ethanal
I think the reaction equation can be written as follows: K2Cr2O7 (aq) + BaCl2(aq) ------ BaCr2O7(s) + 2KCl(aq).
Cl2 + 2KI --> 2KCl + I2
ethanol is converted into acetic acid....
Cr2O72- + 6Fe2++ 14H+ --> 2Cr3+ + 6Fe3+ + 7H2O
ethanal
K2Cr2O7 + Na2C2O4 --> K2C2O4 + Na2Cr2O7
potassium
F+ 2KCl -> F2KCl
I think the reaction equation can be written as follows: K2Cr2O7 (aq) + BaCl2(aq) ------ BaCr2O7(s) + 2KCl(aq).
2KI + F2 ----> 2KF + I2
Cl2 + 2KI --> 2KCl + I2
6 FeSO4 + K2Cr2O7 + 7 H2SO4 = 3 Fe2(SO4)3 + K2SO4 + Cr2(SO4)3 + 7 H2O
ethanol is converted into acetic acid....
Cr2O72- + 6Fe2++ 14H+ --> 2Cr3+ + 6Fe3+ + 7H2O
2KBr + 2H2O----->2KOH + Br2 + H2(g) this is the reaction in electrolysis of KBr in aqueous solution
The BaSO4 (barium sulfate) will precipitate out of solution because it is insoluble, whereas the KCl2 is soluble and will remain dissolved. The balanced equation is: K2SO4 + BaCl2 -----> 2KCl + BaSO4
