Investigating The Mechanism Of Decomposition, Reaction Energetics, And Gas Evolution Of A Material

Temperature is a measure of kinetic energy. As this movement increases, collision rate and intensity, and therefore reaction rates, increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate an increase in temperature will increase reaction rates until proteins denature.

Temperature is known as one of the factors that affect the solubility of a gas in its solvent. Because the enthalpy of solution for gases dissolved in waters is usually

Hypothesis: If the temperature (I.V.) of materials in the reaction are increased, the reaction time (D.V.) will decrease.

Experiment 2: Water Treatment, used 100 mL potting soil, (2) 250 mL beakers, (2) 100 mL beakers, 100 mL graduated cylinder, 40 mL sand, 20 mL activated charcoal, 60 mL gravel, 1 wooden stir stick, alum, a funnel, cheesecloth, bleach, a stopwatch, and water. First, 100 mL of soil was added

The experimental procedures for Lab 2 were provided on Blackboard labelled as “Pre-Lab 2: Techniques & Measurement”.

Heat is a form of energy, sometimes called thermal energy, which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact, they will, given sufficient time, both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured in a device called a calorimeter, an insulating container that minimizes heat exchange between its contents and the surrounding. Heat flow in a device called a calorimeter. In this experiment, we should find the heat capacity of the

Another example where temperature is used to speed up a chemical reaction is powering a car. The engine burns

I also did a couple of additional characteristic property tests just to make sure that I wasn’t Identifying my solid wrong. Since this solid was a powder it was a bit difficult to do the reaction to flame characteristic property test. But I managed to do it and the solid was becoming even more darker than how it normally is when you put it in the

The sample received was in a chunky form and was crushed to powder to be used in this study. However, further purification was not performed. It contained 95~100 % montmorillonite and 1~2 % quartz with a chemical composition of 60.4 % SiO2, 17.6 % Al2O3, 0.24 % TiO2, 1.42 % Fe2O3, 0.10 % FeO, 0.08 % MnO, 6.46 % MgO, 2.82 % CaO, 0.06 % Na2O, 0.19 % K2O, 0.02 % P2O5, and 0.29 % F in weight. Its reported CEC and SSA values were 1.2 meq/g and 97 m2/g, respectively, with Ca as the major exchangeable cation (Clay mineral

Temperature is a measure of the average kinetic energy of the particles in a body. Temperature can be understood by recognizing that a hot object contains more thermal energy than a cold object. The amount of thermal energy in a substance is affected by the amount of particles that are in it. Temperature is independent of number of particles in

From the ancient time marble is one of the most important materials used especially for decorative purposes. However its powder has bad effects on the environment, soil, water and health problems. Marble powder is produced from processing plants sawing and polishing of marble blocks. Some factories have water recycling plants containing flocculation tank and filter press unit. About 25% of the processed marble is turn into dust or powder form. About 7,000,000 tons of marble have been produced in the world. Disposal of the marble powder material of the marble industry is one of the environmental problems worldwide today. The refining of some fresh and hardened properties of concrete is successfully and economically achieved by utilizing and

This experiment shall be repeated twice or more to enhance accuracy of the results obtained. Besides detecting systematic errors, this experiment would aid on the technique and understandings to the correct use of these equipments.

When heat is added to a substance, the kinetic energy of individual particles increases, which makes them move faster resulting in a increase in temperature. The more heat that is added per gram of substance, the greater the temperature change. The relationship between the heat added, the mass of a substance, and the temperature change it undergoes is known as the specific heat.

Purpose: This lab taught procedures for determining heat of capacity of a calorimeter and measuring enthalpy of change for three reactions. It also enforced methods of analyzing data obtained through experimentation and calculating enthalpy. These procedures are used in the branch of thermodynamics known as thermochemistry which is the study of energy changes that accompany chemical reactions. Concepts from this lab can be used to determine the potential energy of a chemical reaction. Much of the energy people depend on comes from chemical reactions. For example, energy can be obtained by burning fuel, metabolizing of food or discharging a batter.

Purpose: To create chalk (calcium carbonate) and to find the percentage yield in order to see the amounts of anhydrous sodium carbonate and calcium chloride were used up. Also to see if there’s any alterations like mass differentials.
