Assume all temperatures to be exact, and neglect significant
figures for small changes in dimension.
A diver releases an air bubble of volume 4.0 cm3 from a depth
of 17 m below the surface of a lake, where the temperature is 9.0
∘C.
What is the volume of the bubble when it reaches just below
the surface of the lake, where the temperature is 20 ∘C?
V = _____ cm^3

For this question you must give all answers
rounded correct to exactly 3 significant figures
(instead of decimal places). Recall that leading zeros are not
significant (for example 0.0011 has 4 decimal places, but only 2
significant figures). To obtain more decimal places in the numbers
Matlab gives you, type "format short g" first.

Answer the following questions based on the reaction below.
Report all answers to three significant figures.
K2SO4(aq) +
Sr(NO3)2(aq) → SrSO4(s) +
2KNO3(aq)
The concentration of K2SO4 is 0.222 M at the
start of the reaction, and 0.135 M after 122 seconds. The initial
concentrations of the products are zero.
1. What is the average rate of reaction (in M/min) over this time
period?
2. What is the average rate of
change (in M/min) of K2SO4 in the first 122...
