Write formulas for the compounds that form from In and each of the following polyatomic ion: NO−3, SO2−4, PO3−4.
(Assume In charge is 3+.)
In(+3 charge)
NO3(-1 CHARGE)
SO4(-2 charge)
P4(-3 charge)
Re posting this a little differently. hopefully someone can help me answer this now. Please post to this question. Thank you.
If you understand the post below you will know how to do this. I'll check your answers.
no i don't understand the post below or what one you are referring to. i gave my work in the original posting already.
To write the formulas for the compounds that form from In and each of the given polyatomic ions, we need to determine the charges of In in the compounds.
From the question, it is given that In has a charge of +3 (In3+). Now we need to find the proper combination of In with each polyatomic ion to balance the charges.
1. In and NO3-:
The charges need to balance out, so we can use three NO3- ions to combine with one In3+ ion. This results in the formula In(NO3)3.
2. In and SO4^2-:
Again, the charges need to balance, so we need two In3+ ions to combine with three SO4^2- ions. The resulting formula is In2(SO4)3.
3. In and PO4^3-:
To balance the charges, we need three In3+ ions to combine with two PO4^3- ions. The formula for this compound is In3(PO4)2.
So, the formulas for the compounds formed from In and the given polyatomic ions are:
1. In(NO3)3
2. In2(SO4)3
3. In3(PO4)2
