Chemical Reactions And Functions Of The Chemistry

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:

This paper is about chemical reactions and chemical reaction types. All the data gathered was from conducting multiple experiments. Each experiment was performed carefully and analyzed to obtain the necessary information for the paper. That information included the four signs of a chemical change, the rnx type, and more.

This experiment was performed to become familiar with chemical formulas and the processes for the chemical reactions. By breaking down the chemicals, we were able to obtain certain reactants that were already part of the product. In three trials, the zinc chloride’s mass ranged from 1.16 g to 1.62 g. Mass of the chlorine found in the zinc chloride ranged from 0.66 g to 0.96 g. In the three trials of the copper sulfide lab, the copper sulfide’s mass ranged from 2.38 g to 3.18 g. The mass of the sulfur in this lab ranged from 0.64 g to 1.51g.

Atoms are the microscopic building blocks of all matter in the universe. Everything around us are made of atoms, including radiation. The centre of an atom is called the nucleus, it is made of two particles: protons, which carry a positive charge and neutrons, which have no charge. Electron carry a negative charge and it is outside of a nucleus. The attraction of these negative electrons to the positive nucleus is what keep the atom together. All the atom of the given elements has a specific number of protons and neutrons, but sometimes it will have too many of those and become radioactive and an unstable atom is called a radioisotope. When radioactive want to be stable again, they must release energy until they get back to a balanced state.

An isotope is a variant of an element that has a different number of neutrons. Every isotopes of an element will have the same number of protons in each atom. Isotopes can be classified as either stable or unstable. When an isotope is unstable, it is radioactive and will decay over time. A half life is how long it

Chemical reactions are important.Without a freezer coud ylou have nice cold ice cream and without an oven could you have roast chicken or oven fries and the answer is no. Ovens and freezers are very similar as inside heaps of chemicals are reacting to the food so it is either hot or cold.

. There are four reactions that took place in this experiment. The first reaction is a redox reaction. When the Nitric acid was added to the copper wire in the beaker electrons were transferred from copper to nitrogen. The second reaction that took place is the double replacement precipitation reaction. This occurred when NaOH was added. Both the hydroxide and the nitrate ions exchanged and the copper hydroxide ions precipitated forming a solid. When the solution was heated, decomposition took place. The hydroxide ions in the copper hydroxide broke apart and left one oxygen atom which combined with copper to form copper oxide solid. The last reaction was the acid base reaction. This occurred when Sulfuric acid was added, the sulfate

As explained earlier Uranium-235 is the main isotope used, being found in nature only .709% of the time, however other isotopes such as Uranium-238, being found 97% of the time, and Uranium-239, at about 2% of the time, are given off9. The name of an isotope is determined by the mass of that isotope. For example, uranium-235 has a certain number of protons and neutrons that add up to 235 hence the name. The only difference between the isotopes is the number of neutrons and protons each one has which determines its reactivity; all isotopes have the same atomic number12. The more neutrons and protons difference there is within an element the more reactive it will be in thermodynamics and nuclear forces that act upon it. Isotopes however are used in more than just nuclear chemistry; they are used in medicine for treating brain tumors and in determining the age of

A “Chemical Reaction” is where substances interact, producing a chemical change and altering their original molecular or ionic structure to a new one having a different chemical identity.

A major characteristic of radioactive material is that it decays from one element to another through particle and gamma decay. Essentially, all radioactive materials are byproducts of previously decayed elements. In order to utilize the radioisotopes of their choice, providers must artificially employ forms of specific radionuclide formation. This process is induced in a variety of ways, namely, production in a particle accelerator or creation in a nuclear reactor.

Radioactivity is defined as “the spontaneous emission of particles”. (Nuclear Energy). Radioactivity is caused by an unbalanced nucleus in the cell. This happens because there is either an uneven number of protons and/or neutrons. When this happens, the element is considered to have multiple isotopes. An isotope is an atom with the same number of protons but a different number of neutrons. Thus, they have different atomic weights. This is important to know because there is a such thing as a radioactive isotope. These elements just have additional energy, and they release radiation in different forms. “There are over 800 radioactive isotopes, some of which are natural and some synthetic.” (Helmenstine). Radioactive elements can be both artificial and natural. However, in medicine, most of them are more than likely synthetic, since they are the most popular types.

Nuclear reactions happen when there is a rearrangement of the neutrons and protons of the reacting nuclei to form the product nuclei. When the bonding energy of the reactants is less compared to the binding energy of the products, the excess energy is thus released in the form of radiation. As the bonding energy of nuclei is nearly a million times greater compared to the energy consumed by a chemical bond, the energy released in nuclear reactions corresponds to about a

Thermochemistry deals with energy and how it changes. We performed chemical reactions in a calorimeter, which is a device scientists use to determine the amount of heat produced by a process (or change). Processes that absorb energy are endothermic and processes that release energy are exothermic. Endothermic, processes that absorbed energy produced positive results. Where as, exothermic, processes that release energy produced negative results. This experiment also dealt with specific heat. Specific heat is the amount of heat gained or lost when one gram of a substance changes temperature by one degree Celsius. Our experiment this week explored these concepts.

There are also some elements that are not a part of any type of family. These elements are mostly other metals that are located right after the transition metals. There are some nonmetals that are included in this group. Some of these nonmetals include silicon, nitrogen, carbon, and phosphorus. All elements in this group are some what reactive. Nitrogen is the most common element. Compounds using nitrogen consist of silver nitrate, potassium nitrate, and nitric oxide. Silver nitrate is used in many different chemistry labs.

Chemistry is a very integral part of the culinary arts. The main chemical reaction in cooking is the Maillard Reaction, biochemistry second major discipline of cooking and it involves studying the bacteria, fungi, and mold that comes on to food when it is exposed to air for periods of time, and molecular gastronomy is the final discipline of cooking and is the more innovative way of cooking that involves using more scientific methods in order to preserve texture, and flavor.
