Photochemical equivalence law
<u>Answer:</u>
1- Ba(ClO3)2(s) ----> BaCl2(s) +3O2(g) -Redox
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)+ AgNO3(aq) -----> KNO3(aq) + AgOH(s) - Precipitation
5- Ba(OH)2(aq) + 2HNO2(aq) -----> Ba(NO2)2(aq) +2H2O(l) -Neutralization.
<u>Explanation;</u>
1) Redox, because it involves bith reduction and oxidation
2) I suppose would be "none of the above" for this chemical reaction, from the choices given.
3) It is a synthesis reaction, thus the correct answer should be "none of the above" from the asker's choices.
4) It is a precipitation reaction, also called double decomposition reaction where two soluble salts react to form an insoluble salt and a soluble salt.
5) It is acid-base neutralization, as such reactions form both a salt and water.
