with water ethanol is soluble while methane is in soluble
Ionic compounds: conduct electricity, dissolve in water, are usually in lattice structures (crystal-like), is made from a metal and a non-metal. Covalent compounds: weak conduction of electricity if any, will not dissolve in water (not completely, anyway), are usually... not crystal-like (they're softer and squisher, usually), made from a non-metal and a non-metal.
in both the tests the main motto is to determine the inorganic metal contents.
Because sucrose is a complex disaccharide, it is not classified as either an aldose or a ketone. Instead, it is a compound that contains both. It can be easily broken down into its component aldose and ketonic molecules, either during digestion in the body, or through exposure to acids such as those present in lemon juice while cooking.Additionally, sucrose will fail tests such as Benedict's test, which are designed to detect aldose molecules present in its makeup. This is because of its unique, closed-chain type of molecular structure.
what are physical and chemical tests to differentiate between meat of dead animals and live slaughtered animals?
It depends on the type of tests.
Test(s) to differentiate between conditions. In medicine, to specifically diagnose a disease.
Making qualitative analytical chemistry tests.
Seliwanoff's test is used to differentiate aldose [glucose] from ketose [fructose]. Seliwanoff's reagent is composed of resorcinol and HCl. When heated with concentrated hydrochloric acid, the polysaccharides and oligosaccharides hydrolyze to yield monosaccharides. Then, resorcinol reacts in the dehydrated ketose to form oxymethylfurfurol produce a deep cherry red color [red precipitate]. Aldoses produces a faint pink colored solution.
PCR testing should be used to distinguish between M.tuberculosis from other atypical non tuberculous mycobacteria.

Show prejudice for or against (someone or something) unfairly: "the tests were biased against women"; "a biased view of the worldRecognize a distinction; differentiate.Perceive or constitute the difference in or between
Distinguish is similar in meaning to differentiate. An example would be, teachers use tests to distinguish between successful students and unsuccessful students.
The responses to projective tests are content analyzed for meaning rather than being based on presuppositions about meaning, as in the case with objective test.
Drug tests can not differentiate the means of taking a drug.
