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.
Does a combustion reaction give off or absorb heat?
It's an exothermic reaction, which means it gives off heat.
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?
In perkin reaction we take aliphatic aldehydes the base readily reacts with aipha hydrogen and give major of the aldol product.
Which coupling give higher gain in case of amplifier?
Transformer coupling
Why amines give litmus paper test?
to test the acidity or alkalinity of a solution.
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

What is reversesible reaction?
reaction in which the products change back to give the reactants is called a reversible reaction.
