What is the formula for co3 2- and al3+ ?

The formula for the given above is obtained by cross multiplying the charges of the given set of atoms. The element with a positive value for the charge should be written first. This may be shown through the formula,
                                     Al2(CO3)2.

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
