The entropy change on vaporization Delta S_{vap} of a compound or element is: (a) Always positive. (b) Always negative. (c) Sometimes is positive and sometimes is negative. Which of the following equations shows the greatest increase in entropy? Explain reasoning or show work. A) SO3(g...
In this article, I'll take an in-depth look at the components of a successful AP Chemistry syllabus, including content coverage, lab work, and overall curriculum requirements.I'll also give an example of a full syllabus (based on a sample from the College Board) and provide some helpful t...
Calculate the moles of NaOH(s) added to the calorimeter. A 3.50-gram sample of CH4 is burned in a calorimeter. The calorimeter is filled with 35.0 grams of water with a specific heat of 4.184 J/gC. The temperature of the calorimeter increases from 25.0 C to 30.0 C. Calculate the ...
Our work and that of others has been based on this premise, yet success has been elusive. Why do immunogens containing the 2F5 recognition sequence fail to induce a 2F5-like response? One possibility has already been discussed in the context of structural considerations. MAb 2F5 is broadly ...
The titre value of 0.01 M NaOH solution, which was titrated against an aliquot of rumen fluid containing VFAs was used in the equation: 1 ml of 0.01 M NaOH = 0.01 mmoles of VFA, to derive the concentrations of total VFA expressed in millimoles per litre of rumen fluid. Also, the ...
What is the final concentration of a 0.6 M NaCl solution if its volume is doubled and the number of moles of solute is tripled? Dissolution of which salt in water results in a decrease in the temperature of the solution? The Ksp of La(IO3)3 is 6.2*10^-12. What is the molar...
If 10^{3} moles of the herbicide NaAsO_2 (sodium arsenite) are added to 1 liter of distilled water a Some indoor air-purification systems work by converting a little of the oxygen in the air to ozone, which oxidizes mold and mildew spores a...

respectively. This amounts to an average daily intake of 0.56 mmoles of creatine by the CrMD rats and 0.61 mmoles of CLL by the CLLD group. For the last two days of the feeding period the rats consumed an average of 0.55 moles of creatine per day in the CrMD group and 0.59 mmoles...
