Chemical Reaction Lab Report

Honors Period: 5 February 29, 2016 Chemical Reaction Lab Report Introduction 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

Hilliard Dr. Agapito Chemistry 10 February 13, 2018 Lab Report Introduction: In this activity, the group dealt with four metals and six chemicals. They observed the different chemical reactions each metal made with each chemical. In the end, the group ended up with 24 chemical reactions, each distinct to a certain metal and its chemical. The two main concepts they dealt with were Order of Activity and Oxidation State. Order of Activity is the reaction depending on the location of the element. The

to compare the results, and neither solution was expected to produce an observable chemical reaction. The procedure was the same as used for the test with 6M HNO3 and 0.1M AgNO3 solution and the test with 6M HCl and 0.1M BaCl2 solution. A third experiment used was the flame test. First, a scoopula was used to place 0.1 grams of the unknown compound in a test tube, and a wash bottle was used to add approximately 2 mL of deionized water to create a solution. The wire loop was cleaned by dipping it

Aim: To compare the mass of the products of a chemical reaction with the mass of its reactant Hypothesis: That the mass of the product will be the same as the reactants when under a closed system. The mass of the product will be different however, when under an open system. Variables: • The Alka-Seltzer Tablets must be the same and when broken into smaller tablets, no part of the antacid tablets are to be lost • The amount of deionised water that is placed in the conical flask must be the exact

observe the principles of matter and its transformation. Matter, in scientific terms, is defined as any substance that possesses both mass and volume. In this experiment, the vinegar and bicarbonate soda, both matter, undergo a chemical reaction known as an acid-base reaction. The acetic acid in the vinegar reacts with the sodium bicarbonate to produce carbon dioxide gas, water, and sodium acetate, the product of our experiment, also known as the matter. In an open system, the carbon dioxide gas escapes

has mass. All matter is made out of many tiny atoms. Chemical change is substances that change into different substances. A physical change is a substance changing its appearance without rearranging how the atoms are bonded together. The law of conservation of mass states that matter is neither created nor destroyed by chemical or physical changes. The guiding question is how the total mass of the substance formed as a result of a chemical reaction compares to the total mass of the original substance

Types of Chemical Reactions The purpose of the lab experiment was to identify different types of chemical reaction and the products of the formulas. The different types of chemical reaction include decomposition, single replacement, synthesis, combustion, and double replacement. There were many hazards that were involved in these experiments. Some of them were heat burns, base burns, alkali burns, catching hair on fire, the risk of getting chemicals in the eyes, spilling the chemicals, the risk

Introduction Chemical reactions occur all around us, even in us. Millions of reactions occur in our bodies every day, let alone outside of out bodies (ChemHealthWeb.gov, 2015). Human bodies create energy by using glucose in a series of chemical reactions to release energy. This is called respiration and it occurs in all living cells. Some chemical reactions are visible such as oxidation. This is a reaction between some metals and oxygen. Electrons jump from the metal to the oxygen and form a layer

The basis of this lab is mainly focused on the properties of chemical reactions. It is through experimentation that one will become familiar with these reactions. Reactions tend to be represented by chemical equations; however, not any equation will do; chemical equations have to be balanced according to the Law of Conservation of Mass. In this lab, various chemicals will be used and reacted in order to confirm the chemical equations. Observations and Comparisons from the products to the reactants

is putting the chemical reactions to work! We are going to be using different substances and combining them together to record and observe the different reactions that will be produced as we perform the steps. Looking at the way a substance combining with another substances that can make a whole different reaction is very interesting. The main goal of this experiment is to observe some typical chemical reactions, identify some of the products, as well as summarize the chemical changes in terms

Chemical change can be defined as a change that occurs at the molecular level, which includes making or breaking between atoms to produce new chemical substances. Signs that can indicate a chemical change are a difference in colour, change in heat temperature, gases being produced or precipitate forming. Chemical changes are categorised into 5 types of reactions; combination, decomposition, single-displacement, double-replacement and combustion. Combination reactions are when two or more reactants

Discussion: The main scientific concept explored in this laboratory was the ability to observe the chemical reaction between Fe and Cu and to determine the ratio of moles of iron used to moles of copper produced in the reaction. A chemical reaction occurred when we used 4.06 grams of copper (II) chloride and mixed it with 9.43 grams of iron nails. The copper (II) chloride used 1.24 grams of iron from the nails to produce 1.99 grams of copper solid. In order to calculate the moles ratio between

that must be present in all science labs in order to ensure full success for the lab as a whole and to keep good health. When performing labs, it is essential to be habitual to science safety manuals that vary upon lab location. The manual for secondary school students of Simcoe Country District School Board addresses significant responsibilities for students when conducting labs. One of the expectations is for students to wash their hands after working with chemicals. This is a reasonable expectation

qualitative tools to study and monitor chemical changes. By carefully measuring mass before and after many chemical reactions, it was observed that, although chemical changes occurred, the total mass involved in the reaction remained constant. Assuming this was true for all reactions, chemists transformed this observation into a scientific law; the law of conservation of matter, which states that mass is neither created nor destroyed during a chemical reaction, it is conserved. In other words, the

Chemical reactions happen in industrial processes, living systems, and chemical laboratories. These reactions are thought to form products during their processes. These reactions are called combustion, synthesis, decomposition, precipitation, single-replacement, double replacement, acid-base, and redox. Combustion is known as burning. It happens when a substance combines with oxygen, which results in the release of large amounts of energy forming heat and light. the product of combustion can be water
