In this lab we will be heating up substances and use them to galvanize pennies. When you heat up the zinc, and then coat the penny in it, it then galvanizes the penny. Meaning, it helps protect the penny from oxygen and water. Afterwards, you will need to record data such as the mass of the penny. This helps keep track of what physical traits are being changed during this experiment. On part B of this experiment, you will be heating up the now galvanized pennies in order to see what reaction you get. The reaction you should receive from heating up the now zinc-covered pennies is that the pennies will change color.

In metallic bonding, the reason it is so good at conducting heat and electricity, is the electrons are loosely held in the atom. Also, the structural pattern of metals is hexagonal-close-packing (Francis, E . . .). Metallic bonds are when the electrons are shared and are able to move and how C models show that. The idea of the electrons being able to move, delocalized electrons, helps produce its characteristics like conductivity and malleability, etc. (Anderson . . .). In a redox reaction, oxidation and reduction happens. Also you can’t have reduction happening without oxidation also happening along with it. Redox reactions oxidation is the loss of electrons
and reduction is the gain of electrons (Redox . . …show more content…

Iron not only needs water, but also oxygen in order to form rust. (Rusting . . .). Galvanizing involves coating corrosive metals with a non-corrosive metal, which not only protects from corrosion of soft metals but also adds strength of the original, uncoated metal. Hot-dipping is one way of galvanizing, which is when you dip a metal into hot melted zinc (What . . .). When the metal is dipped into the melted zinc, it creates a protective shell around the metal and keeps it from rusting away from oxygen and
