What would be the effect upon the calculated GEW of the unknown metal relative to its true GEW if the reagent sulfur contained an inert, nonvolatile impurity

An observation that requires measurement is called quantitative observable or qualitative

The characteristics 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 an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.

What three things does a balanced equation show you?
