Where do the oh- ions go as additional acid is added? 1. they evaporate. 2. they combine with excess h+ ions to form more water. 3. they remain in solution at the same concentration. 4. they remain in solution but change concentration.,

The result when the OH- ions go as additional acid is added is that they remain in solution but change concentration. This is because  when you add more acid to hydroxide, it will change its concentration due to the acidity added.

I’m not sure what your trying to say here.. can you clarify again?

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
