30M). Closer comparison that if you take the results obtained from trial one with trypsin at a salt concentration of 0.075M‚ the absorbance was 0.165 (440 nm wavelength). In comparison to 0.15M‚ which had an absorbency of 0.108 (440 nm wavelength). This would cause the enzyme to slow down and not work as effectively. Though the errors in the data would cause the hypothesis to be deemed inconclusive‚ the results obtained would lead to a rationale hypothesis that would be supported. It would not be

Hypothesis: The higher the concentration of hydrochloric acid‚ the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction. The lower the concentration‚ the weaker the reaction will be as there will be fewer particles so less chance of a collision and a lower rate of reaction. Equipment: Conical flask – to hold the hydrochloric acid and marble chips Boiling tube – to hold and indicate

Just because you have finished college two years earlier does not give you the right to tease your old schoolmates who are lagging behind. Or does it? While it is rude to act superciliously toward them‚ knowing that you made the better choice to challenge yourself is enough of a pride booster. Recently‚ high school pupils graduate high school with a number of college credits‚ whether from AP courses or from a dual enrollment program at a local college or university. If high school students are already

Heck’s Kitchens has excess capacity. Mr. Cifer wants the cabinets in cherry rather than oak‚ so direct material costs will increase by $50 per unit. CIfer wants to pay only a 20% markup. For Heck’s Kitchens‚ what is the minimum acceptable price of this one-time-only special order? Prepare an incremental analysis in good form. Minimum acceptable price = $455 + $300 + $45 + $50 = $850 Unit price = ($455 + $300 + $45 + $50)*120% = $1‚020 Total price of the order ($1‚020*60) $61‚200 Incremental

Introduction In today’s modern urbanized society‚ a heavy load of responsibility for child care is much needed‚ guiding them as they grow and especially focusing your attention towards them. When the family is good there is usually a stable emotional atmosphere in the home and a consistent method in bringing up the children. But in the other hand‚ based on observations‚ it have implied that when marital relations between the parents are poor (broken)‚ the child may be highly emotionally

Experiment 1 :Alkanes&Alkenes:Combustion and action of sulphuric acid. Introduction In the study of organic chemistry‚ the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. They can be gases as‚ propane‚ they can be liquids‚ for example‚ benzene‚ or they can be low-melting solids and waxes‚ for example‚ polystyrene. There are four classifications of hydrocarbons; saturated hydrocarbons or alkanes‚ unsaturated hydrocarbons or alkenes and alkynes‚ cycloalkanes‚ and

EXPERIMENT A: CIS-TRANS CONVERSION OF BUTENEDIOIC ACID PRE-LAB ASSIGNMENT 1. Maleic acid is the cis version and fumaric acis is the trans version of butenedioic acid. 2. 3. See attached paper. 4. Maleic anhydride is the compound that crystalizes in part A in the experiment. 5. HCl acts as a catalyst to break one of the carbonyl group in the maleic acid which rotates the structure to form a trans structure of the butonal acid which is the fumaric acid. And it does so by donating
