A compound is 43.7% phosphorus and 56.3% oxygen. The formula mass of this compound is 284g. Calculate the empirical formula and molecular formula of the compound.

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

The water cycle increase the water content in the earth atmosphere
