Beginning with When You Are Old by William Butler Yeats‚ we as the reader’s first notice the rhyme scheme used. Readers observe that the first and fourth lines of the poem rhyme‚ as well as the second and third lines. Correspondingly‚ the poem grasps an iambic pentameter which gives Yeats poem a more musical characteristic. The word “And” appears in this poem more than six times just in the first stanza alone which keeps the rhythm of the meter constant. In my opinion‚ I believe that the narrator

essential that the structure is derived. Firstly it is important to determine the percentage composition of elements to work out the empirical formula. The empirical formula was found to be C10H12O and the mass of the unknown was 148.09 m/z which when calculating the molecular weight of the empirical formula it did equal 148.09 g mol -1. This means that the empirical formula is also the molecular formula. As 12.01x10 carbons +1.008x12 hydrogens + 16= 148.09 09 g mol -1. From this knowledge the unknown
