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

Mar 15, 2017

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:

${H}_{2} \left(g\right) + \frac{1}{2} {O}_{2} \left(g\right) \rightarrow {H}_{2} O \left(l\right)$

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

Or, ${C}_{6} {H}_{12} {O}_{6} \left(s\right) + 6 {O}_{2} \left(g\right) \rightarrow 6 C {O}_{2} \left(g\right) + 6 {H}_{2} O \left(l\right)$

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