How to make into compounds to get a formula?
Li+: Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Cu:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Pb2+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Ca2+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Al3+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Cr5+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Pb4+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Sn2+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Mn2+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
Ag+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
H+:Br-, O2-, CN-, SO3^2-, PO3^3-,MnO4-
The electrical charge on ALL compounds is zero; therefore, you write enough + ions and - ions to make th compound zero. For example,
LiBr, Li2O, LiCN, Li2SO3, Li3PO3, LiMnO4
Cu occurs as both +1 ad +2; therefore, Cu can't be done without more information.
Mn would be
MnBr2, MnO2, Mn(CN)2, MnSO3, Mn3(PO3)2.
You do the other s the same way.
To determine the formula of a compound formed between two ions, you need to consider the charges of the ions involved. The formula of the compound will reflect the ratio of ions that balance each other's charges.
For example, let's take Li+ and Br-:
1. The ion Li+ has a charge of +1, indicating that it lost one electron.
2. The ion Br- has a charge of -1, indicating that it gained one electron.
To balance the charges, we need one Li+ ion for every Br- ion. Therefore, the compound formed between Li+ and Br- is LiBr.
Using the same logic, you can apply it to the other combinations. Here are the formulas for each compound:
Li+: Lithium ion does not have a pairing ion in the given list.
Cu: The same applies here; Cu does not have the corresponding pairing ion in the given list.
