Question

Химия: Na+hoh-- na2o+hoh-- naoh+hcl-- naoh+cuso4-- naoh+co2-- hg(no3)2+cu-- cu+feso4--

ЕвгенийМатвеев · Answer

2Na+ 2H2O =2 NaOH + H2Na2O + H2O = 2NaOHNaOH + HCl = NaCl + H2O2NaOH + CuSO4 = Cu(OH)2 + Na2SO42NaOH + CO2 = Na2CO3 + H2OHg(NO3)2 + Cu = Cu(NO3)2 + HgCu + FeSO4   реакция не идёт...
