Interpretation Introduction Interpretation: The mass and natural abundance of Si-30 is to be determined. Explanation Calculate the Si-28 fraction as follows: Fraction Si- 28 = 92.2 100 = 0.922 Calculate the Si-29 fraction as follows: Fraction Si- 29 = 4.67 100 = 0.0467 Calculate the Si-30 natural abundance as follows: Natural abundance = 100 % − ( Natural abundance Si- 28 + Natural abundance Si- 29 ) = 100 % − ( 92.2 % + 4.67 % ) = 3.13 % Calculate the Si-30 fraction as follows: Fraction isotope Si- 30 = 3.13 100 = 0

Q9. The insecticide DDT (in the box below) is useful in controlling mosquito populations and has low toxicity to humans, but is dangerous to birds and fish. Hoping to alleviate the dangers, little Johnny Whizbang, an aspiring chemist, proposes a new version of DDT ("Bromo-DDT") and shows his synthesis to his boss. Will Johnny Whizbang's synthesis work? Or will he be fired? Assume there is an excess of bromine and polybrominated products can be separated. Explain why. CH3 Br2, light CBR3 ok-ok Br Br Br Br CI "Bromo-DDT" CCl 3 DDT (dichlorodiphenyltrichloroethane) CI

Differentiate the terms Monotectic, Eutectic, Eutectoid, Peritectic, Peritectoid.
