Question

1. nh₄cl = ammonium chloric
2. na₂co₃ = sodium carbon
3. h₃po₄ =
4. k₂so₄ =

Explanation:

For \(H_3PO_4\), it is a common inorganic acid. The naming of acids: if the acid contains oxygen, it is named as " - ic acid" for the common form. \(H_3PO_4\) is phosphoric acid. For \(K_2SO_4\), it is an ionic compound. The naming of ionic compounds: the cation (potassium) is named first, then the anion (sulfate). So it is potassium sulfate.

Answer:

1. Phosphoric acid
2. Potassium sulfate
