Conclusion 1) One error could be if the Magnesium did not heat all the way, then there were still solid pieces of Magnesium that could have made the mass greater. Extra mass in the crucible could cause the oxygen to be too low because extra mass would consume more space and would lessen the amount of space for oxygen within the crucible. 2) a. If you put more water in to the crucible than is needed for reaction 3, and did not wait for the excess water to dry out, then there would be to little oxygen. This is because the product in the crucible and the water would increase the amount of weight of the crucible/product as a whole and would leave little space for oxygen.

Unit I: The Concept of Life Biology : The Study of Life How is Life Defined? Key Idea: All living things carry out eight essential life functions. Collectively, the eight life functions are known as metabolism. Nutrition: the process in which food (organic molecules) is absorbed (ingestion) and used or broken down (digestion). Transport: the process in which material is moved from one place to another (circulated) within organisms. Active Transport: the type of transport that moves material from a low to high concentration while using energy.
