| post lab questions chemistry answers: The Zinc and Iodine Book Stephen DeMeo, 2019-05-15 <p>This book is for chemistry teachers who are thinking about reinventing their laboratory experiments that they provide to their students. More than a collection of experiments, it is an example of using a chemical theme to teach chemistry. Instead of introducing many different chemicals per experiment as is the norm in most lab manuals, this novel resource focuses on two commonly found elements: Zinc and Iodine.<br><br>So what is so special about these elements? At the heart of this resource is a colorful cyclic reaction between zinc and iodine, one that produces a compound that can decompose back to its original elements. This unique phenomenon demonstrates that matter not only changes, but is also conserved through a chemical reaction. Knowing that a compound can be the "same but different" than the reactants that formed it, is to understand the essence of chemical change.<br><br>Complementing this reaction, this book contains experimental activities that utilize the zinc and iodine theme to scaffold new concepts such as the properties of matter, solid and gas stoichiometry, equilibrium, kinetics, acid-base chemistry, and electrochemistry. This teacher tested resource focuses on a set of safe substances that are appropriate for high school teachers who provide an advanced chemistry placement course and for college instructors teaching a first-year chemistry laboratory sequence. <br></p> |

| post lab questions chemistry answers: Experimental Organic Chemistry John C. Gilbert, Stephen F. Martin, 2006 This proven and well-tested laboratory manual for organic chemistry students contains procedures for both miniscale (also known as small scale) and microscale users. This lab manual gives students all the necessary background to enter the laboratory with the knowledge to perform the experiments with confidence. For the microscale labs, experiments were chosen to provide tangible quantities of material, which can then be analyzed. Chapters 1-2 introduce students to the equipment, record keeping, and safety of the laboratory. Chapters 3-6, and 8 are designed to introduce students to laboratory techniques needed to perform all experiments. In Chapters 7 and 9 through 20, students are required to use the techniques to synthesize compounds and analyze their properties. In Chapter 21, students are introduced to multi-step syntheses of organic compounds, a practice well known in chemical industry. In Chapter 23, students are asked to solve structures of unknown compounds. The new chapter 24 introduces a meaningful experiment into the textbook that reflects the increasing emphasis on bioorganic chemistry in the sophomore-level organic lecture course. This experiment not only gives students the opportunity to accomplish a mechanistically interesting and synthetically important coupling of two a-amino acids to produce a dipeptide but also provides valuable experience regarding the role of protecting groups in effecting synthetic transformations with multiple functionalized molecules. |

| post lab questions chemistry answers: Integrated Approach to Coordination Chemistry Rosemary A. Marusak, Kate Doan, Scott D. Cummings, 2007-03-30 Coordination chemistry is the study of compounds formed between metal ions and other neutral or negatively charged molecules. This book offers a series of investigative inorganic laboratories approached through systematic coordination chemistry. It not only highlights the key fundamental components of the coordination chemistry field, it also exemplifies the historical development of concepts in the field. In order to graduate as a chemistry major that fills the requirements of the American Chemical Society, a student needs to take a laboratory course in inorganic chemistry. Most professors who teach and inorganic chemistry laboratory prefer to emphasize coordination chemistry rather than attempting to cover all aspects of inorganic chemistry; because it keeps the students focused on a cohesive part of inorganic chemistry, which has applications in medicine, the environment, molecular biology, organic synthesis, and inorganic materials. |
| post lab questions chemistry answers: Course Success in the Undergraduate General Chemistry Lab Thomas Elert, 2019-11-15 Stetig hohe Studienabbruchquoten in den MINT-Fächern an deutschen Hochschulen, welche auch aus geringem Kurserfolg in einführenden Laborpraktika resultieren könnten, und die wachsende Kritik an der Qualität und Wirksamkeit ebendieser machen eine eingehende Betrachtung von Laborpraktika notwendig. Diese Studie untersuchte die Lernziele des Laborpraktikums Allgemeine Chemie für Lehramtsstudierende im ersten Semester sowie Faktoren für den Kurserfolg, um daraus Aussagen über den Stellenwert von Laborpraktika in der universitären Bildung, insbesondere für langfristigen Studienerfolg, abzuleiten. Dazu wurde ein theoretisches Modell zu Grunde gelegt, welches das Vorwissen der Studierenden und die Lernzielpassung zwischen Studierenden und Lehrenden als zwei entscheidende Faktoren für Kurserfolg berücksichtigt. Constantly high student dropout rates in STEM subjects at German universities, which could be the result of low course success in introductory laboratory courses among other things and increasing criticism about their quality and effectiveness necessitate these laboratory courses to be examined thoroughly. This study investigated the learning goals of the General Chemistry laboratory course for first-year students in teacher training and factors for course success in order to make statements about the significance of laboratory courses for university education, particularly for long-term study success. For this purpose, a theoretical model that assumes the students prior knowledge and learning goal alignment between students and their lab instructors to be two defining factors for lab course success was used as a framework. |

| post lab questions chemistry answers: Innovative Methods of Teaching and Learning Chemistry in Higher Education Ingo Eilks, Bill Byers, 2015-11-06 Two recent initiatives from the EU, namely the Bologna Process and the Lisbon Agenda are likely to have a major influence on European Higher Education. It seems unlikely that traditional teaching approaches, which supported the elitist system of the past, will promote the mobility, widened participation and culture of 'life-long learning' that will provide the foundations for a future knowledge-based economy. There is therefore a clear need to seek new approaches to support the changes which will inevitably occur. The European Chemistry Thematic Network (ECTN) is a network of some 160 university chemistry departments from throughout the EU as well as a number of National Chemical Societies (including the RSC) which provides a discussion forum for all aspects of higher education in chemistry. This handbook is a result of one of their working groups, who identified and collated good practice with respect to innovative methods in Higher Level Chemistry Education. It provides a comprehensive overview of innovations in university chemistry teaching from a broad European perspective. The generation of this book through a European Network, with major national chemical societies and a large number of chemistry departments as members make the book unique. The wide variety of scholars who have contributed to the book, make it interesting and invaluable reading for both new and experienced chemistry lecturers throughout the EU and beyond. The book is aimed at chemistry education at universities and other higher level institutions and at all academic staff and anyone interested in the teaching of chemistry at the tertiary level. Although newly appointed teaching staff are a clear target for the book, the innovative aspects of the topics covered are likely to prove interesting to all committed chemistry lecturers. |
