Question

Which statement is true for every compound? THIS QUESTION IS WORTH 39 POINTS H.E.L.P

A.three or more elements exchange electrons

B.the compound has properties just like the original elements

C. physical forces can break it apart

D.two or more elements are chemically bonded

Answer 1

Answer: D.two or more elements are chemically bonded

Step-by-step explanation:

Compound is a pure substance which is made from atoms of different elements chemically combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. They have different properties as compared to their constituents. Example: water
`H_2O`

`2H_2O\rightarrow 2H_2+O_2`

Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper
`Cu`

Thus every compound is made up of two or more elements chemically bonded.
