what is the molarity of a solution made by dissolving 2.51 g of sodium carbonate in distilled water and making it up to 100ml with distilled water in a volumetric flask

the answer is true.

this statement is true.

Icant see the pictures 

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
