Your exam will be multiple choice Exam # 1 Introductory Chemistry Be sure to show your set up for all mathematical problems. Your answers must have the correct number of significant digits and the correct units. I. Chemistry is a quantitative science therefore we must make measurements. All measurements have an uncertainty that we need to be aware of in our calculations. A. We need to be able to determine the number of significant figures in a measurement. For the following measurement state the

Solutions (Week-01) Chapter-01 1-12 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are mw =V =(1000 kg/m3)(0.2 m3) = 200 kg mtotal = mw + mtank = 200 + 3 = 203 kg Thus‚ 1-14 The variation of gravitational acceleration above the sea level is given as

Greenhouse effects and global warming are an uprising environmental issue. The greenhouse effect is the process by which absorption and emission of infrared radiation by gases are released in the atmosphere. The major greenhouse gases are water vapor (36 -70%)‚ carbon dioxide CO2 (9-26%)‚ methane CH4 (4-9%)‚ and ozone O3 (3-7%). Since the industrial revolution‚ human activity has increased the amount of greenhouse gases‚ leading to increased levels of CO2‚ methane and troposphere ozone. Fossil fuels

Chapter 1 * What is Chemistry? -it is the study of the composition of substances and the changes they undergo. * What are the 5 branches of chemistry? * Organic chemistry‚ inorganic chemistry‚ analytical chemistry‚ physical chemistry‚ biochemistry. * What is the difference between a theory and law? -a theory is a thoroughly tested explanation of why experiments give certain results. A scientific law is a concise statement that summarized the results of a broad spectrum of observations

Part I: Bonding A) Group # and Valence Electrons -is used to describe the column in which an element is in. i.e.‚ Lithium is in group 1. *Group number tells you how many valence electrons a specific element has. i.e.‚ Aluminum has 3 valence electrons. B) Ionic Bonding -Ionic bonds form F.U.’s (formula units) -A bond between a metal and a non metal -Occurs when an atom has lost or gained an electron **BRING YOUR ION SHEET FOR NAMING** C) Covalent Bonding -Covalent bonds form molecules

measured by this system. There are many different techniques to measure all of the metric system. Length is measured by meters. This is the measurement of distance between an object from end to end. Temperature in the metric system is measured by Kelvin. Volume is the amount of space that a three dimensional object takes up. This is measured by cubic meter. A graduated cylinder is often used to measure the volume. Throughout out the lab we took all these different measurements‚ and also expanded
