Differentiate between the significance of the coefficients in a balanced chemical equation and the significance of the subscripts in a chemical formula.  · Coefficients show the correct proportions of atoms and molecules in a chemical reaction. They are normal sized numbers placed at the beginning of the chemical formulas in a chemical reaction during the process of balancing. They tell how many of an entire chemical formula is in a reaction.  · Subscripts show the correct proportions of atoms/ions in a chemical formula. They are the small numbers within the chemical formula. They tell how many individual atoms/ions are present. 2. State the Law†¦show more content†¦7. What is plasma?  · Plasma has neither a definite volume nor a definite shape.  · Plasma is often seen within ionized gases.  · Plasma is distinct from a gas because it possesses unique properties: o It contains free electrical charges (not bound to atoms or ions) o It can be produced by heating and ionizing a gas.  · Plasma is often found in areas of the planet/universe where extremely high heats are possible and gases exist to help create the plasma. 8. Put hydrogen bonds, dispersion forces and dipole-dipole forces in order of how strong they are and give an example of each type of attraction.  · Strongest = Hydrogen bonds which have hydrogen attached to a fluorine, oxygen, or nitrogen (Example: Oxygen’s attraction to other hydrogens in a bunch of H2O’s)  · Medium Strength = Dipole-Dipole bonds which occur between the slight positive end of one polar molecule and the slight negative end of another polar molecule (Example: Nitrogen’s attraction to other hydrogens in a bunch of NH3’s)  · Weakest = Dispersion forces which occur in any covalently bonded molecule (Example: Hydrogen’s attraction to other hydrogens in a bunch of CH4’s) Ø Note 1: These are intermolecular forces of attraction so they occur OUTSIDE of the molecules! Ø Notes 2: One covalent bond can be all three types at once. 9. Why do polar compounds tend to have higher melting boiling points than nonpolar compounds?

Essay Psychoanalytic Theory and the Defense Mechanisms

The introduction of the psychoanalytic theory into the field of psychology in the late 19th century and early 20th century by Sigmund Freud provided an innovative approach toward the examination and treatment of an individual’s behaviors. Through Freud’s definition of psychoanalysis, the idea that behaviors are not random, but rather full of significance, was encapsulated. In general terms Freud viewed psychoanalysis as an attribution of thoughts and actions to an individual’s unconscious motives and conflicts through the use of personality and therapeutic methods. Within this theory Freud developed an idea of an individual’s mind by analyzing it in comparison to an iceberg. Much like an iceberg, which contains various regions that are†¦show more content†¦Throughout childhood and adolescence the influence of authoritative figures plays a crucial role in the emergence of conscious ideals. The final division of the human mind, the ego, possesses a critical position in mediating between the demands and drives of the id with the constraints set in place by the superego in order to meet the demands of reality. An ego-driven person maintains the ability to understand themselves along with the outside world. This capability provides such individuals with an insight into methods of controlling their drives in a socially acceptable manner. The three divisions of the mind that Freud emphasizes play an essential role in the psychoanalysis theory. When examining an individual’s thoughts and actions through personality and therapeutic methods, the three divisions prove to be significant. Freud demonstrates this importance by recognizing that human personality ascends from a struggle between impulses and restraints. This acknowledgment portrays personality as an individual’s effort to resolve this struggle between the three divisions of the mind. Overall, Freud’s division of the human mind presents the field of psychology with a methodical technique with which to classify abnormal behaviors. When coping with abnormal behaviors or situations beyond an individual’s control, the utilization of defense mechanisms provide an effective release. Defense mechanisms serve as strategies that unconsciouslyShow MoreRelatedPsychoanalytic and Trait Approaches Personality Assessment Essay996 Words   |  4 PagesPsychoanalytic and Trait Approaches Personality Assessment PSY/250 Psychoanalytic and Trait Approaches Personality Assessment I have always attributed personality as being a culmination of environment first, biology second, and traits, or what my understanding of them was.

Essay The Chrysanthemums and The Worker in Sandalwood

The Chrysanthemums by John Steinbeck and The Worker in Sandalwood by Majorie Pickthall Over the past few months in class we have learned about many aspects of literature. Some examples of them are characterization, setting, style, tone, allegory, theme, and symbolism. I chose to write this essay about the symbolism aspect that is featured in so many great works of literature. Two such stories that we have read in which symbolism is demonstrated is in The Chrysanthemums by John Steinbeck, and The Worker in Sandalwood by Majorie Pickthall. In The Chrysanthemums, Steinbeck tells a story of a married couple living on a farm. The husband, Henry Allen, works most of the day while his wife, Elisa Allen, spends most of her time†¦show more content†¦During the story a stranger wanders on to the farm looking for work. He mends and repairs old pots, scissors and other items. At first, Elisa tells him that she has no work for him, but the stranger begins to tell her of a woman he had come across that has a beautiful garden but no Chrysanthemums. Elisa becomes so excited at the chance to give the man some of her flowers to give to her, that she even figures to let him do a little work. She gives him some items to fix along with some Chrysanthemums to deliver. Later that day on their way to dinner the Allens come across the flowers tossed on the side of the road. Elisa was heart-broken over seeing something she loved so much just thrown aside like garbage. To her, the Chrysanthemums symbolized her children. In The Worker in Sandalwood Pickthall tells a story of a man named Hyacinthe. He is asked to work all night by his boss, Pierre LOreillard, to finish building a cabinet. But this isnt just any night, this is Christmas Eve. During the night, a stranger comes to Hyacinthes door and asks to come in. He offers to help Hyacinthe with his work while he gets some rest. While Hyacinthe rests the stranger completes all of the work and with only a smile, leaves. There are a few things that he also did that made the reader and Hyacinthe think. He said he was bred a carpenter and also when he first arrived he had an injured sparrow with him that magically was healed when the sun rose. This stranger symbolized Jesus sent

Dune

Dune-lots Of Errors Essay Dune by Frank Herbert is one of the greatest Science Fiction novels of all time. The story is about Paul Atreids as he tries to take back his planet (Arrakis, a.k.a Dune a pure desert world. It is also the only place where spice can be found. Spice is a drug that gives people the ability to see the future, health and long life, (hence the saying, Health and long life are the gifts of the spice, Dune the Sci Fi mini-series)) from the Harrkonnens the Atreids mortal enemy. The book is based in the year 10,946 B.J (Bielgium Jihad) in the Imperium of man under the rule of Shaddam the IV. The main characters are The Baron and Paul Atreids. Paul Atreids is the son of Duke Leto Atreids and the lady Jessica. He is MuadDib the Fremen messiah (The Fremen are the natives of Dune and the greatest fighters in the known universe.). The Baron is the ruler of Giedi prime. He is sadistic and he hates the Atreids because an Atreids had the ruler of House Harrkonnen banished for cowardice. The book star ts off with House Atreids moving to Arrakis. Paul father, Leto sends off men to recruit the Fremen to his cause because he believes the Harrkonnens will attack Arrakis (for now on I will call it by its Fremen name Dune). The Harrkonnens make an attempt on Pauls life and a traitor shuts down the Atreids palaces shield. Soon Harrkonnen troops and Sardaukar (The emperors shock troops) attack dune. Without the Fremens aid the Harrkonnens capture dune and kill Leto and send Paul and his mother out into the deep desert to die. After the assault the Sadaukar leave. The Harrkonnens believing Paul dead begin to solidify their hold on Dune. After killing their captors Paul and Jessica escape. As they run, a worm (A giant worm, Usually about a kilometer long and about thirty feet wide with sharp teeth) tries to eat the pair but they escape into a cave. Later Duncan Idaho, a loyal Lieutenant, picks them up and brings them to a hidden Fremen base. There Sardaukar attacks them again and Duncan dies buying time for Paul and Jessica to get away. Later they are found by a group of Fremen who think Paul is the MuadDib (their messiah). After Paul kills a non-believer the Fremen begin to worship Paul. He teaches them the Wierding Way (A technique of fighting). He gets a bodyguard of fredakyin (Fremen death Commandos). With his troops Paul begins a guerilla war against the Harrkonnens and their spice production bring it to a halt. He then meets a Fremen girl named Chani falls in love with her and takes her as his concubine. Since the spice production stops the emperor himself comes to Arrakis and prepares to kill MuadDib. With the emperor landing on dune, MuadDib attacks with all of the Fremen on the planet. He takes the emperor and the last surviving Harrkonnen prisoner. Paul then fights a duel with the Harrkonnen a kills him. Paul then marries the emperors daughter and becomes the new emperor. The story ends there. I enjoyed this book greatly. I liked this book because of its strong plot and good characters. Also because of the storys many action packed moments. Unfortunately I learned nothing from this book. I recommend this book to anyone who likes Science Fiction.
