Find the heat produced when a current of 0.5 A is passed through a coil of resistance 200Ω for 5 minutes * |
|
Answer» GIVEN :- I = 0.5A R = 200ohm TIME = 5min =5×60 = 300seconds now we need to find heat produced in coil.. using joule's law of HEATING..according to joule's law of heating given by the formula H = I²Rt it is clear that..heat produced in a conductor is directly proportional to :- i) square of CURRENT (I) ii) resistance of conductor (R) iii) time(t) for which current is passed now come to our question so by using formula H = I²Rt hence, heat producing in the coil is 15,000 joule |

Tetra ammonium iodide is a quaternary salt PRODUCED from the ammonolysis of an alkyl HALIDE with ammonia as the nucleophile. An alkyl or benzyl halide on reaction with an ethanolic SOLUTION of ammonia undergoes nucleophilic substitution reaction in which the halogen atom is replaced by an amino (–NH 2
) group. The primary amine thus obtained behaves as a nucleophile and can further react with an alkyl halide to FORM secondary and tertiary amines and finally quaternary ammonium salt. |

|
Answer» ong>Answer: Döbereiner's triads were an early attempt to SORT the elements into some logical order by their physical properties. It was discovered by reported Johann Wolfgang Döbereiner's in 1817.He also NOTED that quantifiable properties of elements (e.g. atomic weight and density) in a triad FOLLOWED a trend whereby the value of the middle element in the triad would be exactly or nearly predicted by taking the ARITHMETIC mean of values for that PROPERTY of the other two elements. |
