dissolve the sample in KOH. Add AgNO3 and weigh the ppt. to obtain the halide content.

When you highlight it, be sure you did a cut or copy.  Try using "Ctrl + C" for copy, and "Ctrl + X" for cut.

SOrry, I can't help you. If I had the formulas I could do it, but there is no way I remember that off the top of my head! Good luck

Use the second derivative test, not sure exactly what it is still but it should be easy to find on the internet.

You need to measure the distance between the closely spaced lines (J values).  Trans and cis J values will be different

Go with a line graph, that way you can also find out (or estimate) temperatures at times when you didnt measure it.

use the equation  pH= -lgKa+ lg( salt/acid)\n(this equation only applies for buffer system)

omg i just had this test today too!!!!!\nu use hess's law to find the change--->write the equation, balance it \nand then use the moles (coefficients) to multiply the change is s for each element.\nhess's law says that the change in s (or h, or G, its usable for any of the thermo concepts) is equal to the sum of the entropy of the products minus the sum of the entropy of the reactants. its pretty easy after that--just plug in the values and there you go! \ngood luck! this was a hard test for me..so confusing.

tiny amounts of chemical can stick to differnt things, like stir bar, stir rod, thermometer and if you remove these items before the experiment is over then you remove some chemicals.  Other kinetics events that your not considering. as in pressure, humididtym and so on.  If you used a Ph probe then maybe it wasn't calibrated right or isn't properly maintained

There are a number of available tools in the following website:\n\nhttp://www.functionx.com/

There is Window Object which can be used to check the text copied to the Buffer.\nThe keyword through which you can get the text at buffer is  window.clipboardData.getData('Text').\n<script>\nfunction test(){\nvar t= window.clipboardData.getData('Text');\nif(t.length > 100)\n  alert("greater then 100 characters in your buffer");\nelse\n  alert("allowed to do whatever you want");\n}\n</script>\n\nUse this javascript onpaste method.Few more things you may have to do , as onpaste may not always .

It appears that the constants are calculated at one condition (dry,wet,etc) whereas the effective is closer to reality.  See\n\nhttp://www.pnas.org/cgi/content/full/102/45/16293
