A 5,000kg sample of an impure mineral that contains 45.3% iron pyrite reacts with oxygen. Assume the reaction has a yield of 78.0% because it is incomplete. How many grams of iron (III) oxide are produced?

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.
