Question

A nonmetal X is present in two forms in nature P and Q.

P is the hardest element and Q is a good conductor of electricity. X when burnt in air forms an oxide Y.Y dissolved in water forms Z. Identify X,P,Q,Y,Z and write the chemical reactions supporting your answers. What will be the action on litmus by the compound Z?

​

Answer 1

Answer:

x=carbon, a non metal

p=diamond or allotrope form of carbon

q=is graphite ,the only nonmetallic electrical conductor

Answer 2

Answer:

X- The non metal is Carbon

P- it's diamond (a crystalline form of carbon) and diamond is also the hardest element

Q- It could be Graphite or it could also be Buckminster Fullerene. They are good conductors of Electricity.

Y- it's carbon dioxide. C+O2➡CO2 which is an oxide

Z- it's carbonic acid. CO2+H2O➡H2CO3 which is an acid.

the compound Z i. e. Carbonic acid will turn litmus red as it's an acid.
