The chemical equation shows the combustion of methane gas:
CH4(g) + 202(g) → CO2(g) + 2H2O(g) He = -890 kJ/mol

How much heat would be released if two moles of CH4 are
combusted?

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
