Question

pair. 40. Write a neutralization reaction for each acid and base pair. (a) HF(aq) and Ba (OH)2(aq) (b) HCIO4 (aq) and NaOH(aq) (c) HBr(aq) and Ca (OH)2(aq) (d) HCl (aq) and KOH (aq) h met- 42. Write a balanced chemical equation showing how each met- al reacts with HCl. (a) K (b) Ca (c) Na (d) Sr w each 44. Write a balanced chemical equation showing how each met- al oxide reacts with HCl. (a) SrO (b) Na2O (c) Li2O (d) BaO 46. Predict the products of each reaction. (a) HI (aq) Al(s) (b) H2SO4 (aq) Tio20s) (c) H2CO3 (aq) LiOH (aq)

Explanation / Answer

46) a ) 6 HI ( aq) + 2Al (s) -----------> 2AlI3 ( s) + 3H2 (g)

b)2 H2SO4 ( aq) + TiO2 (s) -------------> Ti(SO4 ) 2 (s) + 2 H2O (l)

c) H2CO3 (aq) +2 LiOH (aq) ------------> Li2CO3(aq) + 2 H2O (l)

40 ) a)  2HF(aq) + Ba(OH)2(aq) ------------> BaF2 (aq) + 2H2O(l)

b) HClO4 (aq) + NaOH (aq) --------------> NaClO4 (aq) + H2O(l)

c)2 HBr(aq) + Ca(OH)2 -----------------> CaBr2 (aq) + 2H2O (l)

d) HCl (aq) + KOH (aq) ------------> KCl (aq) + H2O (l)
