Find the number of moles of water that can be formed if you have 210 mol of hydrogen gas and 100 mol of oxygen gas.

200 moles The balanced equation for creating water from hydrogen and oxygen gas is 2H2 + O2 => 2H2O So for every mole of oxygen gas, you need two moles of hydrogen. So looking that the amount of oxygen and hydrogen you have, it's obvious that oxygen is the limiting reactant since 100 moles of oxygen will consume 200 moles of hydrogen. While 210 moles of hydrogen requires 105 moles of oxygen. Now for each mole of oxygen gas you use, you create 2 moles of water. So 100 mol * 2 = 200 mol So you can create 200 moles of water from the given amounts of reactants.

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
