Group the elements into pairs that would most likely exhibit similar chemical properties. It does not matter which pair of elements is pair 1, pair 2, or pair 3, so long as the correct elements are paired. elements are N, As, Br, Mg, Sr, F

“I Hear America Singing” by Walt Whitman

I hear America singing, the varied carols I hear,

Those of mechanics, each one singing his as it should be blithe and strong,

The carpenter singing his as he measures his plank or beam,

The mason singing his as he makes ready for work, or leaves off work,

5

The boatman singing what belongs to him in his boat, the deckhand singing on the steamboat deck, The shoemaker singing as he sits on his bench, the hatter singing as he stands,

The woodcutter's song, the plowboy's on his way in the morning, or at noon intermission or at sundown.

The delicious singing of the mother, or of the young wife at work, or of the girl sewing or washing, Each singing what belongs to him or her and to none else.

10

The day what belongs to the day—at night the party of young fellows, robust, friendly, Singing with open mouths their strong melodious songs.

Directions: Answer the following questions with help from your group. (You still need to turn in your own work! But you can talk about your answers with your group.)

#4  Describe the central image Whitman uses to evoke (bring to mind/ call up) the people of America through the poem. (Scan the poem for words that identify different kinds of workers and work. Focus on the verbs in the poem. What do they tell you about how the poet feels about his subject?)

#5 What is unique about the characters from Line #8 of the poem? (Examine which characters are depicted in that line. Compare them to every other character depicted in the poem.)

#6 What is Whitman’s message about America in this poem? Support your answer with words and phrases from the poem. (What kinds of workers are singing in the poem? What does Whitman want the reader to infer about the kinds of workers that make up America?)

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
