Answer:
f. Sn^4+
c. second
e. Al^3+
d. third
Explanation:
This question comes from a quantitative analysis showing the flowchart of a common scheme for identifying cations.
Now, from the separation scheme, Let's assume that Sn⁴⁺ & Al³⁺ were given; Then, Yes, the separation will work.
However, there will be occurrence of precipitation after the 1st step1.
So, the <u>Sn⁴⁺</u> cation will precipitate after the <u>second </u>step. Then the <u>Al³⁺</u> cation will precipitate after the <u>third</u> step.

Answer:
A
Explanation:
Isomerism is a phenomena whereby two or more organic compounds have the same molecular formula but different structural arrangements.
This means the organic compounds may belong to different organic family but the main idea is that they have different structural and spatial arrangements but the same molecular formula. This means they have the same number of each atoms
