Methods of Analysis Test #1: Polarity, or Effect of a charged rod on a stream of liquid: This test was used to determine the relative polarity of the unknown liquid. The liquid was allowed to run out of a buret and a charged rod was brought up next to the stream. The observations were reported as to whether or not the stream of liquid responded to the charged rod and to what degree. Try this at home with water and a plastic spoon. Rub the plastic spoon against a sweater and move it close to a small stream of water running out of your faucet! Test #2: Volatility, or Rate of Evaporation: A thermometer probe was wrapped with a strip of filter paper. This assembly was soaked in one of the liquids for one minute. The probe was removed, and the temperature change was monitored as the liquid evaporated. The results are given in Graph 1 below. (See Graph)   Graph 1: The curves generated of the change in temperature over time for the substances acetone, hydrogen monoxide, ethylene glycol,…

Please help me with number eight I don't understand it. Please note I am 60 years old trying to help my son learn chemistry and this is not a test.

I need accurate answers with full details. This is my only chance to submit the answers so solve carefully please.

Please complete the following question. If possible, type your work out but do not use images. Also, please just use knowledge at the high school level so that I may understand it. 1

Please answer questions as they are calculated together but just a heads up they are different questions. Thank you for helping me

Charcoal is a good absorbing agent due to its large surface area that can attract particles to its surface True, charcoal can attract particles that can pass through its pores True, the surface area of the charcoal makes it more exposed to the material to be absorbed False, charcoal does not have a large surface area False, the particles cannot be absorbed but will only stick to the surface of the charcoal

Dont give handwritten answers

I need answers for # 2-9 on this worksheet

in the images attach can you please calculate the Concentration of Allura Red M and can you also please please Create graphs with Excel (or a similar program). Plot absorbance (v-axis) vs. A (×- axis) for the absorbance curve determined in part 2. Connect the points with a smooth curve. Plot absorbance (y-axis) vs. concentration (x-axis) for the Beer's Law data from part 3. Draw a best-fit line or use a program such as Excel and do a least-squares fit to determine the best-fit line through the points. lastly can you please show a sample the concentration of the solutions made by dilution. Also use the slope of the best-fit line from your absorbance vs. concentration plot to calculate the concentration of Allura Red in each unknown. Also please dont forget to do the results box in the image attach please please answer super super fast i really need it its very urgent and important please answer everything i need it before the end of today before 11:59pm I would really appreciate it if…
