Although Ionic Compounds are described by small whole # ratios like MgCl2 combining in a 1:2 ratio, in reality the ions typically combine in much larger ratios like a : ratio

Question 3(multiple choice worth 4 points) (04.04 lc) what does it mean when an element is reduced? it empties a valance shell, reducing its atomic radius. it gains electrons, reducing its overall charge. it increases electronegativity, reducing its ability to bond. it loses electrons, reducing its electron number.

Concentrations expressed as a percent by mass are useful when the solute is a a. liquid b. gas c. solid
