Based on this information, do you think that the mole should be considered a base unit in the SI system? Explain why or why not.
In the SI system of units, the mole is one of seven base units. It is frequently used in chemical calculations. However, a mole of something is just a particular quantity of it. It is not a unit of measure in the way that meters, seconds, and kilograms are. Calculations performed with the number of […]

What is the relationship between population control and greenhouse gases?
Overview Imagine you have been hired as a consultant for the United Nations. You have been asked to write an analysis on how global population growth has caused the following problem and how it affects a developing country of your choosing: A growing global population that consumes natural resources is partially to blame for the […]
How many gigatons of CO2 equivalent can be averted (Reduced/sequestered) by the global health and education?
Service-Learning Action Project: The service action project’s main point is for you to understand how the increase in carbon dioxide relates to you, and what you can do to help this huge problem that is detrimental to marine organisms in three ways, 1) increasing sea surface temperatures 2) ocean acidification, and 3) sea level rise. […]
Why fossil fuel generating electricity would be the most beneficial moving forward.
The topic I chose is on fossil fuels and why is so hard to move on from. In my paper I will argue that the real reason that we cannot quit fossil fuels is because we lack the technology and policies. This is a final paper for chemistry, the course is about applying chemistry to […]
Prepare the 3 standards in 100 mL volumetric flasks using distilled water as diluent at concentrations of 1.0, 5.0, and 10.0 mg/L. Calculate the volumes needed to prepare them first.
DETERMINATION OF FLUORIDE USING AN ION-SELECTIVE ELECTRODE PURPOSE This experiment is designed as a no-risk opportunity to demonstrate competence in calculations and performing the associated dilutions to create a calibration curve with high linearity and high accuracy (as determined by the slope of a linear regression between instrument response vs concentration). You will then apply […]
Determine key polar interactions between the ligand and the active site, and measure the distances.
Part 1. Visualisation of protein molecules and ligand interactions. Extracting the liganda)Download pdb file “6lze”(from www.pdb.org)and open it in PyMOL. There are very clear instructions on how to install PyMOL, open files and manipulate the viewin the “modellingmanual” available fromthe practical E Moodle page(Reference 1, Chapter 4). It is highly recommended that you work your […]
