Abstract: <Tab/>The purpose of this lab was to test the law of definite proportions for the synthesis reaction of combusting magnesium. In this lab, the polished magnesium ribbon was placed in covered crucible and was heated in order for it to react with Oxygen presented in air and in water provided. The result showed that Magnesium oxide formed through chemical reaction was made up of 60.19% magnesium and 39.81% oxygen, which is …

…Since no science activity is perfectly done there were few errors that occurred during our investigation. First of all, we had to start off with a smaller burner and we had our reaction going slower than other groups. This caused us to run out of time for further steps of experiment. As a result we didn't give much time for last content to cool down, which is mainly the reason of our not exact results.
