Wtite and balence the equation for formation of so3 from so2 and oxygen gases

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.

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

Answer///precipitate;

Qand k are only the same when the forward rate of the reaction has reached zero.
