Answer the highlighted numbers.     BLANK  (Sterile distilled water) Reference Sugar Solution Sample A Sample B REPLICATE 1 BLUE BLUE PINK PINK REPLICATE 2 BLUE PINK BLUE PINK REPLICATE 3 BLUE PINK PINK PINK INFERENCE NOT CONTAMINATED CONTAMINATED 1 2   1. 2. 3. Which of the two samples is relatively clean of biological impurities? 4. Given the result in limit test as an analyst, what will be the final conclusion to this? Write whether rejected or accepted for each sample.  (see attached photo)

In a chromatography experiment, samples can be separated based on their polarity. If you have a polar solvent and nonpolar chromatography sheet, what conclusion can be drawn from analyzing the results? A. The sample that travels farthest up the sheet is most like the solvent, therefore it must be polar. B. The sample that travels farthest up the sheet is most like the solvent, therefore it must be nonpolar. C. The sample that doesn't travel at all and stays near the origin is most like the sheet, therefore it must be polar.  D. The sample that doesn't travel at all and stays near the origin is most like the solvent, therefore it must be polar.

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Instructions You are required to produce a short lab report using the information given in the accompanying document, ‘Lab report assessment_student data’. This document introduces an experiment, and also provides a set of experimental data for this experiment. You are required to use this data to perform steps 8 and 9 of the procedure. This includes calculations of a particular value, and then comparison to the true value. Consider any experimental errors when comparing calculated values and true values. Your report should be between 300 and 500 words (including all table contents and titles of tables and graphs). Your lab report should consist of three sections only: • Experimental • Results and Discussion • Conclusion You do NOT need to include an introduction section. Your experimental section should be written in appropriate lab report format, (passive voice, 3 rd person, in paragraphs). Your results and discussion section should contain the data presented in table format, and…

What animal can reproduce in large number. Is it Mosquito Frog Butterfly Cat Cockroache Dog

Safety is the     responsibility of the TA only.     primary responsibility of everyone in the lab.     last thing to think about when doing lab experiments.     least important thing, basically just trivia for extra credit.     first topic to read about after you do an experiment.

LAB :DETERMINATION OF ALCOHOL CONCENTRATION IN WINE by distilling 1. How can we know that all the alcohol has distilled away from the wine? Explain. 2. Generate a graph “Temperature vs Volume of Distillate”. Was the temperature constant during distillation ? Explain why it should be so or not so

Procedure 1. A crime situation is presented to you. You need to solve the crime by using your senses and given information. 2. Fill in the investigation report correctly. CRIME SCENE A man is found dead in a vac ant lot near his work place. In the crime scene, the SO cO collected different pieces of evidence including two pieces of cloth tainted with unknown stains. The police are hoping that through these pieces of evidence they could find the culprit criminal. or Cloth A Cloth B Pieces of evidence Data and Result Crime: Date: Piece of collected evidence:_ OBSERVATIONS: Cloth A Cloth B Final Findings: Questions 1. Which of the cloth A and cloth B can be used as possible source of evidence in the crime? Why? 2. Which property of matter did you use in making your observation?

Which of the statements below are TRUE regarding the mean and standard deviation? I.    As the number of measurements increases, x̄ approaches μ if there is no random error.II.    The square of the standard deviation is the average deviation.III.    The mean is the center of the Gaussian distribution.IV.    The standard deviation measures the width of the Gaussian distribution.

Which of the following statements about lab safety is FALSE?   a.Use of contact lenses is not allowed even when safety goggles are used during experiment. b.All chemicals in the laboratory should be considered dangerous. c.Each reagent should have its own designated pipette. d.Any excess reagents used should be returned to the reagent bottle.

Consider four distinct physical properties: boiling point, melting point, solubility, and density. Which of these physical properties do you think allows thin layer chromatography (TLC) to work? Choose one then, explain your reasoning.

When purifying a sample of aspirin that was produced in the lab, the impure aspirin sample should be dissolved in a very cold solvent, so that solid impurities can be filtered and analyzed the next day or the next week. True or False?

Instructions: a. Gather all the materials needed. b. Put the rice in a bowl then add 2 liter of water. c. Wash the rice with your hands. Leave the water to settle for 1 minute. What did you observe? d. Slightly tilt the bowl to pour out some water e. Observe then answer the following question in your activity notebook: 1. Describe your mixture? 2. How did you separate the impurities from the rice before cooking? 3. What happened to the rice? Why? 4. What happened to the impurities (husk etc.)? Why? 5. Can the solid particles be separated from the water without letting it settle at the bottom of the bowl? Why? HEAVY AND LIGHT LIQUIDS! LESSON CONGEPT:
