Question

15/30 name the compound (nh₄)₂cro₄ type your answer...

Explanation:

Step1: Identify the ions

The compound \((NH_4)_2CrO_4\) consists of the ammonium ion \(\text{NH}_4^+\) and the chromate ion \(\text{CrO}_4^{2-}\).

Step2: Determine the ratio of ions

To balance the charges, we need 2 ammonium ions (each with a +1 charge) to balance the -2 charge of the chromate ion.

Step3: Name the compound

Using the rules for naming ionic compounds, we name the cation first (ammonium) and then the anion (chromate). So the name of the compound is ammonium chromate.

Answer:

ammonium chromate
