Insert the values from the question above for x, y, z, & n into kxfey(c204)z nh20 anod provide the correct coefficients to balance the following equation fe(nh4 )2(so4 )2.6h20+_h2c204+_k2c204+-h202 → k, fey c204)z nh20+(nh4)2so4+ h2s04+h20 (hint: remember h202, an oxidizing agent, was used in the synthesis, so you'll need to do a redox balance. start with just the iron ions, balance the reaction, and then add the full formulas.)

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
