Jack Adamson || 305968 Carnelle Ancheta || 8040643 Jordan Wusthof || 2004830 Chemistry Honors Block 1 Chemical Formulas Abstract: || Jack Chemical formulas are used as abbreviated notation to show the chemical composition of compounds. 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.

What is a ratio? A ratio is a way to compare and separate the values by dividing one value by the total. What is a chemical formula? A chemical formula is a way to show chemical symbols and numbers to represent a substance. Compare and contrast the properties of water with the properties of hydrogen and oxygen. Water, Hydrogen, and Oxygen have many similarities and differences. The similarities of the 3 are that they can be turned into a gas (gas state) by this water can turn into liquid by the

In the experiment we were determining the chemical formulas for the hydrated, and dehydrated samples. The purpose of this was to asses our knowledge of chemical formulas, and how they relate to each other. We first obtained the molar masses of Copper, Chlorine, Hydrogen, and Oxygen from the periodic table in our books, and then weighed a crucible and placed approximately 1 gram of the hydrated substance in the crucible, and weighed it again. Then we heated the hydrated substance with a bunsen

purpose the determination of the chemical formula of a hydrated compound of copper (Cu) and chlorine(Cl). To accomplish this experiment, the law of definite proportions must be used. This experiment will endow a person with the necessary skills for the determination of the chemical formula of a compound, where only the general formula is known. In addition, knowledge on how to heat a compound, how to weigh a compound, how to do a vacuum filtration and how to conduct a chemical reaction will be employed

Introduction: This experiment is based on determining the chemical formula for a hydrated compound containing copper, chloride, and water molecules in the crystal structure of the solid compound, using law of definite proportion. The general formula of the compound is CuxCly•zH2O, and aim is to determine chemical formula of this compound. Law of definite proportion, sometimes called Proust’s law, states that a compound always has exactly the same proportion of elements by mass. This

Purpose Statement: In this experiment, we will determine the chemical formula of an unknown hydrated copper chloride compound which is composed of copper and chlorine. We will use stoichiometry, which is the relationship between quantities of materials in a chemical reaction, to determine the chemical formula for a compound. We will use the mole to mole conversion to find the formula of a hydrated compound with the general formula CuxCly.zH2O. We will convert the masses of water, copper, and chlorine

BAD What is the chemical composition/formula of it? (Is it ionic/molecular, neutral, and acid or a base?) Caffeine (C8H10N4O2) is a molecular compound however it forms ionic bonds. It is an alkaloid which means that it is an organic nitrogen containing a base. Caffeine is only slightly basic. Where is the compound/element found? Caffeine is found naturally in many trees and plants. Currently, environmental issues including deforestation, pesticide pollution, habitat destruction, soil and water

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H, it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s, it is organic. Use the naming organic compounds rules. *

1. The chemical formula for sodium hydroxide is NaOH. It has a ph of 11 and is considered as a base. The chemical formula for hydrochloric acid is HCl and it has a ph of 2 and is considered as an acid. The chemical formula of ammonia is NH3 and it has a ph of 8 and is considered as a base. The chemical formula of sodium chloride is NaCl and it has a ph of 7 and is considered aa a base. The chemical formula for deionized water is H2O and has a ph of 7 and is considered neutral. The 7up had a ph of

Benzene Chemical Report Duncan Fraser Contents   What is benzene Benzene is an organic chemical with the chemical formula of C6 H6. It is a chemical that appears as a colourless liquid or sometimes slight yellow at room temperature. Benzene boils at 176.2 degrees Fahrenheit and freezes below 41.9 degrees Fahrenheit. It has a sweet petrol like odour and is highly flammable. The hydrocarbon is derived from benzoic acid and is therefore named benzene. Michael Faraday an
