Answer:
A) 2 upper Hg upper O (s) right arrow 2 upper H g (l) plus upper O subscript 2 (g).
Explanation:
Elements or compounds can be combined or degraded to form new substances called PRODUCTS. In chemistry, the state in which the substances reacting or being formed are is represented using signs in brackets.
(s) means solid state
(aq) means aqueous state
(l) means liquid state
According to this question, in the reaction between: 2 upper Hg upper O (s) right arrow 2 upper H g (l) plus upper O subscript 2 (g). This can be chemically written as:
2HgO (s) → 2Hg (l) + O2 (g)
From this equation, it can be observed that Mercury (Hg) and oxygen (02), which are the products are in a liquid and gaseous state respectively as shown by the sign.
