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.

Best Answer: Sodium chloride is composed of a metal and nonmetal so it is ionic. Both citric acid and sucrose are composed of C, H and O all nonmetals so these are covalently bonded.Nonmetals with other nonmetals are covalent because even the more electronegative element cannot completely pull the electrons off the second (or third) element so the result is electron sharing (a covalent bond).'m looking for either covalent or ionic bond and a short explanation as to why. I've also heard that sucrose is automatically covalent because all of its elements are nonmetals and would appreciate an explanation on that. Follow. 2 answers 2.
