Question

закончить уравнения
H2SO4+NaH
K2CO3+CaCL2
H3PO4+KOH

Answer 1

2 NaOH + H2SO4 = 2 H2O + Na2SO4
K2CO3 + CaCl2 = 2 KCl + CaCO3
H3PO4 + 3 KOH = 3 H2O + K3PO4

Answer 2

H2SO4+2NaOH=Na2SO4 +2H2O
K2CO3+CaCL2= CaCO3 + 2KCl
H3PO4+KOH

Answer 3

H2SO4+2NaOH=Na2SO4 +2H2O
K2CO3+CaCL2= CaCO3 + 2KCl
H3PO4+3KOH=K3PO4+3H2O
