I. Purpose:
* To determine the chemic formula of milligram oxide.
* To compare properties of elements and compounds.
* To articulate the inquiry on the chemical formula of magnesium oxide using the formal laboratory report format.
II. Problem:
* Synthesizing a magnesium oxide compound.
* Determine hole of each element in the sample.
* Determine frame of moles of each element present in the sample using withdraw atomic weights.
* Expressing the smallest whole number mole ratio of the elements present.
* astute the compounds formula as a whole.
III. Hypothesis:
Is it physically potential to synthesize magnesium oxide compound to determine the mass and number of moles of each element in the sample in range to calculate the compounds formula as a whole?
IV. Materials, Methods and Procedures:
Materials:
* bunsen burner Burner
* Ring and Ring Stand
* Crucible tongs
* Crucible and lid
* Clay trigon
* Scissors
* emery paper
* Magnesium ribbon
* Weighing balance
Methods and Procedures:
1. Fasten a ring to a ring stand and place a clay trilateral in the ring.
Place the crucible in the clay triangle and position the cover on the crucible such that a small gap is left open. awaken until the crucibles bottom is blushful hot. Allow them to cool to room temperature, weigh the crucible to +- 0.001 g and lid together, and record the mass. Always handle the crucible and lid with crucible tongs, and us the same balance for all deliberations in this experiment. See figure below.
2. Obtain to the highest degree 30 cm (12 in) of magnesium ribbon. Polish it with sandpaper and rescind the ribbon into a spiral that will fit in the bottom of the crucible. Examine its properties and record in the table.
3. Put the magnesium spiral in the crucible and reweigh the crucible and cover to +- 0.001 g.
4. Heat the crucible gently with a Bunsen burner for about 5...If you fatality to get a full essay, order it on our website: Orderessay
