3Mq+2H3PO4 = Mq3(PO4)2+3H2
3Mq+6H+2PO4 =Mq3(PO4)2+6H
3Mq+2PO4 = Mq(PO4)2
K2O+H2SO4 = K2SO4+H2O
K2O+2H+SO4=2K+SO4+H2O
K2O+2H = 2K+H2O
AlCl3+3KOH = Al(OH)3+3KCl
Al+3Cl+3K+3OH = Al(OH)3+ 3K+3Cl
Al+3OH = Al(OH)3
MqCl2+2AqNO3 = Mq(NO3)2+2AqCl
Mq+2Cl+2Aq+2NO3 = Mq+2NO3+2AqCl
2Cl+2Aq = 2AqCl
FeCl3+3AqNO3 = Fe(NO3)3+3AqCl
Fe+3Cl+3Aq+3NO3 = Fe+3NO3+3AqCl
3Cl+3Aq = 3AqCl
