The specific heat capacity of a substance is the amount of thermal energy required to heat one gram of that substance by one degree. It is an intensive property‚ as opposed to the heat capacity‚ which is an extensive property that depends on the amount of substance present. In this experiment‚ the heat capacity is determined by measuring the change in temperature of the cold water when a hot metal (that does not react with the water) is placed in it. It is assumed that the specific heat capacity

Period 12 Chemical Aspects of Life & Spit Lab ABSTRACT: The objective for the Spit lab was to test two different types of crackers for the presence or absence of starch and of reducing sugars. Also‚ to test the chewed cracker‚ the one that didn’t have a reducing sugar‚ for the presence or absence of a reducing sugar with the saliva in it. Adding on‚ another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab‚ the objectives were to test for the presence

In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

Abstract The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected

Flame lab test Chemistry Introduction The lab test performed was to determine characteristic colors that were produced by specific metallic ions that are shown in a flame. This happens when an electron gains energy; the electron moves from an energy level that’s farthest away and to an empty orbital close to the nucleus with higher levels‚ so one of the electrons gives off energy. A flame test is a visual test where the energy is in the form of a color change and the change can
