time range from January 1985 until and including December 1997‚ whereas the last year is not used for constructing the optimal forecast‚ obtained by fitting a model through the data until the end of 1996. This will enable us to forecast the year 1997 using our model‚ and then comparing it to the actual data. Assuming no large one time shock‚ meaning that it is not captured by seasonality or cyclical behaviour in the data‚ occurs in this year‚ a graphical comparison of our forecast and the whole data

Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean

Analysis of a Chemical Mixture Using the Ideal Gas Law The objective of this experiment was to determine the composition of the NaNO2 mixture in the net ionic reaction of NO2-(aq) + HSO3NH2(aq) → HSO4-(aq) + H2O(l) + N2(g) in unknown mixture number nine. It was known that NO2-(aq) and HSO3NH2(aq) were in a stoichiometric 1:1 molar ratio. In trial one the percent mass of NaNO2 in the unknown mixture was 59.30%. In trial two‚ the percent mass of NaNO2 was 63.47%. Lastly in trial three

Created using Notebooks by Droid-Veda LLP Jan-31-2013 The data resulted from the experiment shows how there was difference between the average time read between the control group and the experimental group. the experimental group had a word list with conflicting word stimuli‚ causing the there to be a thought processing allowing the participant to read the color of the word rather than the word itself. The thought processing took more time‚ resulting in the experimental group to take a longer time

Using AVR Timer/Counters: Pulse Width Modulation Modes Two excellent tutorials have already been written about the AVR timer/counters‚ and I want to fully acknowledge this excellent work. The tutorials are by abcminiuser (aka Dean Camera) on the this forum. It’s not my purpose to steal any of Dean’s thunder‚ since I know he plans to explain PWM and has already started that section of his tutorial. It seems to me that PWM is complex enough that it can bear explaining twice‚ and it seems that
