“ Clean ” or unpolluted rain has an acidic pH, but usually no lower than 5. 7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid.

Further separation was carried out in the presence of a citric acid / ammonium buffer solution in a weakly acidic medium ( pH ≈ 3. 5 ), using ion exchange at elevated temperature.

The convention for a nucleic acid sequence is to list the nucleotides as they occur from the 5 ' end to the 3 ' end of the polymer chain, where 5 ' and 3 ' refer to the numbering of carbons around the ribose ring which participate in forming the phosphate diester linkages of the chain.

Thyroid hormones such as 3, 5, 3 ’- triiodothyronine ( T3 ) and 3, 5, 3 ’, 5 ’- tetraiodothyronine ( thyroxine, T4 ) make up a subset of this class because they derive from the combination of two iodinated tyrosine amino acid residues.

Larger amounts of radioactive material were later isolated from coral debris of the atoll, which were delivered to the U. S.

The number of successes on each shot is a value of a random variable that has values 0 or 1, and there are 5 such random variables here.

Now, in 1961, the Catholic population of England is still quite small ( ten per cent, or 5 million ) ; ;

The importance of this 5 can largely be explained by the natural mathematical properties of the middle number and its special relationship to all the rest of the numbers -- quite apart from any numerological considerations, which is to say, any symbolic meaning arbitrarily assigned to it.

If one takes the middle number, 5, and multiplies it by 3 ( the base number of the magic square of three ), the result is 15, which is also the constant sum of all the rows, columns, and two main diagonals.

Made of gold-plated britannium on a black metal base, it is 13. 5 in ( 34 cm ) tall, weighs 8. 5 lb ( 3. 85 kg ) and depicts a knight rendered in Art Deco style holding a crusader's sword standing on a reel of film with five spokes.
