Chapter 13.6, Problem 13.9P

(a)

Interpretation Introduction

Interpretation:

Formula for beryllium carbonate tetrahydrate has to be identified.

Concept Introduction:

Formula for names of molecules is determined as follows:

1 Identify the symbol of elements present in the name of molecule.

2 Identify the oxidation state of each element present in the name of molecule.

3 Number of oxidation state is cross multiplied as number of atoms in the formula to neutralize the charge.

4 Identify the number of water molecules by prefix used for hydrate in the name of hydrate.

5 Identify prefix that decides the number of water molecules is as follows:

$\begin{array}{cc}\text{Prefix}& \text{Number of water molecules}\\ \text{mono}& \text{1}\\ \text{di}& \text{2}\\ \text{tri}& \text{3}\\ \text{tetra}& \text{4}\\ \text{penta}& \text{5}\\ \text{hexa}& \text{6}\\ \text{hepta}& \text{7}\\ \text{octa}& \text{8}\\ \text{nona}& \text{9}\\ \text{deca}& \text{10}\end{array}$
