Well, 1/2 h2 as a gas, temperature, at one bar, plus 1/2 bromine, no actually bromine is a liquid at room temperature and one atmosphere they form hbr which is a gas at room temperature and one bar, right. Notes on oxidation numbers, complete 1202 and go over, (acidic example) and (if time) discuss why – batteries and salt bridge example.
Chapter 6: thermochemistry 168 620 strategy: the work done in gas expansion is equal to the product of the external, opposing pressure and the change in volume w = −pδv we assume that the volume of liquid water is zero compared to that of steam.
