Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

Procedure: The first part of this lab involved the standardization of the base NaOH with potassium hydrogen phthalate‚ or KHP. First‚ about 400 mL of NaOH (10 M) were poured into the 600-mL beaker. This was used to fill the burette. The 50-mL burette was rinsed through twice with 5 mL of NaOH. Then‚ the burette was mounted on the ring stand using a burette clamp and filled to 0 mL. Some of the NaOH was drained to fill the tip of the burette. The initial volume of NaOH‚ rounded to two decimal places

Biology investigation: Liver and hydrogen peroxide By Cuong Tran Abstract: The purpose of this investigation was to determine the optimum temperature for enzyme activity. The stated hypothesis was that 37oC would be the optimum temperature for liver enzymes to break down hydrogen peroxide into water and oxygen. The dependent variable was to measure the amount of foam being produced‚ while testing 4 different temperatures with 3 repetitions each. Out of the 12 trials only 2 outliers were found

the R Lab 1. One mole of hydrogen gas has a mass of 2.02 g. Use your value of molar volume to calculate the mass of one Liter of hydrogen gas at STP. The density is in g/L. Compare your value to a literature value? (Consult a hand book or text book) 2. In setting up this experiment‚ a student noticed that a bubble of air leaked into the gas tube when it was inverted in the water bath. What effect would this have on the measured volume of hydrogen gas? Would the calculate value
