Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

Purpose: The purpose of the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister

Observing the and determining the reaction rate of photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is created

Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used

The purpose of this lab was to use a calorimeter to learn when energy is being released or absorbed in a chemical reaction. My lab partner and I had to determine the heat exchanged when solid magnesium hydroxide is mixed with solid citric acid‚ using a coffee cup calorimeter. Given that citric acid is soluble in water is the property that makes this reaction possible. The first law of thermodynamics and Hess’s law are also present within this experiment. Knowing the difference between endothermic

Classifying Chemical Reactions 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. Apparatus: • Bunsen or lab burner -Test tube clamp • Butane safety lighter - Test tube rack • Evaporating dish - Wash bottle • Forceps or crucible tongs - Wood Splints • Heat resistant pad • Litmus paper • Pipets • Spatula • Test tubes Materials: Ammonium carbonate‚

Analysis of a Chemical Reaction Purpose: To observe a chemical reaction and to use qualitative and quantitative evidence to identify this reaction from among four possibilities. Hypothesis: I think the result is going to produce water. I think this is going to happen because there is hydrogen and oxygen inNaHCO3. Materials: -Test tube clamp - 150 mm test tubes (2) - burner - retort stand - clay triangle - iron ring - crucible Procedure: Part A: 1. Add 0.5 g of NaHCO3

Observing a Single Chemical Reaction Qualitative vs. Quantitative Observations Abstract: The purpose of this experiment is to help you sharpen your observational skills. The aluminum foil was found to rust in the water containing the dissolved Copper Chloride (CuCl₂) crystals. The results of the experiments were determined through close examination and observation of both qualitative and quantitative elements of the changes that occurred when a blue crystal‚ Copper Chloride‚ reacted with aluminum

Bags of Reactions * Problem/Purpose * Background Information: The Law of Conservation of Mass was created by Antoine Lavoisier in the 18th century. This law stated that mass could matter could neither be created nor destroyed. During a reaction the bonds of the reactants are broken and form new substances. As stated in the Law of Conservation‚ matter can neither be created nor destroyed; because of this the products should have the same number and type of atoms as seen in the reactants
