Scientists believe that ancient bacteria represents the first evidence of life on earth. which of these best describes the process by which bacteria was created?

decomposition of fungi
reactions in ancient plants
transformation of virus like molecules
reproduction in single celled organisms

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
