Calculate the number of moles of c2h6 in 6.29×1023 molecules of c2h6.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

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

What are the choices?
