Capitolo 2, Problema 80c
Assume that you encounter the following sentences in your reading. What is the chemical formula for each substance mentioned? (c) Hydrogen cyanide is a very poisonous gas.
Guida verificata passo dopo passo1
Identify the elements present in the compound mentioned. In this case, hydrogen cyanide contains hydrogen (H), carbon (C), and nitrogen (N).
Understand the naming convention. The 'cyanide' part of hydrogen cyanide refers to a CN group, which is a common way to denote a cyanide ion.
Determine the chemical formula for the cyanide ion. Cyanide ion is composed of one carbon atom and one nitrogen atom, forming a CN- ion.
Combine the elements according to their stoichiometry in the compound. Since it is hydrogen cyanide, it consists of one hydrogen atom and one cyanide ion.
Write the chemical formula by placing the symbols of the elements and their respective quantities next to each other. For hydrogen cyanide, this would be HCN.
