The compound formed between F- and Cr2+ ions is written as CrF2. The compound has a 2:1 ratio of fluoride ions (F-) to chromium ions (Cr2+).
The chemical formula for sodium selenide is Na2Se.
The formula for the ionic compound formed between S^2- and Pb^4+ is PbS2, where lead (Pb) has a 4+ charge and sulfur (S) has a 2- charge. This results in the compound lead(IV) sulfide.
The formula for H plus 1 plus H minus 1 is 2H. This is because the +1 and -1 charges cancel each other out, leaving only the H atom.
The formula mass of the compound formed between Al3+ and Cl- is determined by adding the atomic masses of aluminum (Al) and chlorine (Cl), considering the charges on the ions. The formula mass would be 133.34 g/mol.
