Determining the sound level
Sound level within the church (1 m away from the chorus) while people are singing is around 100 dB (0.01 W/m^2). Suppose sound waves are released equally in all directions. Determine the sound level (in dB) 1 km away from church.

A sample which is having 1.547-g of blue copper (II) sulfate penta hydrate, CuSO4 * 5 H2O is heated carefully to drive off the water. The white crystals of CuSO4 that are left behind have a mass of 0.989 g.
2,3-Dimethyl-2,3-butanediol (pinacol), upon heating in aqueous acid, rearranges to form 3,3-dimethyl-2-butanone(pinacolone). Suggest a mechanism for this reaction.
Identify these compounds and give each a suitable name. When 1-octene is treated with NBS, three monobromo straight-chain alkenes having molecular formula C9H17Br are isolated from the reaction mixture.
Write down the equations to show nitronium ions might be produced using a mixture of nitric acid and sulfuric acids.Explain which ring of phenyl benzoate you would expect to undergo nitration more readily.
Determine the molarity of a solution of 10% by the mass cadmium sulfate, CdSO4 (molar mass = 208.46g/mol) by mass when the density of the solution is 1.10g/ml.
The mass of the particle is around 6.64 x 10-27 kg. The particle employed in a scattering experiment consists of a kinetic energy of 7.30 x 10-13 J. Determine the de Broglie wavelength of the particle?
Discuss how photochemical isomerization allows the production of the thermodynamically less stable cis isomer. Explain why is the trans isomer exclusively converted to the cis isomer during short reaction periods and not vice Versa?
