How much heat is released when 80 grams of NaOh (molar mass= 40 g) dissolve in water?

How many grams of glucose C6H12O6 (molar mass= 180g) must be burned to produce 180.4 KJ?

How much heat is absorbed in the formation of 1.00 mole of HI (g) from H2 (g) and I2 (g)?

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
