Question

A non-metal X exists in two different forms Y and Z. Y

is the hardest natural substance, whereas Z is a good

conductor of electricity. Identify X, Y and Z.

2. X + YSO4——-> XSO4+ Y

Y + XSO4 ——–> No reaction

Out of the two elements, ‘X’ and ‘Y’, which is more

reactive and why?

Please no spam
i need full explanation ​

Answer 1

Answer:

X is Carbon

Y is Diamond

Z is Graphite

Z which is Graphite is more electrical conductive because Diamond which is Y is tetrahedron in structure

whereas graphite had polyhedron in structure.

Z can conduct electricity.

X is more reactive than Y because as we can see in the above two reactions that X can replace Y from its compound where as Y cannot.

Hope it helps....
