We mixed Aluminum Sulfate with Barium Nitrate in two test tubes. The Barium Nitrate is a clear liquid that had no smell. The Aluminum Sulfate also was a clear liquid with no scent. When mixed, the center of the liquid turned into a milky white precipitate.
After 2 minutes the white substance sank to the bottom while the clear liquid sat on top.

First we felt the material of a piece of Magnesium. It felt maliable and smooth. We also worked with a Bunsen burner, spark lighter, and tongs. One person in our group turned on the bunsen burner, while the other took the Magnesium and held it over the fire. After a few seconds the magnesium began to react …show more content…
Calcium looks like a gray, rock like substance, and hydrochloric acid looks like a clear liquid with no significant odor to it. We put Calcium into a tube and add a squirt of acid. When they are in contact of each other, the product begins to bubble up. We then place another tube over it, in order to fill it with the gas being produced. Then we place a fire underneath the gas filled tube. When they are exposed to each other the gas catches on fire and it makes a loud popping noise and a flash. …show more content…
Explain this using the information in the chemical equation. The magnesium did not leave a significant odor because it is a pure metal, and pure metals are known for not leaving a distinguished scent when burned. 2MgO also tells us that oxygen is also the final reactant in reaction #2, and we know that oxygen does not leave a significant odor like other gases. So when Magnesium and Oxygen combine, it is highly probable that they would not leave a significant odor like other reactants.
3.What is the name of the gas that was collected in Reaction #3? Back up your answer based on what you know about the identity of that gas and its well-known chemical properties. The gas we got was hydrogen. Hydrogen is a chemical element with the atomic number 1, and has the chemical symbol of H. It is known to be very flammable, and it is also used as a fuel source for a space shuttle’s main engine. So when the fire lit inside the tube, the hydrogen reacted and created a flame strong enough to produce a loud sound and a flash.
4.Although this is highly unadvisable, any liquid inside of a bottle of hydrogen peroxide can be swallowed as long as the bottle is very, very old. Explain this based on the chemical
