5. You will be given some samples to weigh on the electronic balance in the laboratory. Place a piece of weighing paper on the pan of the balance and push the zero (tare) button so the balance registers 0.000 g. Carefully place one of the samples on the paper and record its mass in table below. Carefully remove the sample. Repeat this procedure for the other samples. Determine the average mass and average deviation of the samples. Show all work. Record the individual masses of each item in the blanks to the left below.

The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing.  It is important to consider what the experts say, but to also evaluate their statements.  We will start with the scientific method.  I want you to outline the scientific method from what you have been taught in previous classes.  You can list steps, parts, process, short descriptions, whatever.  If not taught in previous classes, then you will make your best guess about it.

FINAL Experiment 1- January 2021_-789644623 - Saved Layout Review View Table A friend of yours went panning for gold last weekend and found a nugget that appears to be gold. With your newfound scientific prowess, you set out to determine if it is really gold. Your tests show that the nugget has a mass of 7.6 g. Immersing the nugget in water raised the volume from 7.22 mL to 8.06 mL. The density of gold is 19.32 g/cm3. What will you tell your friend? acer

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.
