(a)
Interpretation:
The name of HBrO2 is to be stated.
Concept introduction:
Commonly, the particles possessing by chemical compounds are usually represented by chemical formulas. Besides, the chemical formula of a substance is having the
(b)
Interpretation:
The formula of tellurous acid (tellurium, Z = 52) is to be stated.
Concept introduction:
The particles possessing by chemical compounds are usually represented by chemical formulas. Besides, the chemical formula of a substance is having the symbols of element using which the chemical compound is made. Generally, in a chemical formula, the subscript number after a symbol denotes the number of atoms of the element in the formula unit of the substance. If the compound is having only one atom of an element of interest, the subscript is omitted.
