Stoichiometry Lab Report

In this Chemistry Lab the main objective is to perform accurate chemical analysis for the quantity of elements and compounds in a sample. There will be a compound made then synthesized. The methods used were acid-base titrations, redox titrations, gravity filtration, and distillation. General conclusions included

Ratio between the amounts in moles of any two compounds involved in a chemical reaction.

In this experiment, we learned about stoichiometry, empirical formula, molecular formula, polyprotic acids and bases, metathesis reactions, and moles.

The method of continuous variation is able to be used in order to determine the mole ratio of reactants in a chemical reaction. This is done by measuring the change in temperature. Due to the reaction producing heat (exothermic) and the total volume of the solutions being kept constant for all measurements, the heat produced is proportional to the amount of reaction that occurs as well to the extent that the reaction occurs. This then helps to find the greatest amount of reactants consumed and the greatest amount of product formed which ultimately identifies the optimum ratio of the two reactants.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

The Empirical Formula is a formula that shows elements in a compound. The molecular formula gives the amount of atoms that each element has in a compound. These formulas were used to calculate and find elements that were given prior to the crash. The formulas also helped our team find out which passengers had each of the possible materials on the flight.

Using elemental analysis to determine the percent mass composition of each element in a compound is the first step in creating an empirical formula. There are many different types of elemental analysis, but in this experiment gravitational analysis and Beer’s Law are used. Elemental analysis is first used to find the moles of each element, then converted to mass, and then the percent mass of the element in the product is found (2).

During this lab I learned how to convert the mass of a compound to the number of moles and then to the number of molecules, I also learned how to determine the concentration of a

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors.

Stoichiometry is a method scientists use to presume how two or more substances will react together. In order to do so successfully, the reactants are positioned on the left and the products on the right. The most important part of successfully

Stoichiometry has many uses in the real world. In the chemical industry and in professional scientific experiments, scientists use stoichiometry to save money. Scientists use stoichiometric calculations to determine the amount of a substance they need to purchase for a specific reaction. There are four possible reactions that can occur when sodium bicarbonate thermally decomposes. In this lab, stoichiometry was used to find out which balanced chemical equation out the four best represents the thermal decomposition of sodium bicarbonate.

Chemistry is a subject most people find difficult, somethings can be confusing and other just not make sense. To clear up some of these topics, past chemist have come up with laws. Three different laws to be exact, these laws were used and are still used to help people when combining elements. Each law is used for separate purposes composed by separate chemist; the first law is the law of definite proportions, the second is the law of conservation of mass, and finally the third is the law of multiple proportions. In this essay I will be discussing and describing each law and there purpose in chemistry.
