would have otherwise died without. A hydrogen bond is the electromagnetic attraction exerted between polar molecules where hydrogen is bound to a larger atom. An example of this would be a hydrogen atom bonding to an oxygen or nitrogen atom. A water molecule is formed by 2 negatively charged hydrogen atoms attaching to a positively charged oxygen atom. This is why hydrogen bonding is such an important concept in The Martian. Mark Wattney had to use hydrogen bonding to create water. Wattney knew…

Introduction A reaction in organic chemistry that involves a simultaneous 3 pi bond shift is Diels-Alder cycloaddition, where a conjugated diene and an alkene with an electron withdrawing group (a dienophile) will react to form two carbon-carbon single bonds at the expense of the one carbon-carbon multiple bond to most often form a 6 membered ring adduct (Ketcha, 106). A conjugated diene is a hydrocarbon the contains two carbon-carbon double bonds and a dienophile also means “diene-loving”…

machines are large, tube-shaped magnets. An MRI scanner contains two powerful magnets, which represent the most critical part of the equipment. The human body is largely made of water molecules, which are comprised of hydrogen and oxygen atoms. At the center of each atom lies an even smaller particle called a proton,…

Fluorite, also called fluorspar, is a mineral that is composed of calcium and fluorine. Pure fluorite is colorless. Fluorite is known as the most colorful mineral in the world. Each colored fluorite has its own name. The most common colors for fluorite come in purple, blue, yellow, or green (King, Fluorite.) What makes fluorite colorful depends on what elements are substituting calcium in the crystalline structure. Fluorite is an interesting mineral because of its wide range of uses. People use…

What is chlorine and how does it have an impact on humans’ health and the environment? Chlorine is a chemical element that was discovered by Carl Wilhelm Scheele in 1774. Its symbol is Cl and its atomic number is 17. Chlorine has the physical form of a diatomic greenish-yellow gas at room temperature and atmospheric pressure. 1. 2. Indeed, its name is derived from the Greek word ‘chloros’, meaning ‘yellow-green’. 3. In the Periodic Table of Elements, Chlorine is found in the P-block, in group…

The examination, called LHCb trial, is one of seven molecule material science indicator tests in the particle smasher. The LHC united several researchers from around the globe to cooperatively think about information from the atom smasher with an end goal to comprehend what happened after the Big Bang that permitted matter to survive and fabricate the universe. In the LHCb test, researchers sent two proton bars zooming at close light-speed around the roundabout quickening…

includes atoms. These atoms all have the same amount of protons. 3. A compound is formed when two or more separate elements combine and mix together. An example is pure table salt. Table salt is created by two elements which are sodium and chlorine. Sodium and chlorine combine and mix together until the end result which is the table salt. 4. Atoms are the units of life that are considered basic. Atoms relate to elements because elements consists of one specific kind of atom and the atoms…

Scientist Contribution Significance Lavoisier (1743-1794) Antonie-Laurent Lavoisier was born on August 26, 1743 in France’s capital city, Paris. One of his major discoveries was the founding of the law of conservation of mass. This law states the weights of reagents and products are conserved through any chemical reactions. This is demonstrated through his combustion experiments. He pointed out that combustion requires air, since the reactants are weighed heavier than its products. This…

Introduction In this lab, the size of atoms and molecules in solids and liquids were estimated by using the cubical and spherical atomic model. The former model was used in a simple experiment that calculated the displacement in water and in this case, Aluminum and Copper were used. The spherical model was performed by finding the amount of amount of empty space within a sample of Lead shot. The molecular size in liquids and solids was found by calculating the density and molecular size of…

The periodic table is a very familiar site for many people, and almost all of us have spent a lot of time staring at it in Chemistry classes during our time in high school or college. The periodic table is an extremely important tool and is a great way to help students visualize a large volume of information about the elements and their relationship with each other. During your time learning about the periodic table you likely didn’t spend a lot of time looking at the elements with an atomic…
