In the following reaction being researched as an alternative to standard forms of combustion, ammonia is combusted to produce nitrogen monoxide: NH3 + O2 --> NO + H2O If I start with 20 moles of ammonia and 20 moles or oxygen, which of these reactants limits the production of NO? Also, can you figure out how much of the excess reagent is left over?

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 answer is 4 i don't know if its right let me see.
