A student is trying to calculate the density of an ice cream cone. She already knows the mass, but she needs to determine the volume as well. Which of the following formulas can be used to calculate the volume of the cone?
OVE
Tr
0 v= 1 / 1
Ov=s
V = Tiran

1.solid

2.carbon dioxide

3.helium

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.
