Calcium carbonate is a naturally occuring white solid in the manufacture of lime and cement. calculate the number of Ib moles of calcium carbonate in: a) 50 g-mole of CaCO3
b) 150kg of CaCO3
c) 100 Ib of CaCO3

i think is conclusions.i think so

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.
