Think about the lab procedure you just read. Label each factor below V for variable or C for constant. The amount of sugar in the solution, wether the sugar is stirred. The temperature of the solution, the type of solute added, the type of solvent used

i believe the answer is three water molecules

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.
