candle burned faster but they both burned at the same speed rate so it doesn’t really matter too much. Other brands could change the effect of the burn rate than other brands that are out there and they may also be made differently. There are more than one wax and that might change the burn rate of the candles. Some waxes may last longer than others. One thing that can be change the candle scents and see if that has any effect on the burning rate of the candle. There were no flaws in this experiment but

factors that can influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that can affect the rate of this diffusion. Our intent

Effects of SO2 On Fermentation Rates Purpose SO2 is the primary inhibitor for natural microbiological growth in wine. It prevents the browning of juice by inhibiting phenol oxidase activity and kills the natural yeast cells for the utilization of fermentation-controlled commercial Saccharomyce strands (Boulton et al. 1996). SO2 is pH and temperature dependent and can exist as several forms. The bisulfate form (HSO3-) can complex with soluble solids such as anthocyanins and acetaldehydes to become

The Population Growth Rate in India For many years concern has been voiced over the seemingly unchecked rate of population growth in India‚ but the most recent indications are that some success is being achieved in slowing the rate of population growth. The progress which has been achieved to date is still only of a modest nature and should not serve as premature cause for complacency. Moreover‚ a slowing of the rate of population growth is not incompatible with a dangerous population increase

initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

China has announced in 2005 the “end of its firm peg against the dollar‚ instead allowing it to trade within a narrow band against a basket of currencies.” China regime is managed floating system where the currency increases very slowly year by year and the China government prevent the currency from changing quickly in the short term. The reason why Chinese government intervene in the currency market is to lower exchange rate to increase employment‚ maintain a fixed rate to maintain

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over
