There are 5 xx 10^21 atoms in a object of 1 g. If one electron is removed from 0.01% atom, what will be the charge on the sphere ?

The key feature of Bohr's spectrum of hydrogen atom is the quantization of angular momentum when an electron is revolving around a proton. We will extend this to a general rotational motion to find quantized rotational energy of a diatomic molecule assuming it to be rigid.The rule to be applied is Bohr's quantization condition. it is found that the excitation from ground to the first excited state of rotation for the CO molecule is close to (4)/(pi) xx 10^(11) Hz then the moment of inertia of CO molecule about its center of mass is close to (Take h = 2 pi xx 10^(-34) J s )

An electron in an atom is revolving round the nucleus in a circular orbit of radius 5.3 xx 10^(-11) m, with a speed of 2 xx 10^(6) ms^(-1) .

Chemical reactions involve interation of atoms and molecules. A large number of atoms // molecules ( approximately 6.023xx10^(23)) are present in a few grams of any chemical compound varying with their atomic // molecular masses. To handle such large numbers conveniently, the mole concept was introduced. This concept has implications in diverse areas such as analytical chemistry, biochemistry, electrochemistry, and radiochemistry. The following example illustrates a typical case, involving chemical // electrochemical reaction, which requires a clear understanding of the mole concept. A 4.0M aqueous solution of NaCl is prepared and 500mL of this solution is electrolyzed. This leads to the evolution of chlorine gas at one of the electrodes ( atomic mass of Na is 23 and Hg is 200)(1F=96500C) . The total number of moles of chlorine gas evolved is

A magnetic dipole is under the influence of two magnetic fields. The angle between the field directions is 60°, and one of the fields has a magnitude of 1.2 xx 10^(-2) T. If the dipole comes to stable equilibrium at an angle of 15° with this field, what is the magnitude of the other field?

During Searle's experiment, zero of the Vernier sacle lies between 3.20 xx 10^(-2), and 3.25 xx 10^(-2)m of the main scale. The 20^(th) division of the Vernier scale exactly coincides with one of the main scale divisions. When an additional load of 2kg is applied to the wire, the zero of the vernier scale still lies between 3.20 xx 10^(-2), and 3.25 xx 10^(-2)m of the main scale but now the 45^(th) division of Vernier scale coincide with one of the main scale divisions. the length of the thin metallic wire is 2m and its cross-sectional ares is 8 xx 10^(-7)m^(2) . the least count of the Vernier scale is 1.0 xx 10^(-5)m . the maximum percentage error in the Young's modulus of the wire is
