Final answer:
The task is to rank materials by density and identify which one's density is similar to strontium using periodic trends and empirical data.
Step-by-step explanation:
The question involves ranking the densities of materials to identify composition and probable similarity to the density of strontium. Density is an intensive property of matter that can be used to distinguish between substances. Elements with similar properties to strontium will likely have similar densities. To predict the densities of given elements or substances, one can refer to periodic trends and empirical data such as provided tables of density.
For instance, to determine which element has a density most and least similar to strontium, you would typically look at elements in the same group on the periodic table because they tend to have similar properties. Also, similar phases of matter and atomic mass can give clues about density comparisons.
When faced with the task of distinguishing sodium chloride from strontium chloride, one could use a chemical test, look for differences in solubility, or measure a physical property like density. Each compound's unique characteristics will guide you to the correct identification.
