A40-lb container of peat moss measures 14 * 20 * 30 in. a 40-lb container of topsoil has a volume of 1.9 gal. (a) calcu-late the average densities of peat moss and topsoil in units of g> cm3. would

i'm pretty sure it is letter c.) car

c. orbital shape i hope this is correct

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.
