C-14 analysis of the Shroud of Turin has shown that approximately 93% of the 14C present in living matter is still present in samples taken from the shroud. Based on this information, what is the approximate age of this relic? Were the Shroud to date to 33 CE, what would be the anticipated fraction of 14C present today relative to the amount originally present
Explain while carbon is bonded to 4 hydrogen atoms to form CH4, the 2s and the three 2p orbitals undergo hybridization to form four sp3 orbitals. By hybridization of the carbon atom, a total of four lone electron orbital sites are established. The..
