How many hydrogen atoms are present in one molecule of hydrochloric acid (HCl)?
A
0
B
4
C
2
D
1
Verified step by step guidance1
Identify the chemical formula of hydrochloric acid, which is HCl.
Understand that the subscript in a chemical formula indicates the number of atoms of that element in one molecule.
Note that in HCl, there is no subscript after H, which means there is exactly one hydrogen atom.
Similarly, there is one chlorine atom indicated by the absence of a subscript after Cl.
Conclude that one molecule of hydrochloric acid contains exactly one hydrogen atom.
