Answer 1

Привет!

1) 3H2SO4+Fe2O3=Fe2(SO4)3+3H2O

2) 3KOH+H3PO4=K3PO4 + 3H2O

3) BaO+H2O=Ba(OH)2

4) SiO2+2H2O=H4SiO4

5) Cr(OH)2=CrO+H2O

Answer 2

Ответ:

1) 3H2SO4+Fe2O3-->Fe2(SO4)3+3H2O

2) 3KOH+H3PO4-->K3PO4 + 3H2O

3) BaO+H2O-->Ba(OH)2

4) SiO2+H2O-->H2SiO3

5) 2Cr(OH)2--t-->Cr₂O₃+2H2O

Объяснение:

Answer 3

1. H2SO4 + Fe2O3 = Fe2(SO4)3 + H2O

2. KOH + H3PO4 = K3PO4 + H2O

3. BaO + H2O = Ba(OH)2

4. SiO2 + H2O = H2SiO3

5. Cr(OH)2 doesn't have an equal sign, so it's not an equation. If you meant to ask for the reaction where Cr(OH)2 is the reactant, the equation would depend on the reaction conditions and the other reactants involved.
