Compare Amy Tan's first two paragraphs with the rest of her essay. What do you observe about the sentence structure?

For each of the following sets of pressure/volume data, calculate the missing quantity after the change is made. Assume that the temperature and the amount of gas remain the same.
b. $V=331 \mathrm{~mL}$ at $1.08 \mathrm{~atm} ; V=299 \mathrm{~mL}$ at ? atm

$D_3$ is given by the group table below:

$$\begin{array}{|c|c|c|c|c|c|c|} * & e & r & s & x & y & z \\ \hline e & e & r & s & x & y & z \\ \hline r & r & s & e & z & x & y \\ \hline s & s & e & r & y & z & x \\ \hline x & x & y & z & e & r & s \\ \hline y & y & z & x & s & e & r \\ \hline z & z & x & y & r & s & e \\ \hline \end{array}$$

Group $\{A, \star\}$ is {0,4} under addition modulo 8 .

Function $f: D_3 \rightarrow A$ is a group homomorphism from $D_3$ to $A$. Find all possible kernels of f and explain why there can be no others.

A sample of a refrigeration gas in a volume of $455 \mathrm{~mL}$, at a pressure of $1.51$ atm and at a temperature of $25.0{ }^{\circ} \mathrm{C}$, was compressed into a volume of $222 \mathrm{~mL}$ with a pressure of $2.00 \mathrm{~atm}$. To what temperature (in ${ }^{\circ} \mathrm{C}$ ) did it have to change?

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement.
