A1.000 g sample of a metal chloride, mcl2, is dissolved in water and treated with excess aqueous silver nitrate. the silver chloride that formed weighed 1.286g. calculate the atomic mass of m.

Given 1 gm of MCl2 fors 1.286g of AgClmolar mass of AgCl is 143.5 g 1.286g of AgCl contains 1.286/143.5 mols of AgCl =0.0089616 molseach mol of MCl2 release two Cl- ionshence number of mols MCl2 given(1gm) is 0.0089616 /2=0.0044808 mols hnce one mol of MCl2 weighs 1/0.0044808= 223.17g

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
