Respuesta :

A compound is consists of an anion and a cation. A cation is a positively charged ion while an anion is a negatively charged ion. When the two are combined, an exchange of charges takes place that reflects on the subscripts of the ions. In this case, the resulting compound is Cr(OH)3. This is called chromium(III) oxide.

Answer:

Chromium (III) hydroxide

Explanation:

Hello! Let's solve this!

We see that Chromium is with its valence number +3, and hydroxy is with its valence number -1. So, for the loads to be balanced we need 3 hydroxyls.

So the molecule looks like this:

Cr (OH) 3

Due to hydroxyl, it is called hydroxide and since it is Chrome, then the compound is called:

Chromium (III) hydroxide
