What is calibration and why is it essential in relation to food analysis? Provide examples.

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.

The table shows the tensile stress-strain values obtained for various hypothetical metals. Based on this, indicate which material will be the most ductile and which the most brittle.

What is green chemistry? Choose the BEST answer. O Chemistry that uses only recycled chemicals. O Chemistry that makes something green in color. O Chemistry that comes from plants or uses plant materials. O Chemistry that uses non-toxic, non-harmful chemicals.

The plot below from your book does NOT have data for ammonia. 1.0 T2.00 T1.50 0.8 T-1.20 0.6 T1.10 0.4 • Nitrogen * Methane a Ethane o Ethylene - Propane an-Butane - Isopentane n-Heptane . Carbon dioxide *Water 0.2 T=1.00 0.0 4. PR However, you can use this plot (an example of the law of corresponding states) to calculate the molar volume (V) of ammonia at a temperature and pressure of interest. What information do you need in order to do this? O The critical temperature and pressure for ammonia. The standard molar Gibbs energy for ammonia. O The normal boiling point for ammonia. O The vibrational spacing in ammonia.

Identify and provide an explanation of what “Separation Science” entails and its importance with the respect to the chemical analysis of food. Provide an example.
