Question

What is the chemical name of $M{{n}_{3}}{{\left( B{{O}_{3}} \right)}_{2}}$ ?

Answer 1

Hint : A chemical formula is a method of presenting information about the chemical proportions of atoms that make up a specific chemical compound or molecule by using chemical element symbols, numbers, and, in some cases, other symbols such as parentheses, dashes, brackets, commas, and minus signs.

Complete Step By Step Answer:
The process of naming binary (two-element) molecular compounds is similar to the process of naming simple ionic compounds. The first element in the formula is simply listed with the element's name. The second element is named by taking the element name's stem and appending the suffix -ide. The number of atoms in a molecule is specified using a system of numerical prefixes.
There are a few exceptions to the rule that the less electronegative element is written first in the formula. Carbon is always the first element in a formula, and hydrogen comes after nitrogen in a formula like NH3. In binary compound formulas, common nonmetals are listed in the following order: $C$ , $P$ , $N$ , $H$ , $S$ , $I$ , $Br$ , $Cl$ , $O$ , $F$ .
When the element's name begins with a vowel, the an or o at the end of the prefix is usually dropped from the name. Four oxygen atoms, for example, are tetroxide rather than tetraoxide.
If there is only one atom of the first element in a molecule, the prefix "mono" is not added to its name.
$M{{n}_{3}}{{\left( B{{O}_{3}} \right)}_{2}}$ is the chemical name of Manganese(II) Borate. Its molar mass is 282.4325.

Note :
Acids are named after their anion, which is the ion that is attached to the hydrogen. One ion is attached to hydrogen in simple binary acids. The prefix "hydro-," the nation's first syllable, and the suffix "-ic" is used to name such acids. Oxygen is present in complex acid compounds. For an acid containing a polyatomic ion, the ion's suffix "-ate" is replaced with "-ic."
