Chemical Formula Review

As Nelson Mandela says: “Education is the most powerful weapon which you can use to change the world.” And you know “Science can change the world”. Science has the power to materialize dreams. It’s an engine of creation. Science makes real the things that everyone wish they had. We design the future and make it a reality. And I am a gifted student in all subjects, but I am particularly passionate about Chemistry. I constantly explore and learn new horizons of knowledge, to improve my knowledge

Nintendo Co. Ltd., ranked by IGN (Imagine Games Network) as the best video game developer of all time created the first Pokémon game in 1996. Ever since that day, Pokémon has grown to be one of the biggest video game franchises in the world, selling over 260 million copies and next to only the Mario and Super Mario franchises. Personally speaking, Pokémon has been a monumental part of my childhood, and I keep up-to-date with it even today. Pokémon video games are played on an international level

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.

attack, identification of all substances found on and in the bodies and luggages of the victims needed to be made. To do this, empirical and molecular formulas were put into use when determining substance identities. Each substance was tested to find the percent composition of carbon, hydrogen, nitrogen, and oxygen, and then used to find the empirical formula of the substance by using 100 grams of each substance to represent 100% made up by the elements combined. The mass of each element in the substance

Starting from Naphthalene, the following synthetic strategy, Figure-5, was created using techniques discovered by the national chemical laboratory. Step one is the addition of an alcohol group to Naphthalene using Toluene and 4-monooxygenase (Copley, S. D). Once 1-naphthanol is the starting material used by the nation chemical laboratory to synthesis propranolol. The following synthetic strategy is used to create propranolol from 1-naphthol: “(a) 3-bromopropanol, 10% aq NaOH

from the lab. When zinc and hydrochloric acid are mixed together, the reaction took place in an evaporating dish that was accompanied by hydrogen gas. Then we measured out the mass of zinc and chlorine in the reaction and calculated the empirical formula of zinc chloride which was ZnCl8. Based on the conservation of mass, we balanced the equation and got Zn(s) + 8 HCl (aq) → ZnCl8 (s) + 4 H2 (g). In the second part of the experiment, we obtained copper wire and sulfur from the instructor. Then we

Lab Report 1  Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment, we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper, chlorine, and water molecules

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

Chemical 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 of
