Let's say that group A runs an experiment to calculate density of an object and gets a value of 10 g/cm^3 with an error of .005 g/cm^3. Lets say another group (B) uses a different experimental technique to measure the density of the same object and finds a value of 8.2 g/cm^3. Did group A do a better job than group B? Make sure your answer includes how random and systematic error played a role.

Let's say that we have a layer of air with an initial temperature of 0°C and a depth of 310 m. This parcel then flows over an expanse with a temperature of -3°C. If the initial dewpoint of the air is -1°C, how far across the ground must the air travel before advection fog first forms. Please give your answer in kilometers!!! You can assume smooth ground with a roughness of 0.002 m. Please tell me the following: What equation(s)...

Let's say there is a retainer wall that typically holds back water. However, there has been an oil spill and we need to calculate the force this new fluid has the wall to determine its capacity. As shown in the diagram, there is 3ft of oil sitting on top of 17ft of water. Oil has a density of 55lbf/ft? and water has a density of 62.4 Ibf/ft?. You can assume the top of the fluid surface is open to the...

How do you calculate the theoretical yield for luminol from
3-nitrophthalic acid?
Let's say we start with 2.5 grams of 3-nitrophthalic acid.
NO, O 2 2 a.) NaOH/H2O, Na2S2 220 C, 3-4 min 100 'C, 5 min NH NH b.) CH3COOH (Triethylene glycol # solvent) 3-nitrophthalic acid (Does NOT chemiluminesce.) 3-nitrophthalhydrazide Does NOT chemiluminesce.) 2 NH Luminol (Does chemiluminesce.) Figure 11.1

Can I add error bars for one measurement? let's say that we have energy value for each temperature degree, and when plotting the energy vs. temperature, we get a scatter plot. Can we add error bars to the point in this plot? or does the experiment has to be repeated in order to get multiple trials. In other words, Standard deviation and standard error are used in calculation and generating error bars. How these quantities are calculated if I only...
