WWI affected the soldiers. I knew they used them, but I didn’t know about all of the facts behind the poison. These chemicals were forbid at both The Hague Declaration and Convention. Since Germany was the leading the world in science, the chemists were experimenting with different combinations of chemicals to make lethal gases. Scientists were also curious on the effects these chemicals would have on the battlefield. Considering these gases were outlawed, but were still used should have never happened

of every living thing and they help body functions occur properly. They are furthermore significant to the field of biology because they have such a large role in keeping organisms alive. This is due to the fact that they affect the rate at which chemical reactions in the body take place and “without enzymes, these reactions would take place too slowly to keep you alive”, which shows how vital enzymes are for survival (Science Museum). They can also be useful for helping create DNA and communication

it with evidence from your observation table. Test A: A chemical change occurred. I know this because bubbles formed when the two substances mixed. I also know this because a gas was formed, and an indicator of a chemical change is when a new substance forms. Test B: A chemical change occurred. I know this because there was both a production of light, and a production of heat. Also, the change that occurred is irreversible. Test C: A chemical change occurred. I know this because the mixture was opaque

Neon, mercury, and olive oil change from their natural states of matter when the temperature changes. Once the temperature does change, the particles start moving, and the states of matter change. For example, the movement of the particles in neon are limited as the temperature decreases. The particles of neon in it’s gas form go crazy and speed up, colliding into each other and spread out over all the space. Neon turns to a liquid between -248°C and -246°C. In this stage, the particles can slide

The theory of atoms and atomic history have been changing throughout history. The atomic theory has had many factors changed and restated to go along with the more recent discoveries. Today, we know all atoms have electrons, protons, neutrons, and of course, the nucleus. Those are a few of the fundamental terms we use to understand the basic structure of an atom. Those are just the simple building blocks of an atom. There is also a electron cloud that is around the nucleus. It was thought to have

After performing and collecting data from the James Bond Lab, we were able to determine that substances 1 and 7 are ionic bonds, 9 and 12 are polar covalent, 13 is metallic, and 16 is nonpolar covalent. First we came to the conclusion that #1 and #7 have characteristics of ionic bonds. Ionic bonds are conductive and soluble in water, and they also have high melting points. Ionic bonds are polar, and so are water molecules, which makes them interact. This is because polar solvents dissolve polar solutes

The purpose of this experiment was to determine the specific heat of an unknown metal we were give. With this specific heat of the unknown metal we can then determine what the unknown metal is. As for the acid-base reaction experiment we will also be conduction in this lab we will use this acid-base reaction to determine the enthalpy of neutralization of a strong acid-base reaction. By following these precise guidelines in this experiment we can then determine the energy released per mole of water

Atomic Mass as a Quasi-Periodic Trend Atomic mass is the mass of an atom, or the number of protons and neutrons in an atom. Every element on the Periodic Table has an atomic mass that is recorded as either an average decimal or a whole number. There are some numbers on the Periodic Table that show patterns or trends. When a pattern is present on the entire Periodic Table then it is called a Periodic Trend. If it is only present in a section or sections of the table it is a Quasi-Periodic Trend

Jessie Harrell Hazardous chemical project Introduction: One would never expect the everyday products they use could be extremely detrimental to their health. This is what has made triclosan so devastating. Originally crafted for use in hospitals in the 1960’s with the chemical composition shown in the image on the right, Triclosan made its way into products on the market soon after (Brouillette, 2016). Triclosan, while used to protect people from bacteria, actually has very adverse effects after

For the Identification of an Unknown Compound lab, the physical properties, along with the IR and the H1 NMR will be used to determine the molecular structure and identity of the unknown compound. For the physical properties, the smell, color, state, solubility and the refractive index will be used. Then, the IR and H1 NMR be obtained using the unknown compound given during the lab. The IR and H1 NMR will play a major role in determining the molecular structure of the compound because the stretches
