(70 points) Title | How the Volume of the Slurry Mix Effected the Biogas Generator | Type of Experiment | Experimental | Background Information | Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane‚ the main component of natural gas‚ and probably the most abundant organic compound on earth. For this experiment we had created a bio gas generator. A biogas generator is any gas fuel derived from the decay of organic matter‚ as the mixture of methane and carbon

Water and me Water is a colourless‚ transparent and odourless liquid which forms the seas‚ lakes‚ rivers‚ and rain and is the basis of the fluids of living organisms. It is a chemical compound whose formula is H2O. It covers 71% of the earth’s surface and is necessary for every known organism to live. 97% of the total water found on the earth lies in the oceans. The rest of water is in the form of glaciers and ice caps (2.1%)‚ ground water (0.6%)‚ inland water (0.2%) and water vapours (0.001%).

Scientists have been continuously presented with questions regarding the mystery that is life. What is life‚ and how did it get started? Their responses to these questions has varied over the years as advances in technology have led to new evidence being brought in from a ranging variety of fields. In the summer of 1993‚ J. William Schopf‚ a paleobiologist reportedly found fossilized imprints of microbial communities between layers of rock that were 3.5 billion years old. This‚ along with other

electrophilic reaction is when the pi bond of a molecule is removed to make two covalent bonds that are bonded to two new molecules. A nucleophillic addition is a reaction that removed the pi bond from a molecule and adds covalent bonds with two new compounds. Halogenation or most commonly known as bromination is a reaction that breaks a pi bond and adds a halogen or in this case‚ a bromine to the molecule. This addition of the bromine can be very steroselective. Stereoselectivity can come from

Kayla Adkins Forensic Chemistry Exam 2 I have been honest and observed no dishonesty. 1. In specific detail‚ describe a published procedure for the definitive identification of Heroin utilizing gas chromatography-mass spectroscopy (GCMS). Heroin is a white crystalline powder with no odor and a bitter taste. It is a derivative of morphine in that the –OH (hydroxyl group) is replaced by an acetyl group‚ -OCOCH3 and has a molecular formula is C21H23NO5 with a molecular weight of 369.42

For example‚ Glucose is C H O ; it’s empirical formula is CH O. 6 12 6 2 A hydrate is a compound that is chemically combined with water molecules. In contrast‚ an anhydrate does not contain water‚ and has had all of its water removed. Purpose:

BACKGROUND/INTRODUCTION Organic chemistry is the branch of chemistry that deals with carbon containing molecules. Carbon can bond to other atoms forming multiple chains and rings‚ thus creating an unlimited number of organic compounds to exist. Each organic compound has many chemical and physical properties associated with its structure. In this experiment‚ both the boiling point and the melting point were used in order to identify different organic molecules. The boiling point of a liquid is

models of elements‚ compounds‚ and mixtures. The lab asks you to examine conceptual models of matter in which atoms of one element are represented by nuts while atoms of another element are represented by bolts. After examining each model‚ complete the following tasks: a. sketch a representative molecular picture of the model; b. describe the composition of the model in words (does the model contain atoms‚ molecules‚ or both?; does the model represent elements‚ compounds‚ or both?; does the

9405 = 24% In this example‚ the lender stated a simple interest rate of 10 percent. Yet you actually are paying an effective APR of 24 percent once you add in the fees and you do not have the use of the full loan for the entire loan period. 3. Compound interest arises when interest is added to the principal so that from that moment on‚ the interest that has been added also itself earns interest. This addition of interest to the principal is called compounding. The following formula gives you
