Question

Setarakan persamaan reaksi berikut
a. (NH4)2SO4(aq)+NaOH(aq)---> Na2SO4(s)+H2O(l)+NH3(g)
b. Ba(OH)2(aq)+P2O5(g)--->Ba(PO4)2(s)+H2O(l)
c. NH3(g)+O2(g)--->NO(g)+H2O(l)

Answer 1

(NH4)2SO4(aq)+2NaOH(aq)---> Na2SO4(s)+H2O(l)+NH3(g)
dimulai dr mnytakn Na 
(NH4)2SO4(aq)+2NaOH(aq)---> Na2SO4(s)+H2O(l)+2NH3(g) llu N pd amoniak 
(NH4)2SO4(aq)+2NaOH(aq)---> Na2SO4(s)+2H2O(l)+2NH3(g) llu H pd air 
yg b ada salah soal kyky
b. 3Ba(OH)2(aq)+P2O5(g)--->Ba3(PO4)2(s)+ H2O(l) muli dr barium pd barium hidroksida beri koef 3
3Ba(OH)2(aq)+P2O5(g)--->Ba3(PO4)2(s) +3H2O(l) lalu H pd air beri koef 3 jg otomatis O jg sdh setara

c. NH3(g)+O2(g)--->NO(g)+ 3/2H2O(l) mentrakan H jd pecahan 3/2 
 NH3(g)+ 2O2(g)--->NO(g)+ 3/2H2O(l) lalu O jd pechn 2 jg agarsma  jmlhny dg O pd air dn Nitrogen Monoksida
