I am working with cations, and anions. Are you supposed to have the subscripts balance, or the top numbers? Or both? Why would a cation of AL +3( upper corner) and an anion of PO -3 in the upper corner 3 as the subscript become a compound of AlPO3(subscri...

I have a compound of Na2subscriptCO3subscript. The cation it breaks into is NA+1 in the upper righthand corner, and the anion is CO3subscript,-2in the upper right hand corner. Where did the anion numbers come from? How can you tell what the charge is? I k...

When you have a choice of two or three ions, how do you determine which one to use in your cations/anions? Thanks!!

I think I get ionic compounds now. I'm just a bit unsure about my answers for these ones. 4. The cation is Au^3+ and the anion was SiO3subscript^-2. For the compound, I wrote (Au subscript2)subscript SiOsubscript3. Is this correct? Would it be called Gold...

How would you write out the names of NaOH, since the oxygen is before the hydrogen? I'm accustomed to writing the oxygen last.

How can Ag2Cro4 have a four on the O? Ag has a charge of two, so multiplying it by 2 would give me two, but multiplying Cr, with a charge of two (one of its few choices) by four would give me eight. How does that balance? Thank you so muh for checking on...

The name of one of the compounds given on my worksheet is Molybdenum V. But according to my periodic table, there is no MOlybdenum with a charge of 5. How could this be right? Thanks for looking into this!!

Could this be right? :AG^+1 is the cation. The Anion is SO4^-2. For the compound I wrote Ag4SO1, and in word form, I wrote Silver Sulfite. Is this right?

A water tank holds 500 gallons of water. The water is used at a rate of 12 gallons per hour. How much water is in the tank after 11 hours.

I mean like when you have an element, let's say iron, and you have the choice between choosing two and three as a charge.

ok thanks for the answer but how do you actually do it?
