At the Family Tree DNA Conference in November, James Irvine and Maurice Gleeson both presented sessions on utilizing a combination of STR and SNP data and various tools in analyzing their individual projects. Mauriceâs presentation was titled âCombining SNPs, STRs and Genealogy to build a Surname Origins Tree.â.
SO4 (2-) is a sulfate anion, and it has sulfur-oxygen single bonds. These single bonds are shorter than normal sulfur-oxygen single bonds but longer than a sulfur-oxygen carbon bond. This phenomenon is called resonance. C) SF6 has entirely covalent sulfur-fluorine bonds and is octahedral.D) CaI2 is an ionic compound, with the calcium and iodide ions in a lattice structure.O4 (2-) is a sulfate anion, and it has sulfur-oxygen single bonds.

The answer is B. And the reason is that Compounds with any ionic bond are NOT molecules. 1  In \(H_2O\), Oxygen atom \(O\) has two different single covalent bonds with Hydrogen atoms (\(H-O-H\)). 2  In \(CO_2\), Carbon atom \(C\) has two different double covalent bonds with Oxygen atoms (\(O=C=O\)).
