Nobel Prize Paper Chemicals in 3D Vision The Nobel Prize in Organic Chemistry for the discovery of chemicals in 3D vision was awarded to Derek Barton and Odd Hassel in 1969. This was the breakthrough in visualizing the way chemicals could be interpreted. Before their phenomenal discovery, people could only think of seeing a chemical such as cyclohexane in its planar, flat, 2D form. What Barton and Hassel found that was different from the universal perspective of this chemical was the infamous…

blood is a substance; however, he or she is incorrect. Substances and mixtures are both types of matter that act in different ways. A mixture is a combination of two or more substances that are not combined chemically. Furthermore, substances cannot be separated by physical means, whereas mixtures can. Because it contains many substances that can be separated through physical means after being combined, blood is a mixture instead of a substance. Blood has different components, or substances,…

Unit/Topic: (Alternate conception): ‘Mixtures are only used for cooking’ Year Level: 2 Students: approx. 26 Time: 40mins Context: Many younger students have only ever been exposed to the term ‘mixtures’ when referring to mixtures made in the kitchen. They often think of cakes, omelettes, pancakes; essentially anything with a ‘batter’. Students are exposed to hundreds of mixtures a day and don’t know it because they have simply never been told otherwise. This is how I believe the alternate…

you're suddenly handed a mysterious vial that inside holds a white mixture. You’re told that you have to figure out what is in it using physical and chemical properties to help you! What is a physical and chemical property you may be asking. A physical property is something you can touch, feel, smell, hear, and see so you’re using your human senses. A chemical property is when the physical property has been changed and now you see gas being produced, temperature changes, and smell different…

conflict and stirred up arguments, socially, economically, and environmentally. Unwanted chemicals from various experiments and projects from different companies and groups were dumped at a waste site in Niagara Falls, New York, thinking the landfill would cause no harm. The chemicals were then, out of sight, out of mind. When the area was turned into a neighborhood, it then became evident those discarded chemicals were dangerous to the health of those around through an increase of cancer,…

What is a chemist? A chemist is a scientist that studies, physical and chemical properties of different forms of matter. There are two profound chemist whose findings were crucial to today's understanding of chemistry. There names were Marie Curie and Dimitri Mendeleev, both chemist made significant impacts on modern day science and society. Dmitri Mendeleev is responsible for the creation of the periodic table, while Marie Curie is responsible for discovering radioactivity, which advanced the…

1. Is mercury an appropriate target for AGI? Why or why not? Please clearly cite examples for your reasons. (10 points) There are many reasons that mercury is an appropriate target for AGI. • Both companies are in the same industry of footwear products. • First off the two companies have differentiating strategies and markets that they sell to. AGI will be adding a new market to their company goals and increasing their revenue streams. • AGI strives in the casual footwear segment with a…

structure of elements and compounds, thereby; chemists use this information to develop new materials and substances. There are a number of career paths in chemistry such as biochemistry, industrial chemistry, electrochemistry, polymer chemistry and much more. While all the other field names speak for themselves, industrial chemistry deals with the large-scale processing of chemicals and chemical products for industrial and consumer uses. Industrial chemistry plays a vital role as an applied…

make up substances that can be pure substances such as Mercury, Iron, gold biscuits or mixtures such as air we breathe, food we eat and water we drink. A substance is a kind of matter that cannot be separated into other kind of matter by any physical process. For example sugar or salt solution, air, water, water in oil. A pure substance consists of a single type of particles (Elements and Compounds).Mixtures are substances formed when different kinds of particles come together. When a substance…

Background Research Chemical kinetics is the research of chemical processes which relates to the mechanisms and rates of chemical reactions (Sciencebuddies). The mechanisms describe variations of each molecule during the chemical action such as which bond is broken, which bond together newly, and how the three-dimensional shape of the chemical changes (Sciencebuddies). The rate of the reaction is measuring the speed of the chemical reactions (Sciencebuddies). Study of chemical kinetics would…
