OneClass: balance the following equation...

12) 2Al2O3 4Al + 3O2↑ (электролиз раствора Al2O3 в расплаве криолита).2 K2CrO4+10 HCl+3 Na2SO3→3 Na2SO4+4 KCl+2 CrCl3+5 H2O. This is an oxidation-reduction (redox) reaction Na2SO3 is a reducing agent, K2CrO4 is an oxidizing agent.Oxidation of formic acid with K2CrO4 produces carbonic acid (HO COOH), but this molecule is very unstable, it tends to decompose in CO2 and H2O. What is the chemical reaction between hcl and k2cro4? balanced equation: 2HCl + K2CrO4 ---> H2CrO4 + 2KCl.K2CrO4+Na2SO3+HCl--->KCl + Na2SO4+CrCl3+H2O. KCl(s) → K+(aq) + Cl‾ (aq) Solid KCl dissolves as shown in the above equation. A 6.60 g sample of KCl was dissolved in 42.3 g of water.
