Is it a chemical or physical reaction?
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
How does the evolution of gas occur in a chemical reaction give an example?
This is a sign of a chemical reaction.
What name is given to reaction which give out heat?
Such reactions are called Exothermic reactions.
Which aldehyde do not give fhelings test?
Aromatic aldehydes, such as benzaldehyde, typically do not give a positive Fehling's test due to the lack of alpha-hydrogens required for oxidation. Aromatic aldehydes are not easily oxidized in the Fehling's test compared to aliphatic aldehydes.
What is the difference between rate of reaction and chemical equation?
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
Why perkin reaction is not possible for aliphatic aldehyde?
The Perkin reaction typically involves the condensation of aromatic aldehydes with an acid anhydride in the presence of a base to form an α,β-unsaturated carboxylic acid. Aliphatic aldehydes lack the necessary stabilization of the intermediate enolate ion due to the absence of conjugation with an aromatic ring, making the Perkin reaction unfavorable for aliphatic aldehydes.
Which coupling give higher gain in case of amplifier?
Transformer coupling
How can you distinguish aniline and primary amine?
Aniline is a specific type of primary amine that contains a phenyl group attached to the amino group. One way to distinguish them is by performing a diazo coupling reaction, where aniline will give a colored dye, whereas a simple primary amine will not show this reaction. Additionally, aniline can be distinguished by its distinctive smell and the fact that it can undergo aromatic electrophilic substitution reactions due to the presence of the phenyl group.
What is saturated polyester resin?
Reaction product of reacting acid with alcohol to give an ester this is called polyester, saturated polyester is reaction product of saturated acid " may be aromatic dibasic acids like phthalic anhydride, isophthalic acid, terephthalic acid,etc.... or aliphatic aicds like adipic, sebacicl,....etc." with alcohol like " glycerol, pentaerythritol, trimethylol propane, neopentyl glycol, etc......." .

Why breather is not used in fluid coupling?
Breather is provided where the oil tends to give out fumes after getting heated. in a fluid coupling the fluid is not heated upto that temperature hence not required
Which coupling gives the higher gain in case of amplifier?
DC coupling on the input/output will always give higher gain because AC coupling involves inserting a capacitor, which adds impedance and augments the signal. AC coupling is sometimes necessary though, for such purposes as eliminating DC offset on the base of a transistor, or eliminating a DC offset in a single supply opamp circuit.
What is the meaning of look to this day and give an reaction?
It means the person is wanting to give reaction to the weather. He/She wants to give reaction about the day.
What is electro-technical coupling and please give an example of a product that uses it?
This is probably a homework or exam question.
What is a coupling?
couplings are used to join sections of long transmission shafts. couplings are also used to connect the shaft of a driving machine to the shaft of a separately built machine so as to give an effect of continuous shaft. the general classification of couplings is as given under: 1. rigid coupling 2. flexible coupling 3.Camlock coupling

Why amines give litmus paper test?
Amines have basic properties due to the lone pair of electrons on the nitrogen atom. When an amine reacts with the acidic components in litmus paper, it causes a color change, turning the paper blue and indicating the presence of a base or basic substance.
