Use three test tubes, put equal amout of enzymes in all and put the substance they digest in both (equal amounts of course).\n\ntake a test tube(A) and put 2cm3 of Hydrochloric acid.\nTake test tube (B) and put 2cm3 of Pure water(pH7).\nTake test tube (C) and put 2cm3 of Sodium Hydroxide.\n\nshake them all a little just as you start the test.\n\nLeave them for half an hour at their optimum temperature and other factors.Make sure all factors among them are equal.\n\nAfter that, Test for the substance you put in (e.g test for starch using iodine if you put starch in).\n\nThe one with the most negative result is the optimum pH.

an experiment is used to test a hypothesis.  \nhypothesis: i think that if i drop my pencil, it will stop when it hits the ground.\nexperiment: drop your pencil.\n\nif it stops when it hits the ground, you have proven your hypothesis.  if it goes through the ground, you had better find some wings fast, becuase the you are about to fall a very long way, or else you are dreaming ;)

Diffusion of a Dye in Hot and Cold Water\n\nPurpose:  The purpose of this experiment is to demonstrate the principle of diffusion.  Diffusion is the net movement of particles (atoms, ions, or molecules) from an area of greater concentration to areas of lesser concentration.\n\nMaterials and Methods:  For this experiment, the student will require a projector, two petri dishes, two 150 ml beakers, hot plate, potassium permanganate (purple dye), and a spatula.  Obtain about 50 ml of cold water in one beaker and about 50 ml or boiling water in the other.  Place the petri dishes on the projector and add cold water to one dish and boiling water to the other.  Allow the water in the dishes to become still.  Using the spatula, add a crystal of potassium permanganate to the center of each dish\n\nExperiment:  Observe the experiment for several minutes and note what happens to the purple dye in each petri dish.\n\nConclusion:  Do you observe diffusion in each?\n\nHow does the rate of diffusion differ? \n\nWhy is there a greater rate of diffusion in one

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask.  It is done by using the principles of the kinetic theory of matter.  \nAnother cool project might be doing something with dry ice.  Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions.  Make some dye molecules or something.\n\nHope one of these ideas works for you.

I am not quite sure what the question is. What should the manufacturer do? Did they already do the experiments or do you want to know what sort of experiments to do? Do you want to know how to reduce the data? How to present the data? What statistical tools might be useful?

Here are some activities that come to mind:\nPre-install: Self preparation: (understand how instrument works, what it needs, what install/operate/ESD procedures are).\nSite preparation (space, electricity, any other needed utilities like cooling water, etc.). Equipment preparation (unpack, assemble, test with temporary utility hookup).\nInstall: Attach/bolt down if necessary, permanent hookup to utilities, test and calibrate.\nESD: Powerdown sequence, increase or decrease cooling, plus normal shutdown stuff like stow sensors, remove test materials, cleanup.

Is this a lab exercise?

One of the best current techniques is called Design of Experiments (DOE).  There are numerous software packages to assist in proper design and give you the results.  The design consists of determining the number of variables and the levels of each variable you want to test.  You must also decide how many samples of each variable set you want to check.  For the first experiment keep the number of variables and the number of levels of each variable to a minimum.\n\nFor example:  If you want to determine the best way bake a pizza,  you may select oven temperature, bake time, and position in the oven.  If you decided to test two levels of each of these variables ( 400 & 450 degrees, 12 & 15 minutes, lower and upper rack position). For a full experiment, you would have to bake 8 pizzas.  If you wanted to bake 2 of each combination, to gain confidence in the results, you would have to bake 16 pizzas.\n\nIf you wanted to test three levels of each variable, the number would jump to 27 pizzas and 54 pizzas, which would be vey costly.  Keep the experiment simple and use the same brand/type pizza for each combination.\n\nYou may get great results with more than one combination, that's good.  If you get the same results with many combinations, you will have to redesign your experiment to widen the levels or pick a different variable to test.\n\nHope this helps.

Assuming a pure substance, (this method will not work on mixtures).  \n1. Dissolve in Carbon disulphide.  (The compound is now banned in schools)\n2. Allow to evaporate in a fume cupboard.\n3. The presence of yellow rhombic like crystals is a test for S.\n4. Melt a sample and do a MP test.\n5. Melt a few grammes and allow to cool in air.  Needle like crystals will be formed.

See comment above.\n\nYou do need to do several trials at various concentrations though. You can then determine it through a linear regression.\n\nI also suggest that you consult a book on Analytical chemistry, because Beer's law has limitations. For example, it loses linearity at higher concentrations.

1) Design - determine what the program will accomplish\n\n  2) Code - Write the necessary code to satisfy the design.\n\n  3) Test - Test the implementation of the design\n\n  4) Debug - Fix the problems encountered in step 3 because Steps 1 or 2 were done poorly.

1. Identify the problem. \n\n2. Refer to as many sources as possible.\n\n3. Ask an appropriate question. \n\n4. Develop a hypothesis.\n\n5. Do the experiment.\n\n6. Keep good records of the methods and results.\n\n7. Report the experiment.\n\n8. Analyze the results.\n\n9. Develop a conclusion.

What is the experiment?\n\nWhat were ALL the reagents?\n\nAs it stands, your question is unanswerable; it is like me asking you what is on my kitchen table.
