The Empirical Formula of Magnesium Oxide
Experimental Design
Focus Question
What is the empirical formula for magnesium oxide?
Hypothesis
The combustion of magnesium will generate data which can be used to calculate the empirical formula of magnesium oxide.
Theory
The following combination reaction was used in this experiment:
Magnesium + Oxygen Magnesium Oxide
The Law of Conservation of Mass can be used to determine the amount of oxygen which has reacted with a given amount of magnesium in order to produce a measured amount of magnesium oxide. These masses can then be converted into moles in order to determine the simplest molar ratio and thus the empirical formula for magnesium oxide.
Variables
Variables identified
Type of variable
Treatment
Amount of magnesium used
Independent variable
Different groups will use different masses. Masses will be small enough to ensure that the reaction can occur without requiring the lid to be lifted too often.
Mass of magnesium oxide
Dependent Variable
The mass of this product will be measured after it has been observed that no further reaction will occur.
