Hailie Armstrong Ms. Gorges U4 L8 Chemistry 11/19/14 Modeling Molecules Introduction: You can represent a molecule two-dimensionally‚ as a structural formula or electron dot structure. Although such models are useful in certain contexts‚ they do not accurately represent bond angles between atoms or shapes of molecules. In this activity‚ you will construct three-dimensional models of several molecules. You will use electron dot structures and structural formulas to inform how you construct the

The effect on the balloon is shown in the diagram below: [pic] Explain this observation based on the Kinetic Molecular Theory. In your response‚ be sure to • describe the effect of temperature on the kinetic energy of the gas particles. • describe the motion of the gas particles. • describe the effects of this

Renaissance kicked off called Proto-Renaissance‚ and the factors contributing to its success. The three factors that contributed to the success of this transition were‚ where it began‚ the influence of humanism‚ and artistic innovations contributed by artists. These factors are considered to be essential in the new coming artistic style of naturalism. The origins of Renaissance art can be traced to Italy in the late 13th and early 14th centuries. During this period called “Proto-Renaissance‚” sometimes

DNA – RNA Notes The sugar in DNA is called deoxyribose. The sugar in RNA is called ribose. -RNA is a single strand of nucleotides. DNA is made of two strands of nucleotides. -DNA is a double helix with hydrogen bonds linking the nitrogen bases. RNA is a linear strand with no hydrogen bonds. -The bases of DNA are: Adenine‚ Thymine‚ Cytosine‚ and Guanine. The bases of RNA are: Adenine‚ Uracil‚ Cytosine‚ and Guanine. -RNA does not have Thymine‚ and DNA does not have Uracil. -In DNA

What makes a good movie good? Name: Hilal Mohammed I.D no.: 61288 What makes a good movie good? I admire movies and cannot live without them. Some movies taught me important principles in my life‚ some created memories that will never get erased and some made me laugh so hard till I cried; that is why I love movies. However‚ there are several movies that I watched‚ but I do not remember their story at all. For a movie to affect me and stay in my memory‚ it should include three important factors:

Campbell’s Biology‚ 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5‚ the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent

molecule of water A chemist’s view of the world is not as narrow as one might think! Yes‚ we start with the atom‚ and then go on to the rules governing the kinds of structural units that can be made from them. We are taught early on to predict the properties of bulk matter from these geometric arrangements. And then we come to H2O‚ and are shocked to find that many of these predictions are way off‚ and that water (and by implication‚ life itself) should not even exist on our planet! But we soon

Do Good Fences Make Good Neighbors? addresses the historical impact of strategic barriers‚ defined here as "continuous or mutually supporting works denying the enemy avenues of attack across a front." In his introduction‚ Brent Sterling argues for the relevance of such an appraisal given the renewal of interest in strategic defense around the world (old fashioned walls‚ as well as more novel missile defenses) and the shallow debate surrounding it‚ the "dynamic" of which "is for critics and proponents

Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides- Two

There are many qualities that are desirable in a neighbor. A good neighbor is someone who does not mow over your flowers or does not play music too loud. Robert Frost once said that "A good fence makes a good neighbor." I agree and disagree with this statement. Most people want a solid fence between their house and their neighbors. I only the other hand‚ see a fence as a way to put yourself in a space that is just yours for nobody else to enter. I think that a fence can be symbolic of an emotional
