How do you convert 389 K to Celsius?
You can use this equation to convert Kelvin to degrees Celsius: ºK - 273.15 = ºC
How do convert Kevin into Celsius?
Use this equation to convert Kelvin to degrees Celsius/Centigrade: [°C] = [K] - 273.15
What type of energy does the plant use to convert CO2 and H20 into sugar?
Plants use the energy from sunlight to convert co2 and h2o into glucose [sugar].
Use the conversion formula to convert 98.6 degrees Fahrenheit to degrees in celsius?
Use this equation to convert degrees Fahrenheit (ºF) to degrees Celsius/Centigrade (ºC): [°C] = ([°F] - 32) × 0.556
Why you use BaSO4 reagent instead of BaCl2 solution in limit test of sulphate?
BaSO4 is insolubel AND it contains sulfate, the ion of which the absence or existance should be tested for. (This doesn't sound quite logic)
To avoid carcinogenicity by the use of benzene to be chlorinated to become chlorobenzene could it be possible to convert far less toxic toluene to chlorobenzene?
No, it is impossible and useless, besides both chloro-methylbenzene (phenylchloride, as intermediate product) and chlorobenzene (final) are also carcinogenic
How do you convert aniline to phenol?
Use acetic anhydride as reagent. The reaction will undergo nucleophilic addition and the reagent will attach to the amine group. Half of the reagent will become the leaving group and one H of the amine group in the reactant will leave with the reagent. The product will be the benzene ring with an amine, carbonyl, methyl attached.
How do you convert chloro benzene to p-nitro phenol?
I'd do it this way. Use Dow's Process (NaOH) to convert chlorobenzene to phenol. Now, use nitrating mixture to get both o and p- nitrophenol. Fractional distillation should give you what you finally need.
What is the use of Diphenylamine reagent?
Ring-alkylated derivatives of diphenylamine are used as "antiozinates" in the manufacture of rubber products, reflecting the antioxidant nature of aniline derivatives. The compound undergoes various cyclisaton reactions. With sulfur, it gives phenothiazine, a precursor to certain pharmaceuticals.[
Which governmental agency mandates the use of PD Test prior to using aniline derivative tints?
Which governmental agency mandates the use of a P.D. Test prior to using aniline derivative tints?
Which governmental agency mandates the use of a PD Test prior to using aniline derivative tints?
Which governmental agency mandates the use of a P.D. Test prior to using aniline derivative tints?
Where use base?
1)they are use to form laboratory salt when combined with acid. 2)they are used to detect the chemical reagent. 3)they are use to manufacture many laboratory reagent.
What is the best way to obtain 5ml of liquid reagent from a large reagent bottle?
Use a pipette.
What is the use reagent bottle in science apparatus?
