1. Calculate the theoretical yield percentage of a reaction between sodium and water, if 25.0 g of sodium react with excess water and if 15.5 L of gaseous hydrogen are collected at NTP conditions.
2. Bromine can be obtained from the decomposition of calcium bromide by means of electrolysis. If 10.0 g of calcium bromide are dissolved in water before electrolysis and if 1.75 L of gaseous bromine is produced at 70 °C and 80 kPa, what is the theoretical yield percentage?
CaBr2 à Ca + Br2
