Question

Химия: 1) so2+ 3o3 2)fe +cl2 -- fecl3 3)zn+hcl -- zncl2+h2 4)2mg+o2=mgo 5)3na+h2o = 3naoh + h2

brll1bellrf43 · Answer

2SO₂ + O₂ = 2SO₃2Fe + 3Cl₂ = 2FeCl₃Zn + 2HCl = ZnCl₂ + H₂2Mg + O₂ = 2MgO2Na + 2H₂O = 2NaOH + H₂...

1) so2+> 3o3 2)fe +cl2 --> fecl3 3)zn+hcl --> zncl2+h2 4)2mg+o2=mgo 5)3na+h2o = 3naoh + h2
