(a) Why does xenon react with fluorine, whereas neon does not?
(b) Using reference sources such as the CRC Handbook of Chemistry and Physics or online sources, look up the bond lengths of Xe—F bonds in several molecules. How do these numbers compare to the radii of the elements?
Week four chapter 3 Naming oxyacids cont. Some acids have more than one ratio of hydrogen o Name according to the number of hydrogen present Ex: PO4-phosphate -2 HPO 4 hydrogen phosphate H2PO 4-dihydrogen phosphate H PO phosphoric acid 3 4 Molecular Mass or molecular weight, is the sum of the atomic masses in g/mol in a molecule o Mass of one SO 2olecule 1S 32.07 ₊ 20 16.00(2) ------------------- SO264.07 Chemical Formula Empirical- simplest Molecular- actual Ex: Formaldehyde- CH O Formula Mass 30g/mol 2 Finding Formula Ex: C17 21N4 C= 67.31% H=6.98% O=21.20% N= 4.62% (if given in percent, assume 100 grams) Step 1- convert grams to moles (by dividing given number by atomic mass) 67.31 =5.5998 H 6.98=6.9109 O 21.20=1.3250 N 4.62=.3298 12.02 1.01 16.00 14.01
