What formula for a compound has monatomic and polyatomic ions present?
HannahAllenfb6039
The answers have to be include monatomic and plyatomic ions present and ratio between positive and negative ions is one to two, and a group IIA element that loses one half of its total electrons upon ion formation is present, and the sum of the atomic numbers for the two elements involved in the polyatomic ion is 13.

How should more than one polyatomic ion be indicated in a chemical formula?
One reason is that the composition of a polyatomic ion is fixed, just as that of a compound is fixed. If more than one polyatomic ion is present in an ionic compound, the use of parentheses allows a subscript to be used after the right parenthesis to designate the number of ions just as such subscript is used to designate the number of atoms in a compound.
What is the molecular formula of a compound given that molar mass of the compound is 30.04 gram and the empirical formula is NH?
The molecular formula of this compound is N2H2. This is obvious because the empirical formula of a compound is the lowest positive integer ratio of atoms present.

Which polyatomic ion forms a neutrak compound when combined with a group 1A monatomic ion in a 1 1 ratio?
Since Group 1A monatomic ions have a charge of 1+, only a polyatomic ion with a charge of 1- can combine to form a compound in which the monatomic ions and polyatomic ions are present in a 1 to 1 ratio. The following polyatomic ions with a charge of 1- can form a neutral compound when combined with a group of 1A monatomic ion in a 1 to 1 ratio.acetate - C2H3O2-bicarbonate (or hydrogen carbonate) - HCO3-bisulfate (or hydrogen sulfate) - HSO4-chlorate - ClO3-chlorite - ClO2-cyanate - OCN-cyanide - CN-dihydrogen phosphate - H2PO4-hydroxide - OH-nitrate - NO3-nitrite - NO2-perchlorate - ClO4-permanganate - MnO4-thiocyanate - SCN- Source: http://chemistry.about.com/od/chartstables/tp/common-polyatomic-ions.htm
