A chemist designs a galvanic cell that uses these two half-reactions: half-reaction standard reduction potential
Cl2(g) + 2e- → 2Cl- E0red = +1.359 V
MnO2(s) + 4H+ (aq) + 2e- → Mn2+(aq) + 2H2O(I) E0red = +1.23 V
a. Write a balanced equation for the half-reaction that happens at the cathode.
b. Write a balanced equation for the half-reaction that happens at the anode.
c. Write a balanced equation for the overall reaction that powers the cell.
Do you have enough information to calculate the cell voltage under standard conditions?

What will most likely happen when two bromine atoms bond together?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

The following questions a24 - a26 relate to 100 ml of 0.0150 m solution of benzoic acid (c6h3cooh). ka(c6h3cooh) = 6.4 x 10^-5. what is the ph of the solution after the addition of 1 x 10^-3 moles of naoh? you may assume no volume change to the solution upon addition of the naoh.
