For items 21 -24, your answer will be the sum of all the numerical coefficients of the reactants and products (use H' instead of H3O') Ex. 2AO + H*-→ 2 H2O +3B2 Answer 2 +1 + 2 +3 =8 21. Cr20,2 + CI => Cr3+ + Cl2 (Acidic) Question 22 22. Cr20,2- + CI → Cr + Cl2 (Basic) 23. CN+ AsO4 → AsO2 + CNO (Basic) Question 24 24. H2O2 + KMNO4 + H2SO4 → K2SO4 + MNSO4 + H20 + 02 (Hint: Make the total number of electrons lost and gained equal by writing appropriate coefficients for both reducing and oxidizing agents. Then, balance the rest of the equation by inspection)
