Question

A compound is a pure substance that is composed of more than one type of element. Which of the following statements is true of compounds?

Compounds can be decomposed into their component parts through physical processes.

There is only one type of compound, so they all have similar characteristics and compositions.

Compounds have definite chemical compositions that can be described by chemical formulas.

Compounds have properties which are identical to the properties of their component elements.

Answer 1

Compounds are pure substance made of more than oe type of element and are ....?

Answer 2

First, for future reference, this is sort of more of a chemistry question.

Second, the third is true. Take water for example. You can't just pull water apart; it has to be split by chemical processes, so A isn't true. Water is very different from any other chemical compound--take hexane or toluene for example. Thus B isn't true. Water doesn't act like either Hydrogen or Oxygen, so D isn't true. However, Water does have a definite chemical composition that can be described by a chemical formula: the famous H2O.

Answer 3

A compound can't be a pure substance.
