2HCl + Ba(OH)2 -> 2H2O + BaCl2 Based on the above equation, calculate the concentration (in M) of a 49.1 ml solution of Ba(OH)2 if 50.0 mL of 2.95 M HCl is required to react completely. (ans: 1.50 M)

In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater than 100°c the water must be permitted to evaporate quickly the system must be sealed and become pressurized above atmospheric pressure the vapor pressure must be kept below 760 mm(hg)
