explain why when acidified solution of ethanedioate is titrated with a solution of acidified potassium manganate (vii) ,the colour of the manganate disappears slowly at first and then rapidly as the end point is approached

Ethene molecular fórmula= c2h4molecular weight = 29.046g/molhope it : )

What do you mean by that? like the contents? the thc level?

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

Hey : )a transition from the first energy level to the fourth energy level
