For practice in counting microstates, determine how many ways there are to arrange three quanta among four one-dimensional oscillators. (This would represent one-and-a-hird atoms, so this doesn't make physical sense.)

Make a stem-and-leaf plot and a box-and-whisker plot of the following data, which represent the heights, in inches, of students in an eleventh-grade chemistry class.

61, 80, 63, 72, 79, 63, 72, 76, 69, 67, 65, 66,

71, 65, 73, 72, 65, 70, 64, 73, 66, 68, 70, 71, 72

Concentration of a Mixture A $1000$-liter tank contains $50$ liters of a $25$ brine solution. You add $x$ liters of a $75$ brine solution to the tank.

(b) Determine the domain of the function based on the physical constraints of the problem.

Read the "Chemistry in Focus" segment A Four-Wheel-Drive Nanocar. It discusses carbon and copper atoms. Both atoms have stable isotopes. Example $4.2$ had you consider the isotopes of carbon. Copper exists as copper-63 and copper-65. Determine the number of each of the three types of subatomic particles in each of the copper atoms and write their symbols.

Which statements are true about constitutional isomers? (a) They have the same molecular formula. (b) They have the same molecular weight. (c) They have the same order of attachment of atoms. (d) They have the same physical properties.

Work in pairs or small groups to identify the chemistry equipment you use most frequently. Take some time to ask yourself if you know how to use it correctly? Are there any special instructions you need to know before you use it? Write your ideas here (you many want to use extra paper and staple it to this page):

Describe some physical and chemical properties of acids and bases. What is meant by a strong acid or base? Are strong acids and bases also strong electrolytes? Give several examples of strong acids and strong bases.

Replace the underlined words with the correct term. Date rape, abuse, physical abuse, stalking, verbal abuse. Stalking occurs when one person in a dating relationship forces the other to have sexual intercourse.

The combination of physical constants $\alpha=e^2 k / \hbar c$, where $k$ is the Coulomb constant, is known as the fine-structure constant. It appears in numerous relations in atomic physics. Show that $\alpha$ is dimensionless.

Underline all of the action verbs in the sentence below. Identify each verb by writing above it P if it expresses physical activity or M if it expresses mental activity.

Consider the risks before you start your own business.

When an electron in a strontium atom drops from the excited state to the ground state, it emits red light, as explained in the following Chemistry in Action feature. When an electron in a copper atom drops from the excited state to the ground state, it emits blue light. What are the approximate wavelengths of the red light and the blue light? Which color is associated with higher energy?

According to research, which type of aggression is more common among males than females? a. Harmful physical aggression. b. Indirect nonphysical aggression. c. Verbal aggression. d. Ostracism. e. Spreading rumors.

Let F(x, y, z)=ai+bj+ck be a constant vector field and let

$$\sigma$$

be the surface of a solid G. Use the Divergence Theorem to show that the flux of F across

$$\sigma$$

is zero. Give an informal physical explanation of this result.

As the weapons officer aboard the Starship Chemistry, it is your duty to configure a photon torpedo to remove an electron from the outer hull of an enemy vessel. You know that the work function (the binding energy of the electron) of the hull of the enemy ship is $7.52 \times 10^{-19}\ \mathrm{J}.$ What wavelength does your photon torpedo need to be to eject an electron?
