A) a barium hydroxide solution is prepared by dissolving 1.34 g of ba(oh)2 in water to make 61.1 ml of solution. what is the concentration of the solution in units of molarity?
b) if 15.1 ml of the barium hydroxide solution was needed to neutralize a 5.92 ml aliquot of the perchloric acid solution, what is the concentration of the acid?

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

Where is the illustration?

Remember that rust prevented by placing a sacrificial electrode in electrical contact with the iron. the sacrificial electrode must be composed of a metal that  oxidizes  more easily than iron (that is, it must be below iron in table 18.1).
