Consider a sample of compound contain 1.719c 0.284gh so find emprisical formula

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.
