If you put water on the pennies you are using with water, the chemical reaction between distilled white vinegar and the pennies stops. The distilled white vinegar that is left on the dry pennies advances the chemical reaction between the copper oxide and the oxygen in the air. The makes the pennies turn a kind of turquoise color copper oxide (verdigris). This is found on the copper (basically the same relationship as tarnish on silver). This also occurs naturally and it can make minerals such as malachite and

Trends in the Mass of a Penny Abstract: Before the year 1982, pennies were made up of a majority of Cu. However, after that year, the composition of pennies changed to a majority of Zn. Our graph of the masses of ten pennies and the year they were minted in showed a trend in the masses of pennies before the year 1982 and after 1982. In order to find out what caused this change, we used the density of the pennies. Density is an intensive property of a system which means it is “a physical property…

Research Paper On Atoms

Atoms are made of protons, electrons, and neutrons. Protons and neutrons are located inside the nucleus that is at the center of an atom. Electrons occupy orbitals, which are located outside the nucleus. In this module, you will study the structure of atoms. Atoms are the building blocks of matter. Every living and non-living thing is made of atoms. Those same atoms make up elements. For example, gold is an element and is made of gold atoms. Atoms are the basic building blocks of matter that make…
