The Moment Of Inertia Of A Body Is Independent Of The moment of inertia of a body is independent of its angular velocity. It depends upon the position and orientation of the axis of rotation,shape and size of the body and distribution of mass of the body about the axis of rotation.
What is the Valency of Bromine? Valency is defined as the combined power of an element and is determined by the number of valence electrons in the outermost shell of an element. Bromine is an element that belongs to the halogen family with atomic number 35. Bromine has 7 valence electrons and the valency of … Read more
What Are Electrophiles And Nucleophiles? Explain With Examples 1. An electrophile is a reagent that takes away an electron pair. In other words, an electron-seeking reagent is called an electrophile (E+). 2. Electrophiles are electron deficient and can receive an electron pair. 3. Carbocations and neutral molecules having functional groups such as the carbonyl group … Read more
H2O2 can be obtained when the following reacts with H2SO4 except with (a) BaO2 (b) PbO2 (c) Na2O2 (d) SrO2 Correct option (b) PbO 2 Explanation: H 2 O 2 is prepared by the reaction of peroxide with H 2 SO 4 . PbO 2 is a dioxide. Hence, it does not give H 2 … Read more
In A Semiconductor, Current Conduction Is Due In a semiconductor, current conduction is due to both holes and electrons. In p-type materials, holes outnumber the free electrons and they are the majority carriers whereas, in N-type, free electrons are the majority carriers.
What happens when methyl chloride is treated with KCN? When methyl chloride is treated with KCN, it undergoes a substitution reaction to give methyl cyanide.
Species Diversity Decreases As We Move Away From The Equator Towards The Poles. What Could Be The Possible Reasons? Species diversity decreases as we move from the equator towards the poles because sunlight is less visible due to slanting rays of the sun but the equator possesses straight rays of sunlight due to which vegetation … Read more
