Question

Do compounds have the same physical properties as their elements? What about chemical properties?

Answer 1

Compounds have NEITHER the same chemical properties NOR the same physical properties as their constituent elements.

Explanation:

And this is a characteristic of chemical change. And we could use many reactions to demonstrate this principle:

`H_2(g) + 1/2O_2(g) rarr H_2O(l)`

Under standard conditions, the reactants are colourless gases, and the products are colourless liquids.

Or, `C_6H_12O_6(s)+6O_2(g) rarr 6CO_2(g) + 6H_2O(l)`

You should be able to supply many more reactions that demonstrate the difference between chemical and physical properties of reactants and products.
