Problem
Solid MgCO3 is added to excess aqueous HCl in a flask. The gas produced is immediately bubbled into a second flask containing aqueous Ca(OH)2, forming a white solid in that flask. Which pair correctly identifies the predominant reaction type in the first flask and in the second flask, respectively?
(a) Acid–base neutralization followed by precipitation reaction
(b) Gas-evolution reaction followed by acid–base neutralization reaction
(c) Gas-evolution reaction followed by precipitation reaction
(d) Acid–base neutralization reaction followed by acid–base neutralization reaction
