One day, you go gold mining and get gold ore. You then purify your compound. According to the math, you should have gotten a theoretical
yield of 45.22 g Au. In fact, you experimentally get 52.91 g Au. What is the
experimental yield that you obtained? *
52.91%
85.47%
100%
117.0%

answer: lol

explanation:

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.
