we need to calculate the difference of the volume before and after each titre. For example‚ the volume used in the first titre would be calculated by: 25-21.3=3.7 mL Uncertainty: (Uncertainty of the previous volume + uncertainty of volume after titration) = (0.05+0.05) =0.1mL Calculating the rest of the titres in a similar fashion (previous volume-volume after titration) the following table of results is obtained: Table 3: Table of the volume of 0.201moldm-3 sodium hydroxide (NaOH) used

In the express mail industry shipment volume was increasing quickly‚ but prices were falling. For this reason total revenues of the industry had been growing by only 10-15% each year and were expected to grow about 10% for the next five to ten years. The customer base of the industry was broadening due to acceleration in the pace of business. However‚ customers of this industry were not very loyal‚ even though discounts based on volume did encourage customers to focus on one carrier. Customers chose

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Most gas grills made in the USA will cost less than $300‚ and you can use them for three years. If you hope that your grill lasts longer‚ check the design of the grill before buying. Test the sturdiness because the more stable‚ the better. Check the warranty of the burner to discover the type of grill that it will be. For example‚ burners are one of the most replaced parts on a gas grill‚ and if you see a short warranty‚ that could hint that the grill will not last as many years. What else should

Multiple chamber this type of combustion chamber is used on centrifugal engines. It is constructed of chambers positioned radially around the engine; air is directed by ducts into each individual chamber. Every chamber has an inner flame tube where there is an air casing. and the separate flame tubes are all inter connected this allows each tube to operate at the same pressure and allows combustion to spread around the flame tubes during engine start. Annular Chamber This type of combustion
