Question

Составьте уравнения реакций

CaO+SO2=

CaO+SO3=

SO2+NaOH=

SO3+NaOH=

P2O5+Ca(OH)2=

CO2+NaOH=

Answer 1

СaO + SO2 = CaSO3

CaO + SO3 = CaSO4

SO2 + 2NaOH = Na2SO3 + H2O

SO3 + 2NaOH = Na2SO4 + H2O

P2O5 + 3Ca(OH)2 = Ca3(PO4)2  + 3H2O

CO2 + 2NaOH = Na2CO3 + H2O

Answer 2

CAO+So2-CaSo3

CaO+So3-CaSo4

P2O5+CA(oh) 2

Co2+NaOH-Na2CO3+H2O
