Chapter 1 Summary 1.1 Chemistry A. What Is Chemistry? * Because living and non-living things are made of matter, chemistry affects all aspects of life and most natural events. * Matter- is anything that has mass and occupies space. * Chemistry- is the study of the composition of matter and the changes that matter undergoes. B. Areas of Study * Five traditional areas of study are organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, and physical chemistry. * Organic chemistry- defined as the studies of all the chemicals containing carbon * Inorganic chemistry- defined as the studies of all the chemicals that do not contain carbon * Biochemistry- is the study of the processes that take place in organisms * Analytical chemistry- is the area of study that focuses on the composition of matter * Physical chemistry- area that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change C. Pure and Applied Chemistry * Pure chemistry- is the pursuit of chemical knowledge for its own sake * Applied chemistry- is the research that directed toward a practical goal or application * Pure research can lead to an application, but an application can exist before research is done to explain how it works 1. Nylon * Hermann Staudinger proposed that cotton and silk contained small units joined together like links in a chain 2. Aspirin * By 1950, some doctors began to recommend a low daily dose of aspirin for patients who were at risk for a heart attack * Many heart attacks occur when blood clots block the flow of blood through arteries in the heart 3. Technology * Technology- means by which a society provides its members with those things needed and desired D. Why Study Chemistry? * Chemistry can be useful in explaining the natural world, preparing people for career opportunities, and producing informed
The Octet Rule
Atoms form chemical bonds so that they have an octet of valence electrons, either by gaining, losing, or sharing valence electrons.
When atoms bond together, they each want a set of 8 valence electrons.

1. Living organisms make compounds which are important sources of energy
* outline the role of photosynthesis in transforming light energy to chemical energy and recall the raw materials for this processco2+h2oglucose+o2+h2othis is then stored as carbs and starch |
* outline the role of the production of high energy carbohydrates from carbon dioxide as the important step in the stabilisation of the sun’s energy in a form that can be used by animals as well as plants harnesses….
SUMMARY AND CONCLUSION
Silver nanoparticles are nanoparticles of silver composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Various shapes and sizes of nanoparticles are synthesized by physical, chemical and biological methods. The Chrysophyllum canito leaf extracts were used for silver nanoparticles synthesis. In this study utterly revealed the best milli molar concentrations of silver nanoparticles synthesis in diverse solvents such….
Summary of chemistry lab report
The two factors which affect the yield of products in a chemical reaction is the amount of starting materials (reactants) and the percent yield of the reaction. Many experimental conditions for example temperature, and pressure can be adjusted to increase yield of the desired product, in chemical reaction, but because chemicals react according to fixed mole ratios( stoichometrically), the only limited….
CHAPTER # 1
A. Chemistry, a branch of physical science, is the study of the composition, properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds. Chemistry is also concerned with the interactions between atoms and various forms of energy
Q.DEFINE THE BRANCHES OF CHEMISTRY.
* Physical chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena….
