Magnesium lab

Materials

• Bunsen Burner
• Cruicble
• Ring stand
• Tongs
• Striker
• Scale
• 1g magnesium Ribbon
• various size of batteries
• Distilled water
• light strip
• wire strippers

Procedure

• zero the scale and weigh the crucible
• attach the bunsen burner to the gas nozzle
• Find and weight magnesium ribbon
• place the ribbon in the crucible
• turn the gas on light the bunsen burner
• adjust the heat so the tip barley touches the the bottom of the crucible
• let it heat for 2 1/2 minutes or so
• use the tongs to pull out the ribbon do not look at the ribbon!!!! then place it back in
• wait for the magnesium to burn out
• weigh the crucible then compare it with the beginning weight and the weight of the ribbon
• add distilled water to the magnesium then stir
• take the other ends and hook them to various sizes or batteries to see if a light turns on
• when cleaning out crucible dumb mixture in trash and wipe out with a paper towel

Results

I noticed that the crucible was the same weight after igniting and before igniting the magnesium. a faint red light would come on in the light strip while in the mixture with the 2 batteries.

Errors

I didnt notice any errors.

Analysis

• Mg=.4 Mg after=.4 increase=0
• the energy given off was kinetic energy cause of the the light and the heat given off during the reaction
• due to the bright light given off during the reaction magnesium reacts with air
• Mgo, Mg3N2
• because of the light and energy Mgo and Mg3N2 are mainly made up of nitrogen and oxygen
• its a ionic b0nd cause 1 metal and 1 nonmetal that form together
• if a loss in mass occurred then there was probably left over magnesium in the crucible
• magnesium supports a healthy immune system, strong bones, muscle development, and nerve development
• magnesium is commonly used for heartburn to calm stomachs, often used in the form of magnesium hyrdroxide
