Chapter 13
The Properties of Mixtures: Solutions and Colloids
Last chapter we talked about pure substances ?V liquids and solids. This chapter deals with mixtures, specifically homogeneous mixtures called solutions. A solution is composed of two parts called components:
1. solvent ?V substance present in larger amount
2. solute ?V substance being dissolved
Other terms you will want to remember:

heterogeneous mixture
soluble
insoluble
solubility
solubility limit
dynamic equilibrium vs static equilibrium
?^
(From last chapter)
A solution occurs when two substances are uniformly mixed. A lot of properties of solutions once again depend upon the intermolecular forces present in the solution. In pure liquids, there is only one component and thus, the interaction between particles is the same. In a solution, the solute particles differ from the solvent particles and thus, we have different types of interaction. There are interactions between solute particles, between solvent particles and between solute and solvent particles. The relative strengths and types of the intermolecular forces between the components determines solubility of one substance in another.

Single Mother-hood

Single Mother-hood

In todays American society the growth of womens independence and self-empowerment has given women the confidence to raise their children without a father. Whether the absence of a father is by choice or not, single mothers are on the rise. Recently, actress Jodie Foster accepted the responsibility of motherhood by means of artificial insemination. Although some would support her decision claiming a triumph for the feminist movement, others would argue she is denying her child core family values and a stable gender balanced environment. In an article written by Kathleen Parker, a family columnist, she opposes the idea of encouraging single motherhood. Parker argues that celebrating this notion of single motherhood could not come at a worse time when fatherlessness has now become a national crisis. She draws a correlation between adolescent deviance due to the absence of a father in early childhood. I agree with Parkers argument in that a father presence is essential for the positive socialization of a child. As Parker states, “perfect mothers are only half the equation and are never a substitute for even an imperfect dad.”

Isaac Newton

Isaac Newton

Isaac Newton was a well-known English scientist. He accomplished a lot during his time and influenced the world a great deal. He is considered to have contributed more to science than any other person. His life can be divided into three periods. The first one was his early childhood, he second was the time of his accomplishments, and the third is his later life. Isaac Newton was born on December 25, 1642 in Woolsthorpe, Lincolnshire, England. His family was poor and his parents farmed for a living. His father died three months before he was born. His mother later remarried a minister and Newton went to stay with his grandmother. He attended a grammar school at the age of eleven, but did not do well. His teachers said that he did not pay attention. His mother then decided to pull him out of school and put him in charge of her properties. Newton decided that he did not want to do this, and, with the help of his uncle, Newton convinced his mother to let him return to school. Stokes, the headmaster of the school, saw that Newton had potential, therefore, he put extra time into tutoring, guiding and mentoring

Human Genome Project A genome is defined as the complete collection of an organisms genetic material. The human genome is composed of about 50,000 to 100,000 genes located on 23 pairs of chromosomes in a human cell. It is said that a single human chromosome may contain more than 250 million DNA base pairs, and it is estimated that the entire human genome consists of about 3 billion base pairs. The DNA is gathered through blood samples taken from many different people. Though each person has a unique set of DNA the difference in a given pair of samples is less than 1 percent making the differences pale in comparison to the similarities. The Human Genome Project is an international collaboration of scientists who?s goal is to gain a basic understanding of the genetic blueprint of a human being. This information is found in each cell of the body, encoded in the DNA. The intent of this project is to identify all genes in the nucleus of a human cell, to map where those genes are on the chromosomes of the nucleus, and to determine the seqeuncing or the order of these chemical subunits of the DNA.

Critique

In the ballroom of the student center, Melissa Howard from MTVs, The Real World, spoke on behalf of the Ball State art department. She did speak, but her speaking skills were not the greatest. To start off her speech she did not start out with the normal attention getter that most would expect. She simply said, “Congratulations to all of the winners tonight, now I guess Im here to entertain you.” I didnt think that was the greatest approach to beginning a speech. In fact, she really didnt have much of a speech. It was mostly her just answering questions about her past experiences on the show. She did have a lot of interesting things to say, but it was not quite a speech, it was more of a discussion with the audience. One positive that Melissa did have was that

Law Of Conservation

Law Of Conservation

The Law of Conservation of Energy says that an object with a specific potential energy, when falling will convert that energy to kinetic energy. The purpose of this lab was to prove that this occurs. The apparatus used consisted of a rotating vertical shaft, and a centered horizontal crossbar atop the vertical shaft with wingnuts and masses. A mass hanger was attached to the string and ran over a seemingly frictionless pulley system. When the hanger was dropped, the shaft rotated, causing the horizontal cross bar to go into rotation about the vertical shaft. The linear kinetic energy from the falling masses on the hanger was converted to rotational energy of the horizontal crossbar.
The moment of Inertia of this system should theoretically be I=2MR2 where M is equal to the weight added to one side of the crossbar, I is equal to the inertia, and R is the distance between the vertical shaft and the masses. The theory was tested through treating the radius of the crossbar and the amount of mass as independent variables.
The first set of measurements was taken using two 100g slotted masses on the horizontal cross bar. The distance between the center of the

Biotechnology

Biotechnology & Agriculture

For centuries, many techniques aimed at the improvement in agriculture have been utilized. Today, applied plant science has three overall goals: to increase the crop yield, improve crop quality, and reduce the cost of production. Biotechnology has served a major role in meeting these goals. However, progress has been slower than with medical and other areas of research. Since plants are genetically more and physiologically more complex than single-cell organisms such as bacteria and yeast, the necessary technologies are developing more slowly (Williams, 98).
In one area of plant research, scientists are exploring ways to use genetic modification to create desirable characteristics on food crops. Similarly, agronomists, those who deal with field-crop production and soil management, are looking for ways to harden plants against negative environmental conditions such as soil salinity, drought, alkaline earth metals and anaerobic (lacking oxygen) soil conditions (Stevens, 76).
Genetic engineering methods to improve fruit vegetable crops characteristics are also being explored. These characteristics include taste, texture, size, color, acidity or sweetness, and the ripening process. Methods being explored are a potentially superior strategy to the traditional method of cross breeding. Also, new fermentation applications of biotechnology involving

Reading Your Audiences Like a Book
Did you ever have one of those presentation experiences where you hit everything just right You were really in the zone, firing up your audience while disseminating all of your valuable content. How did you know it was working The answer is fairly obvious?the audience was giving you clues to their appreciation. Their applause, body language, and other signals told you that your presentation was a winner. Now how about those days when you?re off Did the presentation just go downhill from the start, ending in a polite smile from the person who hired you that masked the dissatisfaction she may have been too kind to tell you about, with you just chalking it up to experience Perhaps you made the save, recognizing that you were losing the listeners along the way and adjusted to turn this experience into a winner as well. If so, consider yourself fortunate and skilled in the art of reading your audience. One dual training session that I gave involved a bit of a character act on the part of my partner and I, sort of a good cop/bad cop

Quantum Mechanics As A
Science

Anyone who is not shocked by the quantum theory has not understood it – Niels Bohr

It has been nearly a century since Max Planck proposed that electromagnetic radiation comes in tidy bundles of energy called quanta. Building on this seemingly fragile supposition, scientists erected what is by far the most successful theory in the history. In addition to yielding theories for all the fundamental forces of nature (except gravity), quantum mechanics has accounted for such disparate phenomena as the shining of stars and the order of the periodic table. From it have sprung technologies ranging from nuclear reactors to lasers.

Quantum mechanics is a theory which tries to describe, and predict the behavior of physical systems. The theory was originally designed to make predictions about the behavior of sub-microscopic systems, like atoms and electrons, but since even large-scale systems are composed of atoms, quantum mechanics necessarily comprises a fundamental physical theory–a theory which attempts (at least in principle) to offer as complete an account as can be had of the nature and behavior of physical systems.

All of society is dazzled by the array of new scientific technology and advancements in the realm of scientific research. In this age surely we have seen antibiotics and their charge to the top of the medical profession. Computers have advanced faster, everyone is going faster, communicating better, having more knowledge, and dealing with disease better than ever. Our world and our technology is growing and is compounding faster than ever before. Science has always been a major form of information for our society in this day in age. AND, for as long as I can think, science has been to many people something that clashes with religious beliefs and religious explanations. But, for so long science has not been quite advanced enough so as to truly clash with any religious practice. Sure, we have been testing on animals for quite sometime and that is wrong, but I am talking about very deep issues and circumstances that develop some major problems for us as people as our world presses on. Problems with creation and other such issues that are only now in today?s age a concern. If science goes the
