When solutions of barium chloride and lithium sulfate are mixed, t the reaction are he spectator ions in A) Li and Cl. B) Li and Ba2* C) Cl and SO42 D) No spectator ions. E) Ba2 and SO2 18. A piece of magnesium metal is burned in air (containing oxygen gas), and a white powder of magnesium oxide is formed. The class of this reaction is: A) combination reaction B) double-displacement reaction. C) decomposition reaction. D) single-displacement reaction. E) disproportionation reaction 19. Which of the following ions can act as Bronsted base(s)?Explanation / Answer
Mn(s) + O2(g)- MnO2
