Using the ion-electron (half reaction) method, balance the following two redox reactions in the indicated pH. I) Zn(s) + NO3ˉ(aq)  —–>  Zn2+(aq)  +  N2(g)   [Acidic media] What was the stoichiometric coefficient for Zn2+(aq) and how many molecules of water are in the final balanced reaction? [a] II) SO32ˉ(aq) + Cl2(g)  ——>  SO42ˉ(aq)  +  Clˉ(aq)  [basic media]   What was the stoichiometric coefficient for SO32ˉ(aq) and how many mol of hydroxide ions are in the final balanced reaction? [b]

When your blood pressure drops, baroreceptors in the blood vessel walls detect decreased amounts of stretching. When this occurs, the vasomotor center in the medulla oblongata has the sympathetic nervous system increase its activity, leading to vasoconstriction of the blood vessels and increased blood pressure. In this example, which structure is the effector?

For the following equilibrium, answer the two questions below: (4 pts) HPO42ˉ(aq)  +  H2O(l)  —->  H2PO4ˉ(aq)  +  OHˉ(aq) If KH2PO4 is added to this equilibrium, in which direction will the equilibrium shift? Will the final concentration of OHˉ increase or decrease?
