Question

Химия: Naoh+hcl= k2o+h2o= k+h2o= ca(oh)2+hno3= fe+h2so4= hcl+na2s= koh+hcl= n2o5+h2o= h2so4+ba(oh)= h2+s= fe2o3+h2=

nikTNG · Answer

NaOH+HCL= NaCl+H2O

K2O + H2O = 2KOH

2K+H2O=K2O+H

Ca(OH)2+2HNO3=Ca(NO3)2+2H2O

2Fe + 3 H2SO4 =Fe2(SO4)3 + 3H22

Na2S + 2HCl(разб.) = 2NaCl + H2S

KOH + HCl=KCl+H2O

N2O5+H2O= 2HNO3

H2SO4+Ba(OH)2=BaSO4+2H2O

H2 + S = H2S

Fe2O3+H2=FeO+H2O
