Magnesium laboratory

Purpose: To determine the empirical formula of an oxide of magnesium (mg) Materials:

* Crucible

5. Crucible Cover

* Crucible tongs

2. Triangle pipe stem

5. Ceramic Plate

* Diamond ring stand

2. Steel constructed from wool

* Flat iron ring

* Bunsen burner

* Flint igniter

5. Electronic stability

* 25cm length of Magnesium (mg) ribbon

Treatment:

Safely and securely setup your ring stand, ring, and triangle tube stem. Making use of the crucible tongs put the crucible onto the triangle pipe stem. Make certain that the cover is estropear, leaving a tiny opening. High temperature the crucible using a excessive flame for about 5 minutes to push out virtually any impurities they may be in the crucible. Allow to cool to get 10 minutes. Making use of the tongs, place the crucible and cover on a dietary fiber pad and record the mass with the crucible and cover while using scale. Record your data. Clean a 25cm long ribbon of magnesium (mg) with a ball of metallic wool. Coil up the bow of magnesium so that it will easily go with the crucible. Record the mass with the crucible, cover, and magnesium. Place the crucible with the substance in this on top of the triangle water pipe stem. Place the cover apocar to allow the flow of oxygen in the crucible. Temperature it carefully for 2 minutes, after that under high heat, heat it up for another a couple of minutes. Allow to cool intended for 10 minutes. Put the crucible, cover, and items onto a fiber mat. Record the mass. Replicate 11-16. In the event the difference among mass measurements in less than zero. 01g. record the mass as the mass. In the event the mass is definitely greater than zero. 01g, replicate steps 11-16 until the measurements differ by simply 0. 01g or fewer. Record this kind of in your info table since the constant mass. Put the continues to be of the substance into a unsafe waste pot.

Calculations:

Mass of MG reacted| 0. 43g.

Skin moles of MG reacted| 0. 017g/mol

Mass of product| 0. 67g.

Mass of oxygen reacted| 0. 24g.

Moles of oxygen...
