Question

1)SiO2+H3PO4= 2)SO3+KOH= 3)Fe203+HCL=

Answer 1

Ответ:

1)SiO2+H3PO4=SiO2+P2O5+H2

2)SO3+KOH=K2SO4+H2O

3)Fe2(SO3)3+HCl=FeCl3+H2O+SO2

Answer 2

Here are the balanced chemical equations for the reactions you've mentioned:

1. SiO2 + H3PO4 → SiO2 + 2 H2O + P2O5 This reaction produces silicon dioxide, water, and phosphorus pentoxide.

2. SO3 + KOH → K2SO4 + H2O This reaction produces potassium sulfate and water.

3. Fe2O3 + 6 HCl → 2 FeCl3 + 3 H2O This reaction produces iron(III) chloride and water.
