When performing the ol' switcho-chango you get the formula Mg2O2, but Solo still marks your homework wrong. Why?
What is you didn't simplify. Always simplify ionic compounds when you can.
100
When you dissolve an acid in water, the acid will produce ____?
When you dissolve a base in water, the base will produce ____?
What is H+ ions, OH- ions
100
When group 3A elements form ions, they have lost/gained 3 electrons.
What is lost, to become "paws"-itively charged
100
Molecular compounds share electrons, and are made up of _________.
What is Molecular compounds share electrons, and are made up of nonmetals.
100
Li(ClO)
What is Lithium hypochlorite
200
Roman numerals:
What charge does lead have in this compound? PbS2
What is +4
If you work backwards, Pb as an ion will appear to have a +2 charge, and S a -1 charge. Since sulfur actually has a -2 charge, it shows that these have been reduced.
200
All acids have the same cation, what is it?
What is Hydrogen!
200
What is the correct name and formula made from a Sn+4 ion and a O-2 ion
What is Tin (IV) oxide, SnO2. Always reduce a formula when you are able to.
200
What is the correct name for N2O4. Should this formula be reduced?
What is Dinitrogen tetraoxide. If you reduce this formula it no longer fits the expected name.
200
(NH4)2O
What is ammonium oxide
300
When should an ion have -ide for an ending?
What is when it is an anion (nonmetal with a negative charge)
300
Name the acid. H3PO4
What is what is phosphoric acid
300
If a compound does not start with a metal, is there any other way it can be ionic?
What is if it starts with a cation (ex: NH4)
300
When naming molecular compounds what is done with the subscripts?
What is use prefixes to specify how many atoms there are
300
FePO4
What is Iron (III) phosphate
400
If a metal can have more than one charge, it is shown in the chemical name by using what?
What is (roman numerals) ex: (I), (II), (III), (IV)......
400
Name the acid. HI
What is hydroiodic acid
400
Explain what a binary ionic compound is.
What is a compound made up of two elements (binary), The first is a metal (cation) and the second a nonmetal (anion).
400
Name the following formula. SO3 (this is not an ion)
What is sulfur trioxide. If the first element only has one atom, don't use the prefix mono
400
Barium Phosphite
What is Ba3(PO3)2
500
If a chemical name ends in -ate or -ite, it will contain a _________ ______.
If a chemical name ends in -ide, can it ever have more than two elements?
What is Polyatomic ion (more than one element)
Yes....Hydroxide is the only polyatomic ion that might lead you to believe it is a binary compound.
500
Write a formula for the following acids.
hydronitric acid
nitric acid
nitrous acid
What is
H3N (hydro + ic acids, from binary acids ending in -ide)
HNO3 (-ic acids, from -ate)
HNO2 (-ous acids, from -ite)
500
The mystery compound AB is not an acid, and A represents the heaviest alkaline Earth metal. B represents more than one element. What do you know about this compound?
What is A is Radium, B is a polyatomic ion. The end of the name is likely -ite or -ate.
