Question

When two substances A and B react, they form a substance C with the evolution of heat. The properties of C are entirely different from those of A and
B. the substance C is:
a) A compound b) An element c) A mixture d) None of the above

Answer 1

option A

"it's a compound"

Explanation:

Since the substance C is a mixture of two substances, it may either be a mixture or a compound

In a mixture the constituents retain their properties while in a compound, they lose their properties.

Since the question mentions that C has different property from both A and B, hence it must be a compound
