10.68
a) 2 HBr(s) + Ca(OH)2(aq) -------------- CaBr2(aq) + 2 H2O(l)
Acid-base neutralisation reaction
b) Cl2(g) + 2 KBr(s) -------- 2KCl(s) + Br2(g)
single replacement
c) 2 Na3PO4(aq) +3 Mg(NO3)2(aq) ---------------- 3 NaNO3(aq) + Mg3(PO4)2(s)
Double replacement precipitation reaction
d) Mg(s) + Cl2(g) ---------- MgCl2(s)
It is combination reaction
10.69
a) 2 HgO(s) ------------ 2 Hg(l) + O2(g)
It it combination reaction
b) AgClO4(aq) + LiCl(aq) ------------ AgCl(s) + LiClO4(aq)
It is double replacement precipitation reaction
c) K2CO3(g) + HNO3(g) ------------- KNO3(aq) + CO2(g) + H2O(l)
It is the liberation of gas reaction
d) C6H12O6(s) + 6 O2(g) -------------- 6 CO2(g) + 6H2O(g)
It is the combustion reaction.
