1. Use the table above. Scientists find a piece of wood that is thought to be from an ancient fire circle. They find that the wood contains an amount of carbon-14 (14C) that is approximately 1/16 of the current atmospheric 14C levels. 14C has a t1/2 of 5,750 years. (5 pts)How many half lives is represented by 1/16? How many years ago was the tree chopped down to be used for firewood?If you started with 1,000,000 carbon-14 atoms, how many atoms would remain in the wood?
Please help, don't send some obscure link, thanks so much!

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
