The actual mass of icon(III) chloride (FeCla) produced was 24.3 g
Calculate the percentage yield
(If you did not answer part (b0) assume that the maximum theoretical mass of
iron(ill) chloride (FeCl3) is 28.0 g. This is not the correct answer to part (b)(i).)

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
