H2So4 is a strong acid and a strong electrolyte which means that when this dissociates in water, the dissociation process is complete. The first dissociation is
H2 SO4 = H + HSO4-
This can further release H+ and dissociate SO4- instead already
Gases are less dense and the molecules are farther apart which means that it can be compressed
Double replacement i believe
Whenever energy is converted from one form to another, some of that energy is lost by being changed into heat.
