Oxidation:
I have heard this word when people talk about things like rust, as rust is caused by oxidation. When I think about oxidation, I always think about how The Statue of Liberty is green. According to the book, oxidation is a process in which an element’s oxidation number is increased by the loss of electrons. Oxidation is an important chemical process to chemists as oxygen is a main gas in our atmosphere. The everyday and technical meanings of oxidation are very similar as they are the same thing. The difference is that most people may not know that rust or the reason the Statue of Liberty is green is because they are oxidized.
Reduction:
I have seen this word in many classes, like math. In everyday terms, reduction is subtracting or reducing something, such as numbers or people. To chemists, reduction is the process in which an element’s oxidation number is decreased by the gain of electrons. The technical and everyday definitions of reduction are the same; it is just what is being reduced that is different. The everyday term is more broad, while the chemistry definition is specific. As the two definitions are very similar, I feel as though I will be able to remember them easily.

Acid according to Chapter 7, is a substance that will dissolve in water to yield hydronium ions. Acids may be classified as strong (fully react with water) or weak (partially react with water) based on generation of hydronium ions. An everyday example of an acid that comes to mind is that of citric acid from fruits like lemons. This is a weak and organic acid, although I would originally assume it would be a strong acid based on eating lemons (which I love!).
Base according to Chapter 7, is a substance that dissolves in water to yield hydroxide ions. Bases may be classified as strong (completely dissociate in water) or weak (partially dissociate in water). An everyday example of a base is baking soda or sodium bicarbonate. This makes sense to me as I know you can utilize baking soda to subdue acids when cooking.
For both acids and bases, I recall that they are scaled on pH ranging from 1 (Acidic) to 14 (Basic) with 7 being the median (Neutral). For my current work as an RN, I often assess the pH or the CO2/HCO3 level of a patient to figure out if they are respiratory or metabolically acidotic or alkalotic (basic) to guide treatment.

Educators can foster critical thinking by encouraging open-ended discussions, pay someone to take my online class presenting real-world problems, and providing opportunities for analysis and reflection within the curriculum.

Free Radicals: When it comes to the term free radicals, I believe I have some sort of previous knowledge due to taking previous chemistry courses. I believe the everyday usage of this term would be to Signal your body’s defense mechanisms but could also be harmful to the body in high concentrations such as smoke, pollution and more. I believe the way a chemist would use this term is that a free radical would be an antioxidant that plays a very important role in protecting ourselves from free radicals. I believe that the difference between everyday usage and the technical term is that there is a difference when it comes to specificity of it. The textbook would describe a free radical as a molecule, an ion or atom that has opened an electron shell or an unpaired number of valence electrons. I believe the similarity in this would essentially be the meaning of protection. For this discussion I did have to do some research on this but I believe this course will help me have a better understanding since I only have very minimal knowledge. 
Vector: For this term, I believe I have a decent amount of knowledge due to taking microbiology and previous chemistry courses. In medicine, a vector is defined as a carrier of disease causing agent from an infected individual to something or someone who is not infected. We can also see this when it comes to food and environment. An example of this would be how mosquitoes are the vector that carry malaria and transmit it to humans through a mosquito bite. I feel with this term that there is not too much of everyday usage, but I do believe there are similar things that we use which can be related to this. When it comes to directions, a GPS is something that gets us from point A to point B, the same way a vector transmits a disease from one to another. for the way a chemist would use this term, I would Define it as a quantity that has both magnitude and direction as well as used to specify a position, velocity, and momentum of a particle. I believe this is a term which is related to the course outcomes due to how the chapter talks about its measurements of a particle. Through the few weeks before in this course, we have discussed atomic structure, and now we can use this term with how it relates to atoms. I believe the difference is how everyday language people don’t use the actual term vector, but real life examples. I believe the chemistry technical term is different due to its more descriptive definition which relates purely to chemistry. Because I only know chemistry, I feel like I have a good understanding. I do believe in this case I would need to differentiate the chemistry usage of this term versus the medical usage of this term. 

 Hey fellow Montrealers! I’m relatively new to the city and I’m curious about the weed delivery scene here. Can anyone recommend reliable and discreet weed delivery montreal? I’m looking for a service with a good selection, reasonable prices, and preferably quick delivery. Any insights or personal experiences would be greatly appreciated! Thanks in advance!
