LAB 4 Observations of Chemical and Physical Change Part 1
LAB REPORT 4 Observations of Chemical and Physical Change PART 1 ââ¬â OBSERVATIONS OF CHEMICAL CHANGE No credit will be given for this lab report if the Data section is not completely filled out and if the required photographs are not received. At least one photograph must show the studentââ¬â¢s face. OBJECTIVES 1. Observe physical and chemical changes. 2. Define physical and chemical change. 3. Identify the relationship between a chemical change and a chemical reaction. 4. Observe several indicators of a chemical reaction. 5. Associate chemical properties with common items (food, household products). PROCEDURE Please complete the entire experiment as instructed in the lab manual except for any modifications noted below. Fill out theâ⬠¦show more contentâ⬠¦Define physical change. . A chemical change is usually reversible change in the physical properties of a substance, as size or shape. 2. Define chemical change. A chemical change is usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance.Show MoreRelatedPhysical and Chemical Change Lab1321 Words à |à 6 PagesPatrick Kelly 10/16/12 Physical and Chemical Changes Lab Question: How do you distinguish a physical and chemical change? Hypothesis: If we use these materials and use magnets, water, burners, and filters on the mixtures and elements given we should determine what kind of effect these materials given will have on these mixtures and elements, physical or chemical. Procedures: -Part A: Record all observations of Part A in Data Table 1 1. Label each substance on seven pieces of paperRead MorePhysical and Chemical Changes1253 Words à |à 6 PagesTitle: Physical and Chemical Changes Purpose: Recognize and distinguish between chemical and physical changes Apparatus and Material: evaporating dish, Bunsen burner, wood splint, test tubes, micro spatula, dropper, mortar and pestle, test tube holder, safety goggles, lab apron. Piece of paper, NaCl (sodium chloride), water, 6 M HCL (hydrochloric acid), 0.1 M AgNO3 (silver nitrate), Mg ribbon, 6 M HCL (hydrochloric acid), CuSO4 5 H2O, 0.50g iron fillings, 0.50g of powdered sulfur, magnet,Read MoreLe Chateliers Principle1537 Words à |à 7 PagesPurpose: The purpose of this lab is to develop a deeper understanding of LeChatelierââ¬â¢s Principle by observing several systems at chemical equilibrium and interpreting the effects of varying concentrations and temperature. The principle states that if systems at equilibria are altered or disturbed in any form, the equilibria will shift to reduce the disturbing influence ( Catalyst, 186). In a 3 part experiment, we analyzed the outcome of changes in reactant and product concentrations, equilibriumRead MoreThe Effect Of Cellulose On The Chemical Equation933 Words à |à 4 Pagesoff light and heat. Burning is a chemical change for new substances are created that cannot changed back are formed. Oxygen is needed for combustion or also called rapid oxidation. When oxygen is added, it causes a fire to burn hotter and faster. In this lab both wood and steel wool were burned in pure oxygen and air. Wood is mixture of many substances but for this lab we will focus on the cellulose aspect for the chemical equation. Cellulose has the same chemical formulation as sugar of C6H12O6Read MoreQualitative Observation Of A Chemical Reaction Lab Report1343 Words à |à 6 PagesQualitative Observation of a Chemical Reaction Purpose: Carefully observe and interpret a chemical reaction. Apparatus: Equipment- 250mL beaker, 125mL Erlenmeyer flask, cardboard square, chemical scoop, metric ruler, lab countertop, rubber stoppers, safety goggles, lab apron Materials- candle ( 2cm diameter), matchbook, 2 toothpicks, Limewater solution, string, aluminum foil, Cobalt Chloride paper Procedure: Note appearance, odor, and feel of the unlighted candle. Heat the bottom of the candleRead MoreClass Action Lab Report Essay examples1100 Words à |à 5 PagesJoseph Sulaiman Alya Abourezk 4/13/12-4/14/12 Class Action Lab Report Purpose: To determine, through observations, the identity of substances produced in a chemical reaction. Materials: Safety Goggles Stirring rod Magnesium ribbon Solid CuSO4â⬠¢H2O Matches Test tubes Copper metal 3M HCl Red and blue litmus strips 0.1M AgNO3 Zinc metal 0.1M Pb(NO3)2 Test tube holder 0.1M KI Bunsen burner 0.1M Na2NO3 Crucible tongs 1.0M NaOH Water (H2O) 0.1M Ca(NO3)2 50mL beakerRead MoreExtraction Of Salt From A Mixture. Priscilla Etim. Thursday1551 Words à |à 7 PagesThese particular qualities are identified as either physical or chemical properties. Physical properties are properties which do not require a chemical change of its composition in order for the substance to be classified. A few examples of physical properties include color, density, odor, boiling point, melting point. On the other hand, chemical properties are vastly different. Chemical properties are characterized by a complete chemical change in composition with other substances. Such propertiesRead MoreOrganic Chemistry Lab Report4021 Words à |à 17 PagesOrganic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way itââ¬â¢s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings. 1. Your work is uniqueRead MoreProperties of Gases1568 Words à |à 7 PagesPurpose: The purpose of this experiment was to test and observe the physical and chemical properties of gases, and to use these properties to identify these gases when they are encountered. Procedure: Create a data table similar to that in the lab assistant to record your observations. Gather the following lab equipment: Goggles, test tubes, 24 well plate, Gas assembly with copper and plastic tubing and a #00 stopper, short stem pipet, rubber stopper #00 with one hole and a pipet tip withRead MoreLabpaq725 Words à |à 3 Pagesfor Experiment # 1 Properties of Gases Students Name Lisa Anthony 20/20 Date of Experiment 09/29/2013 Date Report Submitted Please leave nothing blank Title: Properties of Gases Purpose: To investigate some physical and chemical properties of gases To use these properties to identify these gases when they are encountered Procedure: Have you made any changes to the procedure? Please explain. If you made no changes, state so. (1 point) No
