The following data was collected when a reaction was performed experimentally in the laboratory. Determine the ammount of NaNO3 that was produced during the experiment. Explain how you determined this ammount.​

since electrons are negative the answer is neagtaive

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.
