Ajar test has shown that the optimum dose of ferric chloride consumes all of the alkalinity. if the amount of ferric chloride that is in excess is 10 mg/l, how much lime (ca(oh) 2 ), in mg/l must be added to neutralize the acid formed?

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.

The atom fluorine generally will become stable through the formation of an ionic chemical compound by accepting electron(s) from another atom. this process will fill its outer energy level of electrons.
