H2so4(aq) 2h+(aq) + so4 2- (aq) , the addition of which compound will cause a shift in equilibrium because of a common ion effect?

THe addition  of  strong  electrolyte    such  as MgSO4 compound   will   led the  equilibrium   to   shift  due  to   common  ion  effect. The  addition   of  common  ion   decrease  the   solubility  as  the  reaction  shift  to  the  left  thus  less  product  is   formed.  

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

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.
