Question

Химия: Co2+h2so4= hg+h2so4= h2po4+h2so4= mg+h2so4= cr(oh)3+h2so4= kcl+h2so4= li2o+h2so4=

katyabobkova · Answer

co2+h2so4=реакция не идет

hg+2h2so4=SO2 + HgSO4 + 2 H2O

3h2po4+h2so4=2H3PO4+H2SO4

mg+h2so4=MgSO4 + H2↑

cr(oh)3+h2so4=Cr(OH)SO4 + 2H2O

Kcl+h2so4=K2SO4 + 2HCl↑

Li2o+h2so4=Li2SO4+H2O
