Sodium (na) reacts with chlorine gas (cl2) to form sodium chloride (nacl) as shown in the equation 2na+cl--> 2nacl. if 4 moles of sodium react, how many moles of chlorine gas will react?

For every 2 mol of Na 1 mole of cl2 will react
4 mol Na = 2mole cl2

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
