Percent of C-14 remaining in sample: 50%
Half-life of C-14:
5,730
Age estimate in years before present:
years old
You've just tested another sample, from an archaeological site.
Calculate the age of the sample. Hint: You can calculate the age by
multiplying the half-life of C-14 by the number of half-lives that have passed

What is the molar mass of a gas that has density of 2.054 g/l

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
