Why couldn't Mendeleev predict the existence of the noble gases in the periodic table of elements?
He could predict other elements because there was an obvious gap, but he couldn't predict the noble gases because he didn't realize that there was going to be an 18th group since none of them were yet discovered. When he first started organizing the periodic table, the pattern still made sense even without the noble gases.
What 2 elements composes iron oxide?
I would hope that "chromium" is obvious. Slightly less obvious is that "oxide" refers to the presence of oxygen.
How can you use classification to tell how closely organisms are related?
Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.

Why did Mendeleev called his arrangement of elements the periodic table?
If the elements (which were discovered by his time) were organized in the increasing order of their atomic weight, they will exhibit an apparent periodicity of properties. It also had the ability to predict physical and chemical properties of some undiscovered elements.
