Question

Write a balanced equation for the reaction that occurs in the following A) potassium burns in atmosphere of chlorine gas B) strontium oxide is added to water C) a great surface of lithium metal is exposed to oxygen gas D) sodium metal is reacted with sulfur Write a balanced equation for the reaction that occurs in the following A) potassium burns in atmosphere of chlorine gas B) strontium oxide is added to water C) a great surface of lithium metal is exposed to oxygen gas D) sodium metal is reacted with sulfur A) potassium burns in atmosphere of chlorine gas B) strontium oxide is added to water C) a great surface of lithium metal is exposed to oxygen gas D) sodium metal is reacted with sulfur

Explanation / Answer

A) potassium burns in atmosphere of chlorine gas

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

B) strontium oxide is added to water

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

C) a great surface of lithium metal is exposed to oxygen gas

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

D) sodium metal is reacted with sulfur

16 Na(s) + S8(liq) ---> 8 Na2S(s)
