how do i find KWH from WATTs, let's say i have 381.6933966 [w] device, how do I find the cost per KWH if the rate is $.12?
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
How do I use Beer's law to convert all my absorbance data into concentration data in excel (and also by hand)? There are three different temperatures in excel. Let's say 10 Celcius, 20 C and 30. They all have the same concentration of the solution used which was 3.0*10^-5 and the length was 2 cm. How do I do this on excel and then generate a data vs. time graph? I also need to create graphs with Ln (temperatures) and...
Describe, in words, how you would measure saturation pressure as a function of temperature. Let's say, for example, that your boss wants you to measure the saturation pressure of water from 300K to 500K. How would you do it? What equipment would you need?
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.

Question 7 8 point The table below shows the variation of the viscosity of water with temperature. Using linear interpolation, calculate the viscosity for temperatures of 21, 62, and 88°C. Temperature, T (°C) Viscosity, u (Pa*s) 1.75 X 10-3 1.02 X 103 6.51 X 10-4 4.60 X 10-4 3.50 X 104 2.82 X 104 60 80 100 Answer: T = 62 °C u = X 10^ units:
Let's say we want to withdraw $900 per month for 4 months. How much do we put into a savings account today that earns 6% compounded monthly? Assume we will have no money left in the account at the end of the 4 months.
Let's not forget about regression! Let's say I'd like to make a prediction about how quickly my new potato plant will grow. I measured its height everyday and recorded it. Here's the height in cm for the first 12 days .1 .1 .3 .9 1.2 1.4 1.8 2.0 2.2 2.5 2.7 If i want to know how tall my plant will be on the 16th day, I can run a regression on my data get an equation that'll predict it...
