Hope this helps.
Answer : The correct answer is Option D.
Explanation:
Ores are defined as natural occurring substance from which metals and another mineral are extracted.
Bauxite is primary ore of an aluminium metal. it doesn't have definite or specific chemical composition. This is because it contains mixture of hydrous aluminum oxide, aluminum hydroxides, insoluble materials like hematite, quartz ,geothite ,magnetite etc.
From the given options the most appropriate statement which is correct about the bauxite is 'It does not have a definite chemical composition'.
Hence, the correct option Is (D).

Answer:
See explanation
Explanation:
We know that
%ic of the interatomic bond = [1 - e^-(XA - XB)^2/4] * 100%
Now;
XA = electronegativity of Ti = 1.61
XB = electronegativity of Al = 1.54
Substituting values;
%ic of the interatomic bond = [1 - e^-(1.61 - 1.54)^2/4] * 100%
%ic of the interatomic bond = 0.12%
Given the low %ic of the interatomic bond, the bond is metallic.
