to contribute systematic error to the data and results, point this out in sufficient detail in this section. Check with your demonstrator, tutor or lecturer if you are unsure about how to determine uncertainties or whether error bars are required for your experiment. Environmental Ecology Journal 75, 23-29. The discussion section is where you: comment on the results you obtained interpret what the results mean explain any results which are unexpected. Graduated cylinder, with rubber stopper was filled with an amount of water. The results also had large standard deviations, possibly due to these physical constraints or human error in weighing leaves. In addition to defining acids and bases, Bronsted-Lowry further classified acids and bases as being either strong or weak.

The aim of this experiment was to identify decomposition rates of leaf breakdown to establish rates of energy transfer. Through this lab, we will be investigating one factor that will affect the equilibrium constant. Data can be presented in other formats, such as images: Calculations When showing calculations, it is usual to show the general equation, and one worked example. Some chemical reactions are reversible, and when the rate of the forward reaction equals the rate of the reverse reaction, the process has reached equilibrium. These need to be labelled appropriately to clearly indicate what is shown. Results: The results for reaction time of the different metals, to show which is the most reactive in acids. Length: 344 words (1 double-spaced pages rating: Excellent, essay Preview. Variables: Independent: Aluminum foil, Copper coin, lead pellets, Zinc from a battery, Magnesium from Antacid, and Iron Shavings. It has been formatted in accordance with the csiro referencing style. Data are often presented in graphs, figures or tables. This may have negatively affected the accuracy of the results by reducing the differences in habitat at these sites, as seen in other experiments (Jones. Typically these will be included in the introduction to establish evidence of background for current theories or topics.
