Chapter 3, Problem 108E
A 25.0-mL sample of ethanol (density = 0.789g/mL) initially at 7.0°C is mixed with 35.0 mL of water (density =1.0g/mL) initially at 25.3°C in an insulated beaker. Assuming that no heat is lost, what is the final temperature of the mixture?

Technetium is the first element in the periodic chart that does not have any stable isotopes.
Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half
life ideally suited for medical tests. It would seem that the decay of technetium should fit the
treatment above with the result In(c/c) = -kt. The table below includes data from the two sites:

a.
b.
C.
Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also
graph In(c/c.) on the vertical axis versus time on the horizontal axis.
When half of the original amount of starting material has hours fraction remaining
disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes
In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the
material to decay away). Determine the slope of your In(c/c.) vs
t graph and…
