The Fizzing of Pop Lab
It is a warm summer day, and you reach into the refrigerator to grab a can of pop (soda). You open the can of pop, and it begins to fizzle. The fizzle is due to carbonation. Carbonation occurs when carbon dioxide (CO2) dissolves in water or an aqueous solution. Since carbon dioxide does not easily dissolve into water under normal conditions, companies must increase the pressure in the can and keep the pop at a low temperature. If these conditions are met then carbon dioxide can dissolve into the water in the pop. After the carbon dioxide is dissolved in the water, the pop can is sealed tightly. After the pop can is sealed, some of the carbon dioxide sits on top (between the pop and the lid of the pop can) which is why you hear a fizzle when you open the can of pop. The rest of the carbon dioxide will come out of solution due to the can being opened (less pressure).
Gas Laws Lab
Boyle’s Law, Charles’ Law and Gay-Lussac’s Law show how pressure, volume and temperature change and/or are held constant under a variety of circumstances. Temperature is represented by Celsius (°C) and Kelvin (K) in this simulation, the pressure is given the unit in atm, and the volume uses Liters (L) as its unit. In this lab, you will be able to change the volume, temperature and/or pressure by clicking on the arrows. Using this information, the information learned in 9.1, and the lab (simulation), answer the following questions.
Reaction Rates Lab Report
Chemical Reactions Lab
This lab is broken up into four parts. Parts 1 through 3 will focus on what can happen in a chemical reaction. Part 4 will focus on a real world problem. Make sure to follow the instructions for each part and answer the questions that follow.
The Penny Lab
The forces that hold atoms together within a molecule are called intramolecular forces. Examples of intramolecular forces include ionic bonds, covalent bonds and metallic bonds. Ionic bonds are formed due to the transfer of valence electrons between a metal and nonmetal. Covalent bonds are due to the sharing of valence electrons between two nonmetals. Metallic bonds occur between atoms of metals and produce a sea of electrons. The interaction (force of attraction) between molecules is called intermolecular forces. Intramolecular forces are stronger than intermolecular forces because the attraction that holds molecules together are stronger than the attraction between molecules. In this lab, you will learn more about intermolecular forces.
Acid and Base Lab
Acids and bases are just specific types of solutions. Water is almost always the solvent, and the solute varies depending on what type of acid/base is present. A pH scale measures how acidic or basic a substance is. For this lab, you will determine the pH of different substances. Follow the instructions and answer the questions to the best of your ability.
