Organic compounds number in the millions, far outnumbering inorganic compounds. The reason for this is due to the uniqueness of carbon's structure and bonding abilities.

What are organic compounds?

Any of a wide range of chemical compounds in which one or more carbon atoms are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.

Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.

Organic compounds in the body include carbohydrates, lipids (including phospholipids), proteins, nucleotides, and nucleic acids.

Water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and some acids, bases, and salts are the most important inorganic compounds. The human body is 60-75% water.

Organic compounds outnumber inorganic compounds by orders of magnitude. This is because of the uniqueness of carbon's structure and bonding abilities.

Thus, this way, one can account for the great number, size, and complexity of organic compounds.

I am much grieved, for I expected, if I did not defeat you, to hold out much longer, and give you more trouble before I surrendered. I tried hard to bring you into ambush, but your last general understands Indian fighting. The first one was not so wise. When I saw that I could not beat you by Indian fighting, I determined to rush on you, and fight you face to face. I fought hard. But your guns were well aimed. The bullets flew like birds in the air, and whizzed by our ears like the wind through the trees in the winter. My warriors fell around me; it began to look dismal. I saw my evil day at hand. The sun rose dim on us in the morning, and at night it sunk in a dark cloud, and looked like a ball of fire. That was the last sun that shone on Black Hawk. His heart is dead, and no longer beats quick in his bosom. He is now a prisoner to the white men; they will do with him as they wish. But he can stand torture, and is not afraid of death. He is no coward. Black Hawk is an Indian.He has done nothing for which an Indian ought to be ashamed. He has fought for his countrymen, the squaws and papooses, against white men, who came, year after year, to cheat them and take away their lands. You know the cause of our making war. It is known to all white men. They ought to be ashamed of it. The white men despise the Indians, and drive them from their homes. But the Indians are not deceitful. The white men speak bad of the Indian, and look at him spitefully. But the Indian does not tell lies; Indians do not steal.An Indian who is as bad as the white men, could not live in our nation; he would be put to death, and eat [sic] up by the wolves. The white men are bad school-masters; they carry false looks, and deal in false actions; they smile in the face of the poor Indian to cheat him; they shake them by the hand to gain their confidence, to make them drunk, to deceive them, and ruin our wives. We told them to let us alone; but they followed on and beset our paths, and they coiled themselves among us like the snake. They poisoned us by their touch. We were not safe. We lived in danger. We were becoming like them, hypocrites and liars, adulterers, lazy drones, all talkers, and no workers.We looked up to the Great Spirit. We went to our great father. We were encouraged. His great council gave us fair words and big promises, but we got no satisfaction. Things were growing worse. There were no deer in the forest. The opossum and beaver were fled; the springs were drying up, and our squaws and papooses without victuals to keep them from starving; we called a great council and built a large fire. The spirit of our fathers arose and spoke to us to avenge our wrongs or die . . . . We set up the war-whoop, and dug up the tomahawk; our knives were ready, and the heart of Black Hawk swelled high in his bosom when he led his warriors to battle. He is satisfied. He will go to the world of spirits contented. He has done his duty. His father will meet him there, and commend him.Black Hawk is a true Indian, and disdains to cry like a woman. He feels for his wife, his children and friends. But he does not care for himself. He cares for his nation and the Indians. They will suffer. He laments their fate. The white men do not scalp the head; but they do worsethey poison the heart, it is not pure with them. His countrymen will not be scalped, but they will, in a few years, become like the white men, so that you cant trust them, and there must be, as in the white settlements, nearly as many officers as men, to take care of them and keep them in order.Farewell, my nation. Black Hawk tried to save you, and avenge your wrongs. He drank the blood of some of the whites. He has been taken prisoner, and his plans are stopped. He can do no more. He is near his end. His sun is setting, and he will rise no more. Farewell to Black Hawk.Read this sentence from Paragraph 5 of the speech.The white men do not scalp the head; but they do worsethey poison the heart, it is not pure with them.Which statement best describes the effect of the imagery in the sentence?A.) By evoking the deadly image of poison, Black Hawk describes how the white men will murder his people.B.) By evoking the horrific image of scalping, Black Hawk makes his viewpoint of the white men's actions clear.C.)
