Using Table 1.1, but without using your calculator, decide which has the larger mass: 20. mL butane or 20. mL bromobenzene 10. mL benzene or 1.0 mL gold 0.732 mL copper or 0.732 mL lead
For the data below, if a diluted (DF=100) water sample has an absorbance of 0.057, calculate the number of Cu atoms in a 100 mL sample. Answer using 3 significant figures. For Scientific Notation use this pattern example 6.02x10^23 Cu mg/L Absorbance 0 0.002 2 0.045 4 0.093 6 0.133 8 0.177 0.197 10
To run a spectrophotometry experiment, begin by warming up the spectrophotometer and preparing the samples. Be sure to select the correct absorbance (X), then run a measurement on the sample solution. Follow up by running measurements on sample solutions. Once data is collected, turn off the instrument, clean the area, and discard the samples. Partially correct (2 of 4 correct)

It occurs when gases such as nitrogen (N₂) come out of solution in the blood. This can lead to symptoms including joint pain, shortness of breath, and paralysis. Severe cases may result in death. a What type of molecule (ionic, polar covalent, nonpolar covalent) is nitrogen gas? b The liquid medium of blood is water. What type of compound (ionic, polar covalent, nonpolar covalent) is water? c What happens when molecules such as nitrogen gas mix with water? How does this explain the problems we see with decompression sickness?
I only need help on the third problem. The second problem that is already answered is needed to solve the third problem. This is the formula I need to follow for the third question. D? = ??? + ( ??? − ??? ) divided by 3 Where TBM is the total body mass and LBM is the lean body mass. Do not let all these letters confuse you. Just remember DM is the dosing mass so this will end up being a number to put in another formula below. LBM is a number you would find out from a patient you might be about to give Heparin. And TBM is the same. We use these letters to remind us what those quantities represent. 2. If the patient is less than 70 years old, the loading dose is 80 Howell Units2 per kilogram of DM. One Howell Unit is equivalent to 0.0020 mg of pure heparin. Calculate how many mg of pure heparin is in 80 Howell Units. Do not worry about the kilograms of DM yet. Answer: 0.16mg heparin/1kg You need this to answer the third question. Which I do not get. I was told to convert 40…
Please confirm if my answer is correct or not. Due to the need for this to be correct I would like you to provide me with a confidence score in you answer on a scale from 1 to 10 how confident are you in your answer. Please be sure to double check your answer
2. What measurements might you record regarding water samples to assist with the quantification process? How might these measurements have error introduced? 3. Create a table of your observations made during the experiment. For example: Sample 2 Sample 1 Initial After shaking Write a brief summary of any conclusion that were reached. 4. With your group, write a sentence statement of the objective of the experiment and the method that will be used.
Make a dilution series to get to 1:100. Start with making 1:10 dilution by adding 1mL of sample and 9mL of diluent, now continue the series to get to 1:100. The formula you may use is V1D1=V2D2
1. You are working with a colleague to measure the carbonate chemistry of a set of water samples. Unfortunately your colleague is a bit sloppy, and when you look at the data, you realize there must have been some errors in the measurements. Blank cells in the table below mean your colleague didn't collect data for that species in that sample. For each sample (#1-6), EITHER explain why at least some measurements for that sample must be in error OR fill in the missing data with reasonable values. (Note: you can assume the precision of the measurements is ±1mM, so inconsistencies below that level do not necessarily indicate errors.)

Current Attempt in Progress From the curves shown in Animated Figure and using the following Equation, determine the rate of recrystallization for pure copper at the several temperatures. Make a plot of In(rate) versus the reciprocal of temperature (in K-1). (a) Determine the activation energy for this recrystallization process. (See Section FACTORS THAT INFLUENCE DIFFUSION.) (b) By extrapolation, estimate the length of time required for 50% recrystallization at room temperature, 20°C (293 K). (a) i kJ/mol (b) i days
