Stoichiometry

before doing it. This way, I could have a better idea of what to look at while conducting the experiment. I completed background research on baking soda and vinegar, CO2 production from their reaction, base and acidic substances reacting, and stoichiometry of baking soda and vinegar reactions. After doing research, I found many interesting facts and information. First I researched vinegar. It is an alcoholic liquid that has been allowed to sour. Vinegar is acidic; it has a pH of 2-3 (Decelles…

Introduction Section- The purpose of this experiment is to use reaction stoichiometry to determine the molar mass and the identity of an unknown, powdered metal, and to identify an unknown metal nitrate solution. To give a little background information on this experiment I will start by saying that a balanced chemical equation provides several important pieces of information about a chemical equation. Those important pieces include the substances consumed and formed, the physical states of the…

neutralization reactions using phosphoric acid, which is a triprotic acid, with different volumes of sodium hydroxide. Introduction When looking at the coefficient of balanced equations, stoichiometry is seen. Coefficients represent the number of moles, equivalent to the mass of an atom, of the products and reactants. Stoichiometry was demonstrated in this experiment to determine the relationship between the testing agents. A polyprotic acid or base is used because it is able to react with…

The number of moles of hydrochloric acid neutralizes for the three trials (2,4,5) were calculated using stoichiometry. It was calculated for trial 2 by convert 4.88 mL NaOH to L by divide by 1000 mL. Then, to get to mol of NaOH the molarity of NaOH was multiplied by 0.00488. Then to get from NaOH to HCl, the mole ratio 2 HCl to 1 mol NaOH was multiplied by 0.00122. To get the amount of HCl per beaker, 100 mL of HCl was divided by 1000 mL to get 0.1 L. Then, the liters were converted to moles by…

reaction and stoichiometry mixture Na2CO3 and NaHCO3. To do the lab by using the constant mass. Constant mass is a quantitative chemistry technique where a single chemical species or group reactants is heated with constant weighing until the mass does not change. After heated the Na2HCO3 will undergo a decomposition and Na2CO3 will not undergo reaction. The balanced equation is 2NaHCO3NaCO3+H2O+CO2. Find the mass percent position use the balanced equation and stoichiometry. Stoichiometry is the…

cooked. It is used in our everyday life when because you need chemistry to do everything. Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound. The coefficients in a balanced chemical equation represent moles of reactants and moles of products. The mole ratio of reactants and products in a balanced equation must remain constant. Stoichiometry relates to cookies because all the ingredients mixed together make the cookies.…

find ways to dye, coat, blend, or invent materials both naturally and synthetically through textile chemistry. Eventually they will find the perfect combination to reach their goal. 2. Explain the concept of stoichiometry. ● Stoichiometry is the 5th chemical engineering principle. Stoichiometry is the mathematical understanding of how two materials relate to each other and the specifics of their reactions used to increase knowledge. The literal definition of this term is “measured element”. In…

The purpose of the lab was to find which of the three balanced chemical equations was correct using decomposition & stoichiometry. After getting the necessary supplies for the lab, get the crucible and weigh it on the scale. After that, reset the scale so that it shows all zeros. Then put a certain amount (10,00 g), set up the ring stand and bunsen burner, so you can heat the crucible and baking soda effectively. The lab procedure and data supports the hypothesis, that if baking soda is heated,…

It is up to the teacher who is teaching stoichiometry to the students to minimise the amount of misconceptions by using specific teaching strategies and methods that work in way that don’t open any doors for confusion or false ideas. This can be difficult for teachers as in many cases, teachers when they are getting their degree in teaching or carrying out the masters in education are often taught the content area, but not how to teach the content in such a way that makes it easier on both them…

Everyone has a belief that helps them achieve their goals. My personal belief is not giving up and always giving 100% effort. These beliefs had helped me get through some difficulties throughout my education prior to college. Some examples of when I have put my beliefs into practice is during 6th grade in english class, and in 10th grade in my chemistry class. One subject that I am weak in is in english. I was never that good in english. English class was generally boring and hard back then. By…
