2) The ion with fewer oxygen atoms takes the non-metal root and the suffix
(b)
Interpretation:
The systematic formula for potassium dichromate is to be determined.
Concept introduction:
The general rules for naming oxoanion compounds are:
1) The ion with the most number of oxygen atoms has the
2) The one with one less oxygen atom does not have the
3) The ion with two fewer oxygen atoms has just the root and the suffix
4) The ion with three fewer oxygen atoms has the prefix
(c)
Interpretation:
The systematic name for

(d)
Interpretation:
The systematic formula for potassium carbonate dihydrate is to be determined.
Concept introduction:
The general rules for naming ionic compounds are:
1) The names and formulas give the positive ion first and the negative ion second for all ionic compounds.
2)For binary ionic compounds, the cation name is the same as that of the metal whereas the anion name has the suffix

- Draw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
