3) You're wandering around and come upon an interesting looking rock. The rock is slightly radioactive, so you analyze it. The resulting data is as follows: Elapsed Time (s) Counts 962 50 891 100 718 150 598 200 531 250 448 300 413 350 334 400 308 450 287 500 202 550 178 600 154 a. Calculate the value of k using any two of the above data points. b. Use your value of k to determine the half-life of this sample.

ical reactions. It 18 not true, however that the fourth postulate is be nuclear reactions. Dalton believed that atoms were solid, indivisible spheres, an idea we now reje But he showed remarkable insight into the nature of matter and its interactions. Sone of his ideas could not be verified (or refuted) experimentally at the timne. They were based on the limited experimental observations of his day. Even with their shortcomings Dalton's ideas provided a framework that could be modified and expanded by late scientists. Thus, John Dalton is often considered to be the father of modern atomie theary. In Dalton's work, he thought that atoms are indestruetible. However, it was later found that atoms still contain smaller particles and that these subatomic particles further contain particles within them. Since then, sorne revisions have been made on Dalton's work although much of il renained intact. What's More BC Independent Activity 1. Sum it up Complete the lable. Write the answer on the…

A certain drug has a half-life in the body of 2.0 h. Suppose a patient takes one 100. mg pill at 7:00PM and another identical pill 90 min later. Calculate the amount of drug left in his body at 11:00PM. Be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits.

Plot your values of In(Ksp) VS. 1/Tand find the slope and y-intercept of the best fit line. Use the equation for the best fit line and the following equation In(K) = - AH° RT AS° R to calculate AH and AS for dissolving Borax What is the slope of your best fit line in the plot? What is AH (kJ/mol)? What is the y-intercept of your best fit line in the plot? What is AS (J/mol)?

You are working for SETI, the Search for Extraterrestrial Intelligence. One day, you receive a radio communication from an alien intelligence. Although you cannot understand their language, they have included some photos from an ILove Lucy episode. The photos allow you to determine that it is the episode in which Lucy makes a television commercial on Vitameatavegamin. This episode first aired on CBS on May 5, 1952. Before running to your supervisor to tell him the news, you quickly determine how far away in light-years the alien civilization is.
