Chemistry Final Study Guide Matter as anything that has mass and takes up space. Significant figures refers to digits that were measured. When rounding calculated numbers‚ we pay attention to significant figures so we do not overstate the accuracy of our answers. Rules: -All nonzero digits are significant. -Zeroes between two significant figures are themselves significant. -Zeroes at the beginning of a number are never significant. -Zeroes at the end of a number are significant if a decimal

knowledge of the time period in which “The Yellow Wallpaper” was written and the views of the time period. Roth‚ Marty. “Gilman ’s Arabesque Wallpaper.” Mosaic (Winnipeg) 34.1 (Dec. 2001): 145t. Questia. Web. 5 Apr. 2013. In Marty Roth’s analytical essay of The Yellow Wallpaper that wallpaper is “conceal[ing] dirt” and she also says that wallpaper is “the invention of laziness and filth” (Roth‚ 2‚3). In this instance the wallpaper is seen as a definite negative and can also be seen as symbolic of

final product‚ which is called ________. 6. For further derivation of energy‚ aerobic cells must convert pyruvate into acetyl coenzyme A by stripping off a C02 molecule. This process is known as ___________. 7. All of the reactions of glucose oxidation that follow glycolysis involving the transfer of electrons to their final acceptor‚ oxygen‚ take place in eukaryotic cells in the ___________. 8. Because the chemical formation of ATP is driven by a diffusion force similar to osmosis‚ this process

used COD as a source of organics for denitrification. In the next 2 hours of aeration‚ ammonium was oxidized faster than COD and reached 89%. This was a result of the increase in DO concentration that exceeded 6 mg/L. The increase in DO made the oxidation of NH4-N unlimited. The first-order kinetic constants were 0.34 h-1 and 0.24 h-1 (Table 6)‚ with correlation coefficients of 0.94 and

Malunggay Malunggay leaves was once considered a "poor man’s vegetables" but now it is known as a "miracle tree" or "nature’s medicine cabinet" by scientists and health care workers from around the world because it is loaded with vitamins and minerals that can be an effective remedy against many kinds of ailments. All parts of the malunggay tree are usable for nutritional and medicinal purposes

Determining activation energy (Ea) of a reaction © KCl http://hk.geocities.com/fatherofchemistry Objective To determine the activation energy for the reduction of peroxodisulphate(VI) ions. S2O82-‚ by iodide ions I-‚ using a ’clock’ reaction. Principle The equation for reduction of S2O82- by I- is: S2O82- + 2I- → 2SO42- + I2 The formation of iodine is ’monitored’ by small & known amount of thiosulphate ions‚ S2O32-:

n this lab‚ everyone got a flask which we then drew a pumpkin face on. Then we mixed 42 mL sodium hydroxide solution‚ 10 g of glucose‚ 1 mL‚ 1 L of water and Methylene blue solution and leave it undisturbed. The blue solution turned clear and when we added the yellow food coloring it turned an orange color. The solution then turned dark blue once the solution was shaken vigorously. This reaction occurred because the oxygen oxidized the methylene blue.In the oxidized state the methylene blue shows

• The reactions of the citric acid cycle include two other oxidative decarboxylation‚ which transform citrate into succinate. • The cycle is complete by regenaration of oxaloacetate from succinate in a multistep process that includes two other oxidation reactions. Pyruvate + 4NAD+ + FAD + GDP + Pi + 2H2O 3CO2 + 4NADH + FADH2 + GTP + 4H+ • The cycle is strongly exergonic. Pyruvate is Converted to Acetyl-CoA Pyruvate dehydrogenase complex is responsible for the conversion of pyruvate

Many hair dye components such as‚ pphenylenediamine‚ 2‚5diaminotoluene‚ and 2‚5diaminoanisole become strongly mutagenic after oxidation by H2O2 gives a very strong mutagenic response with strain when sulfur is present‚ which is located in the hair. As mentioned before‚ it can be hard to know what the results of these studies mean‚ due to many other factors that might affect the
