Solution 1

The oxidation state of Cr in CrO5 is +6.

Here's how you can determine this:

  1. Oxygen usually has an oxidation state of -2.

  2. In CrO5, there are five oxygen atoms, so the total oxidation state for all oxygen atoms is -2 * 5 = -10.

  3. The sum of the oxidation states in a neutral compound is ze Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
