Question

help please!!

7. Scientists like to use data to build physical models (or mathematical models to predict how data will look). Linear trends are easiest to work with; so we often look for ways to identify linear trends in a data set. Nuclear reactions all follow first order kinetics meaning the rate of a nuclear reaction is given by: rate = k[radioactive isotope) in which k is a first order rate constant. As shown in the kinetics portion of this course, this relationship can be transformed to the following Integrated rate law: In[radioactive isotope] =-kt + Infradioactive isotopelo in which in is a natural logarithm, t is time (represented by the Round number in your experiment). [radioactive isotope)o is the concentration at time zero (the number of Skittles you start with in this experiment) and (radioactive isotope), is the concentration of radioactive isotope at time t(number of remaining parent Skittles in this experiment). For each round in your experiment, calculate the natural log (In) of the number of daughter atoms. Enter the Round number and number of Daughter Atoms Produced (from Tables 1 and 2 in Question #2), and In(Daughter Atoms) in Table 3 below: Table 3: Round number vs. In(Daughter Atoms) Round Trial 1 Skittles "S" Down Producd (Daughter Atoms) In (Daughter Atoms) Round Trial 2 Skittles "S" Down Produed (Daughter Atoms) 0 (Daughter Atoms) 0 0 NO 2 W 600

yeah sorry here is an updated page

I need the In daughter atoms i don't know how to the calculations for it

Answer 1

In (Daughter atom) means we have to take natural log of daughter atom. In (saughter oben) - 2.303 logro (soughts aten) For this, we have to remember some log, values or se og tabela For example, log (35) = logro (5x7) = log 5 + log. 7 - Ö.7 + 0.85 = 1.55 Trial 1 Isial 2 Round Daughter Atom ln(saughter atom) Round Daughter Insaughter 28 3.55 2594 1.79 od mo I9 3.33 2.64 2.303_ 2.079 8

Answer 2

how did you get from 2.303?
