Решите пожалуйста химические формулы K2O+H3PO4 - Na2O+HPO3 - MgO+HNO3 - BaO+H2S - Al2O3+H2SO4 - Cr2O3+HPO4 -

Answer 1

Ответ:3K2O + 2H3PO4 --> 2K3PO4 + 3H2O

Na2O +2 HPO3 -->2NaPO4 + H2

MgO+ 2HNO3--> Mg(NO3)2 + H2O

BaO + H2S ---> BaS + H2O

Al2O3 + 3H2SO4--> Al2(SO4)3+3 H2O

Cr2O3 + H3PO4--> CrPO4 + 3H2O
