O acid-base neutralization O precipitation O redox O none of the above O acid-base neutralization O precipitation O redox O none of the above Caols) + cole) CaCO,(s) O acid-base neutralization O precipitation O redox O none of the above KOH(aq) + AgNO,(aq) KNO3(aq)+Ag()H(s) O acid-base neutralization O precipitation O redox O none of the above Ba(OH)2(aq) + 2HNO,(aq) O acid-base neutralization O precipitation O redox O none of the above Ba(NO2)2(aq) + 2H20(2)

Explanation / Answer

Ba(ClO3)2 (s) ----> BaCl2 (s) + 3O2 (g)

Answer : redox reaction.

Cl5+ is reduced into Cl- and O2- is oxidized into O.

2 NaCl (aq) + K2S (aq) ----> Na2S (aq) + 2 KCl (aq)

Answer : none of the above

( It is just cation / anion exchange reaction), There is no reduction/oxidation, No precipitaion, and there is no acid / base in this reaction.

CaO (s) + CO2 (g) ----> CaCO3 (s)

Answer : Acid-Base neutralization reaction.

Lux-Flood: an acid is an O2- acceptor, and a base is an O2- donor

CaO is oxide ion donor - Base

CO2 is oxide ion acceptor - Acid

KOH (aq) + AgNO3 (aq) ----> KNO3 (aq) + AgOH (s)

Answer : Precipitation reaction

one of the product is precipitate and there is no solid reactant .

Ba(OH)2 (aq) + 2 HNO2 (aq) ---> Ba(NO2)2 (aq) + 2 H2O(l)

Answer : Acid - base neutralization

Ba(OH)2 is Base

HNO2 is acid
