How do I write the formula for the following compounds?
1.potassium permanganate
2.chromium (VI)cyanide
3. tin (II) sulfite
4. vanadium (V)fluride
5. ammonium nitrate
Can you help me figure these out i am having a hard time trying to work the problems out
I'm doing these for you BUT you need to learn to do them yourself. Tell me what you don't understand about writing formulas and I can help you learn to do them. It's really very simple; it only requires that you can count to 10. I know you can do that.
KMnO4
Cr(CN)6
SnSO3
VF5 (that's fluoride), pronounced flue o ride).
NH4NO3
Certainly! I can help you with writing the formulas for these compounds. To write the chemical formulas, you need to understand the symbols and charges of the individual elements present in the compounds.
1. Potassium permanganate:
- The symbol for potassium is K, and its charge is +1.
- The symbol for permanganate is MnO4^-, and its charge is -1.
To balance the charges, you need one potassium ion and one permanganate ion. The formula for potassium permanganate is KMnO4.
2. Chromium (VI) cyanide:
- The symbol for chromium is Cr.
- The charge of chromium in this compound is +6.
- The symbol for cyanide is CN^-, and its charge is -1.
To balance the charges, you need one chromium ion and two cyanide ions. However, since the charge of chromium is +6, you need to write the Roman numeral in the compound's name. The formula for chromium (VI) cyanide is Cr(CN)6.
3. Tin (II) sulfite:
- The symbol for tin is Sn.
- The charge of tin in this compound is +2.
- The symbol for sulfite is SO3^2-, and its charge is -2.
To balance the charges, you need one tin ion and one sulfite ion. However, since the charge of tin is +2, you need to write the Roman numeral in the compound's name. The formula for tin (II) sulfite is SnSO3.
4. Vanadium (V) fluoride:
- The symbol for vanadium is V.
- The charge of vanadium in this compound is +5.
- The symbol for fluoride is F^-, and its charge is -1.
To balance the charges, you need one vanadium ion and five fluoride ions. However, since the charge of vanadium is +5, you need to write the Roman numeral in the compound's name. The formula for vanadium (V) fluoride is VF5.
5. Ammonium nitrate:
- The symbol for ammonium is NH4^+, and its charge is +1.
- The symbol for nitrate is NO3^-, and its charge is -1.
To balance the charges, you need one ammonium ion and one nitrate ion. The formula for ammonium nitrate is NH4NO3.
Remember, when determining the formulas of compounds, it is important to balance the charges of the ions to achieve overall neutrality. I hope this helps!
