Na2S
The chemical formula for combining Ca2+ and AsO3^4- ions would be Ca3(AsO3)2. This shows that three calcium ions (Ca2+) will combine with two arsenite ions (AsO3^-4).
In the biuret test, the complex formed between Cu2+ and protein is a coordination complex where the peptide bonds in the protein act as ligands to chelate with the Cu2+ ions. This complexation causes a color change, typically from blue to violet or purple, indicating the presence of proteins in the sample.
The concentration of H3O+ (hydronium ions) in a solution can be calculated using the formula pH = -log[H3O+], where [H3O+] represents the molarity of the hydronium ions. This formula relates the acidity of a solution to the concentration of hydronium ions present.
Yes, Mn2+ is a cation. It has a charge of +2 because it has lost two electrons. Cations are positively charged ions formed by losing electrons.
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 compound formed by Na+ and PO43- ions is sodium phosphate, which has the chemical formula Na3PO4.
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.
The ionic compound formed from Ag+ and P3- ions would be silver phosphate. The formula would be Ag3PO4.
The compound with the formula Ag⁺ is silver ions, which have a charge of +1. Silver ions are formed when silver loses one electron.
Most likely, MX3
The formula for the compound formed between Li+ and S2- is Li2S. This is because lithium has a +1 charge and sulfur has a -2 charge, so two lithium ions are needed to balance the charge of one sulfur ion.
The compound formed when Mg^2+ and Cl^- ions react is magnesium chloride, which has the chemical formula MgCl2.
K3n
The compound formed between Mg^2+ and N^3- ions would be magnesium nitride, Mg3N2. This compound is formed by the transfer of one magnesium ion (+2 charge) and three nitrogen ions (-3 charge) to achieve a neutral charge.

The formula for sodium iodide is NaI. It is formed by the combination of sodium (Na) and iodide (I-) ions, with sodium donating an electron to iodine to form a stable compound.
