Chapter 5, Problem 48QAP

Interpretation Introduction

(a)

Interpretation:

To determine the formula of the hydrogen cyanide.

Concept Introduction:

Formula of a compound is the representation of the given name into the symbol of their element with some chemical formation of bond between them. To write the formula of a compound, we must know the symbol and valence electron of that element. The charge on the element/ molecule present is used to determine the formula of a compound.

There are two type of charge i.e. positive and negative charge species are combine together with balancing the total charge of a compound.

Answer to Problem 48QAP

Formula ofhydrogen cyanide is HCN.

Explanation of Solution

Hydrogen cyanide is formed from the two species one has negative charge and one has positive charge. H has + 1 charge and CNhas -1 charge. When two H+ and one CN- are combine together to formed HCN and net charge on the species is neutral.
