Classify each of these reactions.

1)ba(clo3)2(> bacl2(s)+3o2(g)

2)2nacl(aq)+k2s(> na2s(aq)+2kcl(aq)

3)cao(s)+co2(> caco3(s)

4)koh(aq)+agcl(> kcl(aq)+agoh(s)

5)ba(oh)2(aq)+2hno2(> ba(no2)2(aq)+2h2o(l)

each classified reaction should be one of these:

acid-base neutralization

precipitation

redox

none of the above

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

2)2NaCl(aq)+K2S(aq)--->Na2S(aq)+2KCl(aq)  - None of the above

3)CaO(s)+CO2(g)--->CaCO3(s)  - None of the above

4)KOH(aq)+AgCl(aq)>KCl(aq)+AgOH(s) -precipitation reaction

5)Ba(OH)2(aq)+2HNO2(aq)--->Ba(NO2)2(aq)+2H2O(l)  - Acid-base neutralization reaction

In this reaction, chlorine is reduced and oxygen is oxidized. Both reduction and oxidation occur in this reaction. Therefore, this is a redox reaction.

In this reaction, both Na2S and KCl are soluble in water. Therefore the reaction is non of the above. Since it can not be a double displacement reaction in which two compounds react and cations and anions exchange their places to form new compounds.

In this reaction CaO and CO2 combine to form calcium carbonate. This is a synthesis reaction, and thus its none of the above choices

In this reaction, the salt KCl is soluble in water and AgOH is insolubel in water. Therefore, this is a precipitation reaction.

In this reaction, nitrous acid acts as an acid and barium hydroxide acts as a base. Therefore, barium hydroxide and nitrous acid react to form salt and water. Therefore, this reaction is acid-base neutralization reaction.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

lol for the pointsss
