HURRY PLEASE HELP Carbon-14 has a half-life of 5,770 years. A 25 gram sample of Carbon-14 was found. The original sample mass was hypothesized to have a mass of 100 grams.
How old was the sample based on this hypothesis?
A. 2885
B. 11,540
C. 17,310
D. 23,080

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

What conclusion can you draw from this experiment about the components of the black ink?

What would be the original temperature of a gas that has a volume of 2.0 l and a pressure of 2.0 atm and an unknown temperature that the volume increased to 3.5 l in its pressure decreased to 1.0 atm if the final temperature is measured to be 11°c
