Which of the following is not a characteristic of a compound - has different properties from the elements that formed it or different samples have different properties?

Answer 1

Different samples of a compound will not have different properties, that is a characteristic of a rough mixture. Different samples of a compound will have the same properties.

Answer 2

the properties of compounds differ from the elements that make up that compound. Other than the example stated above, another good example would be the table salt you use everyday, sodium chloride (Na Cl)

As you know know, sodium is from Group I in the Periodic Table. It is a soft silvery metal at room temperature. Sodium is relatively a reactive metal. When added to water or acids, it reacts explosively.

Chlorine, on the other hand, is from Group VII. It is a greenish yellow gas at room temperature. It is a poisonous gas, able to choke people to death.

But when reacted together, sodium and chlorine forms sodium chloride, which is safe to use.

So you can conclude that that the properties of a compound and its elements may vary completely from the elements that make it up. Water is another goo example (H20)
