Starting with a 2.38 M HCl stock solution, three new standard solutions are prepared by sequentially diluting 15.0 mL of each solution to 250. mL. What is the concentration of the 3rd new standard solution?

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

Don’t know. don’t care.look it up on google

The answer is b. because when it leaves the bat, its bringing motion on where its going.
