Answer:
compound identification is unknown B
Step-by-step explanation:
It is not possible to determine whether the two compounds you have described are the same or not based on the information provided. The percentage of each element in a compound can be used to determine the compound's empirical formula, but it does not necessarily give information about the compound's molecular structure or identity.
For example, two compounds could have the same empirical formula (i.e., the same proportions of elements) but have different molecular structures, resulting in different chemical and physical properties. Alternatively, two compounds could have different empirical formulas but the same molecular structure, resulting in the same chemical and physical properties.
Without more information about the chemical and physical properties of the compounds, it is not possible to determine whether they are the same or not.
