Find the final concentration of NO3- in a solution made by combining 0.954 L of 0.140 M Al(NO3)3 with 0.652 L of 0.430M LiNO3. A) 0.026 M B) 0.052 M C) 0.160 M D) 0.320 M E) 0.639 M

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.
