    experiment is to see if we can recycle polystyrene using acetone. If this is possible‚ this can be used to help improve our environment since polystyrene itself is not biodegradable. Hypothesis: I hypothesis that polystyrene‚ mainly known as styrofoam‚ can be recycled using acetone. This cost efficient and easy method will not only motivate both individuals and industries to recycle but also improve the state of our environment. Materials: 100% acetone nail polish remover 3 small containers 4 Styrofoam

    Kinetic Theory

    • 7 Pages

    The kinetic theory of gases describes a gas as a large number of small particles (atoms or molecules)‚ all of which are in constant‚ random motion. The rapidly moving particles constantly collide with each other and with the walls of the container. Kinetic theory explains macroscopic properties of gases‚ such as pressure‚ temperature‚ or volume‚ by considering their molecular composition and motion. Essentially‚ the theory posits that pressure is due not to static repulsion between molecules‚ as

    Use the knowledge of kinetics to explain each of the following statements. a. An increase in temperature at which a reaction takes place causes an increase in reaction rate . An increase in temperature means increasing the energy of the molecules present. If the molecules has more energy ‚ then more of the them will collide often with enough energy ‚ to overcome the activation energy barrier. causing the reaction to proceed more quickly. b.An addition of the catalyst increases the rate at which

    Iodine is an element that is critical for normal function of the thyroid gland‚ which is a key regulator of the body’s basic metabolic rate. Iodine is a micronutrient‚ meaning we require only small amounts of it. For example‚ adults need about 150 micrograms of iodine in the form of iodide ion per day. However‚ an insufficient supply of iodide via diet and drinking water causes the non-cancerous enlargement of the thyroid gland known as goiter. Prolonged lack of iodide can lead to loss of thyroid

    JULIA SELORMEY BIO 111 Iodine Description: Is a trace mineral that your body uses in small amounts to synthesize thyroid hormones that are necessary for regulating the body growth‚ development‚ metabolism and body temperature. Most of the iodine in the body is found in the thyroid gland‚ but is found also in the blood and muscles. The body contains approximately 20 to 30 mg of iodine which is mostly stored in the thyroid gland located in front of the neck. Food sources: Milk is the major

    Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate
