Question

Two pure substances A and B react to form a new pure substance C. From this, we may conclude that

a. A and B are both elements

b. C is a compound, A and B may or may not be elements

c. C is an element, A and B are compounds

d. A, B, and C are all compounds

Answer 1

Compound C is formed when pure substances A and B react, and A and B can be either elements or compounds.

Step-by-step explanation:

When two pure substances A and B react to form a new pure substance C, we can conclude that C is a compound and that A and B may or may not be elements. This is because compounds are formed when two or more elements chemically combine in a fixed proportion. A compound has different properties from the elements that it contains. On the other hand, elements cannot be broken down into chemically simpler components. It is possible for A and B to both be elements or for one or both to be compounds that react to form compound C.
