(a)
Interpretation: The chemical formula and molecular (formula) mass of ammonium sulfate are to be interpreted.
Concept Introduction: An ionic compound is composed of cation and anion. Here, the cation is positively charged, and the anion carries a negative charge.
The cation and anion can be composed of more than one atom. Such type of ions is called polyatomic ions. The chemical formula of an ionic compound can be interpreted with the help of the criss-cross method.
(b)
Interpretation: The chemical formula and molecular (formula) mass of sodium dihydrogen phosphate are to be interpreted.

- Soap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
