are made up of an amino group‚ an R group a carboxyl group and an alpha carbon‚ the different R groups of each individual amino acids determines which amino acid they will form. Amino acids bond through covalent peptide bonds this occurs via a condensation reaction‚ which is when one amino acids hydrogen & oxygen (carboxyl group) and another amino acids hydrogen (amino group) react releasing a spare molecule of water (see figure 6) and forming the peptide bond between the carbon and nitrogen‚ going

Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Evaporation‚ condensation‚ sublimation‚ and precipitation. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = Transpiration‚ surface run-off‚ infiltration‚ and percolation. With or by adding sand and possibly plants to the assignment

which did not both bring condensation when heated and dissolve in water‚ which agreed with our hypothesis because we also thought that sucrose was going to be the only one that wasn’t a hydrate. The only error that we may have encountered in this lab was that when heating‚ the flame was not always the same temperature‚ but I feel as though this did not affect our data much because we didn’t need a set temperature‚ we were only seeing if the substance brought condensation. We could have improved out

philosopher who pronounced the basic substance to be was air through condensations and rarefaction. He was also the first to pronounce the quality pairs hot/dry as well as cold/wet. Anaximenes would use the evidence that at any time air was in a certain area‚ it will become something different‚ such as being in rarefied‚ it turns into fire; if it was condensed‚ it became wind and as it was moving through different condensations‚ it will eventually be turning into clouds‚ water‚ earth and finally

a chain Polymers: a chain of many monomers that are chemically bonded together. How are polymers formed? Dehydration Synthesis (Condensation): two hydrogen atoms and one oxygen atom are removed from the monomers to form water‚ and the two monomers are joined together. How are polymers broken down? Hydrolysis—the reverse of dehydration synthesis (condensation) the reverse of dehydration synthesis. Water added to the polymer‚ unlinking the chain and breaking it back down to its original monomer

FUNDAMENTAL CONCEPTS Heat transfer is energy in transit‚ which occurs as a result of temperature gradient or difference. This temperature difference is thought of as a driving force that causes heat to flow. The concepts of heat transfer and temperature‚ the key words in the discipline of heat transfer‚ are 2 of the most basic concepts of thermodynamics. dffffffffff rifffff orfff ffffffffff fv ing ff ce Rate of transport process= fffffffffff or rate = coefficient B driving force resist

Lab # 25 2/15/12 Le Chatelier’s Principle Lab Purpose: To discover the effects of Le Chaterlier’s principle. Description: Chemical reactions can take place both forwards and backwards. When a reaction reacts to form products‚ some of the products react to form the reactants. In a chemical reaction‚ when the rate of a forward reaction equals the rate of a backward reaction‚ it is at equilibrium‚ where the products and reactants stay constant. If there is a change in condition on either reactants

Everything has matter. Matter makes up everything in the universe. Matter is anything that has volume or mass. I will be discussing the details of matter and other topics of science. All matter has all four general properties. They are mass‚ weight‚ volume‚ and density. The most important property of matter is mass. Mass is how much stuff‚ or matter‚ there is in any given object. Mass is the reason an object has‚ the second property‚ weight. When gravity pulls on an object it forms the weight. Weight
