Find the AH° for the reaction of two moles of aqueous ammonium hydroxide and one mole of aqueous calcium chloride that produces two moles of aqueous ammonium
chloride and one mole of solid calcium hydroxide. (Hint: Be careful looking up the AH
for ammonium chloride and calcium hydroxide.)
2NH, OH(aq) + CaCl(aq) 2NH, Cl(aq) + Ca(OH)(s)

The density would be 1.622

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

Ibelieve the answer is b.2200 watts, because p=vi; p=220(10); then p=2200hope my answer has you : )
