In carbon dioxide(co2),there are two oxygen atoms for each carbom atom. each oxygen atom forms a double bond with carbon, so the molecule is formed by two double bonds. two double bonds means that the total number of electrons being shared in the molecule is ?

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

Ithink it's the third answer
