Zinc metal can be obtained from zinc oxide (ZnO) by reacting the oxide with the element carbon. The products of the reaction are Zn and CO2. What mass of zinc oxide is needed to react completely with 2.28 mol of carbon?

the answer is true. hope it .

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.
