Chapter 1

1.45
Solution manual states Δv = 5.0 m.s-1
Velocity was given as 5.00 ± 5.0 m.s-1
Therefore Δv = 10.0 m.s-1
With the correction, the final answer is: Δx = 6.7 x 10-37 m

Asks to list the ionic radius in increasing order.
The solution manual puts it in decreasing order.
Error: P3- > S2- > Cl-
Correction: Cl- < S2- < P3-

In the picture, it shows A (smaller atom) + B (larger atom) --> C (larger ion) + D (smaller ion)

The solution manual says that A=Na and B=Cl, and it references Figure 2.20 which explicitly
lists the atomic radius of Na to be 154 pm and the atomic radius of Cl to be 99 pm.

It also says that C=Na+ and D=Cl-, referencing Figure 2.22 which shows that the ionic radius
of Na+ to be 102 pm and the ionic radius of Cl- to be 181 pm.

Error: A=Na; B=Cl; C=Na+; D=Cl-
Correction: A=Cl ; B=Na; C=Cl-; D=Na+

First calculate the decrease in entropy resulting from the decrease in volume. Then calculate
the increase in entropy resulting from the increase in temperature. Then add these to get the
net entropy change. Assume ideal behavior and 1 mol N2 gas.
