10. Consider the battery below containing 1M CuSO4 and 1MZnSO4 which is capable delivering a voltage of 1.104 V. You need this voltage to operate your device. Eventually the battery will stop functioning as the voltage will drops to near zero. What can you do to extend the lifetime of the battery. Copper (cathode) 1 Cule 2 Na Voltmeter 0.76 V Sat bodge Cu²+2 Cu(s) +0.34 V Cu Zn(a) $0,2 Zn²+ 2n a. Modify your device to operate at a lower voltage. b. Increase the concentration of CuSO4 in the electrolyte. c. Increase the size of the Zn anode. Zine (anode) Zn(s) 2²2 +0.76 V Zn²+ Cu(a)
