Calculate the initial molarity of Ba(OH)2 and the molarities of Ba2!, OH", and H3O! in an aqueous solution that contains 0.43 g of Ba(OH)2 in 0.100 L of solution.
How would I go about setting this problem up??
Is there an icebox involved?

Re: naming sequence
1)always name the cation before the anion. 2)Name the ligands first, in alphabetical order, and then name the metal atom or ion. Note: The metal atom or ion is written before the ligands in the chemical formula. 3)After naming the ligands, name the central metal. If the complex ion is a cation, the ...

Re: Why can h20 only donate 1 lone pair?
I think that would lead to the oxygen having a 2+ formal charge

Fe------ferrate? [ENDORSED]
In the compound [Fe(CN)6] 4- the name is hexacyanidoferrate
1)why isn't the cyanido just cyano?
2}how does the iron turn to ferrate?

charges and roman numerals
On the basis of the expected charges on the monatomic
ions, give the chemical formula of each of the following
compounds: (a) magnesium arsenide; (b) indium(III) sulfide;
(c) aluminum hydride; (d) hydrogen telluride; (e) bismuth(III)
fluoride
Can someone explain the roles of the roman numerals?

balancing reaction law
It appears that balancing the chemical equation Cu + SO2 S CuO + S would be simple if we could just add another O atom to the product side:
Cu + SO2 S CuO + S + O. (a) Why is that balancing procedure not allowed? (b) Balance the equation correctly.
I'm not sure what the actual correct answer to A is.

Net # of moles produced
The balanced equation is:
4C4H10(g) + 26O2(g) → 16CO2(g) + 20H2O(g)
How do I find the net number of moles of gas produced? My options are 6 or 5
