Write a balanced equation for the reaction that occurs in each of the following cases: (a) potassium metal is exposed to an atmosphere of chlorine gas. (b) strontium oxide is added to water. (c) a fresh surface of lithium metal is exposed to oxygen gas. (d) sodium metal reacts with molten sulfur.

The equations of the above reactions are shown below

Explanation:

(a)

2K(s) + Cl2(g) ==> 2 KCl(s)

(b)

SrO(s) + H2O(aq) ==> Sr(OH)2(aq)

(c)

4Li(s) + O2(g) ==> 2Li2O(s)

(d)

2Na(s) + S (l) ===> Na2S

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

level 4 to level 2 : ))
