Chemical formulas are used to show how new compounds are formed by chemical reactions. In order to learn how chemical formulas are written, we must first learn to understand the different symbols used to identify compounds that are formed. Introduction: || Jordan The purpose of this lab is to become familiar with chemical formulas and how they are obtained. Chemists use an abbreviated notation to indicate the exact chemical composition of compounds. We then use these chemical formulas to indicate how new compounds are formed by chemical combinations of other compounds. In this lab we took various chemicals and put them through various circumstances. After these little tests, we would look at the substance?s physical and chemical properties whilst documenting them. The most important thing we wanted to take away from this lab was what the chemical formula consists of as well as the changes of mass through the chemical?s various tests. Theoretical Background: || Jordan The formula weight of a substance is merely the sum of the atomic weights of all atoms in its chemical formula. For example, nitric acid, HNO3, has a formula weight of 63.0 amu.Show MoreRelatedGravimetric Analysis Of Copper Chloride Hydrate1086 Words   |  5 PagesChemical formulas are central to chemistry; they describe, identify, and predict the properties of compounds. Chemical formulas can be found by a process called gravimetric analysis in which components of a compound are isolated, their masses are found, and the mass differences recorded. Gravimetric analysis can be helpful when finding the formula of an ionic hydrate, an ionic crystal bound to water molecules because it allows for the mass of water to be found allowing for further separation ofRead MoreOxygen and Oxidation1581 Words   |  7 Pagesanother – and many of these reactions does not involve oxygen at all. For example photosynthesis, the process in which plants store chemical energy from light energy, involve oxidation and reduction reactions although oxygen itself is not used. Transferring electrons from one substance to another leads to a ï ¬â€šow of electrons, in other words to an electric current. Thus chemical reactions can be used to generate electricity – a simple battery works by using a reaction of oxidation and reduction in this wayRead MoreThe Chemistry Within Oncology And Cancer1174 Words   |  5 Pagescure this horrible disease(American Cancer Society, 2013). Chemistry has such a major impact on the research of cancer. The chemistry within Oncology Cancer Research has greatly increased our knowledge and capabilities for developing new treatments or actually finding a significant cure (American Cancer Society,2013).

However, understanding how health and chemistry are related demonstrates the common and also rare aspects of the human body. Heart attacks are an example of many different chemically related risks. Some of the causes may be familiar and not known as prime factors for heart attacks. High cholesterol serves as a risk factor for heart disease along with blood clots, diabetes, certain seafoods, stress, high blood pressure, and autoimmune conditionsRead MoreLab And Thanks And Gravimetric Stoichiometry1608 Words   |  7 Pagesthis experiment we explored both parts of data and collected both for each reaction we made in lab and thanks to gravimetric stoichiometry we are able to determine percent mass changes that occur in each reaction due to the simple fact that in a chemical reaction the mass is never lost its only transfo rmed, therefore we are able to make assumptions on stoichiometry as a whole and gravimetric stoichiometry to be exact. More-after gravimetric stoichiometry is the branch of stoichiometry the uses theRead MoreDaniela Galvan . Janet Pangilinan.
