6. 7. 8. The reaction of sulphur in alkaline medium is given below Sais) +aOH bs2 (aq) (aq) + CS0 (aq) + H2O (1) . (Integer answer) The values of 'a' is 4.5g of compound A (MW = 90) was used to make 250 mL of its aqueous solution. The molarity of the solution in M is x 10. The value of x is (Rounded off to the nearest integer) A proton and a Li+ nucleus are accelerated by the same potential. If and p denote the de Brogle wavelength of Li+ and proton respectively, then the value of is xx10. The value of x up is 9. 10. (Rounded off to the nearest integer) [Mass of Li+= 8.3 mass of proton] The coordination number of an atom in a body-centred cubic structure is [Assume that the lattice is made up of atoms] Gaseous cyclobutene isomerizes to butadiene in a first order process which has 'k' value of 3.3 10 at 153C. The time in minutes it takes for the isomerization to proceed 40% to completion at this temperature is (Rounded off the nearest integer)
