Question

Which is a chemical property of mercury? boiling point of −39¨¬C silvery color liquid at room temperature reacts with oxygen

Answer 1

liquid at room temperature

Answer 2

Reacts with oxygen

Step-by-step explanation:

Hello,

In this case, we refer to chemical properties as those changing the composition of the initial substances, in such a way, for the given options, it is easy to notice that the boiling point is physical property because it changes its state, not the composition. Moreover, the silvery color is also a physical property in terms of the appearance as well as the liquid at room temperature because it is the segregation state at room temperature.

Therefore, since a chemical reaction is carried out when mercury reacts with oxygen that is the chemical property as the mercury turns into mercury (II) oxide:

`2Hg+O_2\rightarrow 2HgO`

Best regards.
