Question

NaOH + H2SO4=
K2O + H2O=
Fe2O3 + HNO3=
NaOH + SO2=
Al(OH)3 + H2SO4=
SO3 + H2O=
KOH + HNO3=
MgCl2 + AgNO3

Answer 1

2NaOH + H2SO4 = Na2SO4 + 2H2O

K2O + H2O = 2KOH

Fe2O3 + 6HNO3 = 2Fe(NO3)3 + 3H2O

NaOH + SO2 = NaHSO3

2Al(OH)3 + 3H2SO4 = Al2(SO4)3 + 6H2O

SO3 + H2O = H2SO4

KOH + HNO3 = KNO3 + H2O

MgCl2 + 2AgNO3 = 2AgCl + Mg(NO3)2

Zn + 2HCl = ZnCl2 + H2

FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl

Fe(OH)3 + 3HNO3 = Fe(NO3)3 + 3H2O

NaOH + HCl = NaCl + H2O

AgNO3 + HCl = AgCl + HNO3
