Do an iodoform test. Use an aqueous solution of iodine and potassium iodide added to basic solutions of 2-pentanone and 3-pentanone.
The iodoform reaction is a classical test for methyl ketones. A light-yellow precipitate of iodoform forms immediately with the methyl ketone of 2-pentanone.
To confirm:
1H NMR
3-pentanone will show only 2 signals: a triplet at ~1.33 and a quartet at ~2.35
2-pentanone will show 4 signals: a triplet at ~0.90, a sextet at ~1.55, a singlet at ~2.05 and a triplet at ~2.40
a test (such las the MMPI) developed by testing a pool of items and then selecting those that discriminate between groups
The 98 percent confidence level is commonly used in statistical tests. The critical Zc refers to the amount of relation between to factors.

There are many websites online that offer GRE practice tests, but many are not legitimate tests. For the best GRE practice tests, one should look into the Princeton Review. http://www.princetonreview.com/grad/free-gre-practice-test.aspx

To distinguish between pericarditis and a heart attack.
She could easily distinguish her sister's laughter from the rest of the crowd.

what are physical and chemical tests to differentiate between meat of dead animals and live slaughtered animals?
melting point will definitely distinguish them since the melting point of acetaminophen is about 169 - 172 and ibuprofen is 75-78. You can also do an NMR spectroscopy and count the number of protons that you see.
PCR testing should be used to distinguish between M.tuberculosis from other atypical non tuberculous mycobacteria.

It might, in a screen. More accurate tests can readily distinguish between hydrocodone and other opiates, though.
The best way to distinguish between sciatica and a neoplasm is through checking the erythrocyte sedimentation rate (Westergren Test) and use of appropriate imaging. Just performing a SLR will not distinguish between the two, as they will both have a positive test. Imaging studies are an essential part of the medical diagnosis, but even with these diagnostic tests, errors in conducting and interpreting imaging results may vary, symptoms may also result from involvement outside the area captured - which is why it is also important to run blood tests.
There are many different tests that can be used to identify different metals. Using a magnet is a popular test to distinguish metals.
