To determine whether nitrogen (N), phosphorus (P), and arsenic (As) form a Dobereiner's triad, we need to follow these steps: ### Step 1: Understand Dobereiner's Triad Dobereiner's triad is a concept in chemistry where three elements with similar properties are grouped together. The atomic mass of the middle element should be approximately equal to the arithmetic mean of the atomic masses of the other two elements. ### Step 2: Identify the Atomic Masses - Nitrogen (N) = 14.0 u - Phosphorus (P) = 31.0 u ...

    ._(15)P^(32) is beta active and has a short half life of 14 days. The ._(16)S^(12) nucleus produced is in ground state. On and average the emitted beta particles have 50% of the energy released in the reaction, remaining energy being carried by antineutrino. A liquid has small amount amount of P in it and it was found taht the liquid was receiving heat at a rate of about found that the liquid was receiving heat at a rate of about 10mW due to decay of P^(32) . It is to be noted that antineutrino do not intereact with matter easily and it would be safe to assume that they escape out of the contaienr. Estimate the number of P^(32) atom in the liquid. Relavent masses are P^(32):31.9740u S^(32):31.9720u e:0.0005u 1"day"=86400 s 1u=(931MeV)/(c^(2))

    The table shows the melting points and boiling points of six elements P, Q, R, S, T and U. These elements represent consecutive members of periods 3 and 4 of the periodic table. 0.2 mol of the chloride of element U reacts with excess of silver nitrate to form 57.4 g of silver chloride. The formula of chloride is (Given : Atomic mass of N = 14 u, O = 16 u, CI = 35.5 u, Ag = 108 u)

    A particle of unit mass is moving along the x-axis under the influence of a force and its total energy is conserved. Four possible forms of the potential energy of the particle are given in column-I (a and U0 are constants). Match the potential energies in column-I to the corresponding statement(s) in column-II. {:((A),U_1(x)= (U_0)/(2)[1-(x/a)^(2)]^(2),(P),"the force acting on the particle is zero at x = a."),((B),U_2(x)= (U_0)/(2)(x/a)^(2),(Q),"the force acting on the particle is zero at x = 0."),((C),U_2(x)= (U_0)/(2)(x/a)^(2)exp[-(x/a)],(R),"the force acting on the particle is zero at x = 0."),((D),U_4(x)= (U_0)/(2)[x/a - 1/3 (x/a)^3],(S),"The particle experiences an attractive force towards x = 0 in the region | x | < a"),(,,(T),"The particle with total energy" (U_0)/4 " can oscillate about the point"x = -a.):}

    A particle of mass m is located in a spherically symmetrical potential well U(r )=0 for r lt r_(0) and U(r )=U_(0) for r gt r_(0) . (a) By means of the substitution Psi(r )= xi(r )//r find the equation defining the proper values of energy E of the particle for E lt U_(0) , when its motion is described by a wave function Psi(r ) depending only on r .

    The uranium ore mined today contains only 0.72% of fissionable ""^(235)U , too little to make reactor fuel for thermal-neutron fission. For this reason, the mined ore must be enriched with ""^(235)U . Both ""^(235)U (T_(1//2) = 7.0 xx 10% y) and ""^(235)U (T_(1//2) = 4.5 xx 10^(9) y) are radioactive. How far back in time would natural uranium ore have been a practical reactor fuel, with a ""^(235)U//""^(235)U ratio of 3.0% ?
