Question

Classify each of these reactions. label what the reactions are if there REDOX, acid-base nuetralization, percipitation

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

CH₄(g) + 2O₂(g) -------> CO₂(g) + 2H₂O(l)

2AgNO₃(aq) + Zn (s) ------> Zn(NO₃)₂ (aq) + 2Ag(s)

(NH₄)₃PO₄(aq) + AlCl₃(aq) -----> AlPO₄(s) + 3NH₄ Cl(aq)

Please mark each reaction with the correct classification if you can please explain this is due today thank you :)

Answer 1

NaOH(aq) + HClO4 (aq) ------> NaClO4(aq) + H2O(l)
NaOH is base and HClO4 is acid
Also there is product as H2O
So, it is acid base neutralisation reaction

CH4(g) + 2O2(g) -------> CO2(g) + 2H2O(l)
this is redox reaction
Oxidation satte of H is CH4 is -1 and that in water is +1. So, H is oxidised
oxidation state of O in O2 is 0 and that is H2O is -2. So, O is reduced
Since reduction and oxidation is taking place here, it is a redox reaction.

2AgNO3(aq) + Zn (s) ------> Zn(NO3)2 (aq) + 2Ag(s)
This is also redox reaction
Ag is reduced and Zn is oxidised

(NH4)3PO4(aq) + AlCl3(aq) -----> AlPO4(s) + 3NH4 Cl(aq)
This is precipitation reaction as solid is formed in product
