Double Displacement Reactions

Pre$-$lab Questions: Read the relevant textbook sections and the entire lab before answering pre$-$lab questions.

For the three solutions $0\mathrm{.}1$MBa$(OH{)}_2,1MN{a}_{2}C{O}_3,$ and $2MHCl,$

a$.$ Complete and balance each double displacement reaction $($include states$)..$

b$.$ Determine whether each reaction will produce a precipitate $($ppt$),$ a gas $($gas$),$ heat $($heat$),$ or if there will be no observable reaction $($nr$),$ and write the correct abbreviation in the prediction matrix below.

$3a(OH{)}_2(aq)+,N{a}_{2}C{O}_3(aq)$

$Ba(OH{)}_2(aq{)}^{+}HCl(aq)$

$HCl(aq)+N{a}_{2}C{O}_3(aq)$

Prediction Matrix:
