Suppose 0.1g of iodine in 50cm3 of water is shaken with 25cm3 of ccl4 The distribution coefficient of iodine between water and ccl4 at ordinary temperature is 1/85 compute the weight of iodine remaining in the aqeous phase after 1 extraction with 25cm3 and after 3 extractions with 8.33cm3

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
