A: You need to take Chem 111/117-112/118, 221-222, 340, 420, and an elective.  You can use 340, 420, and internship/342 towards the concentration.  And for the major electives, you'll take two of 460, 342 (if you did an internship), and 270, to avoid overlaps.

A: VOCs can be harmful to your health and you should have your well water tested for them on a regular basis. If your well water tests positive for elevated levels of VOCs, you should speak to a well water professional about treatment options.

A: If you're on a Pro or Premium plan and you drop or withdraw from a class, make sure to cancel your membership as soon as possible so you don't get charged again.

A: Chemmunity is for anyone who needs help with Organic Chemistry.

A: The SSSC offers assistance with writing lab reports, tutoring, and supplemental instruction in the following courses: General Chemistry 1101 and 1102, General Chemistry 1111 and 1112, and Organic Chemistry 2001 and 2002. If students need help with lab reports, GSAs and tutors assist with any lab-related questions, and writing tutors further assist in improving the writing.

A: The NEW CHEM 41 series is for students starting organic chemistry for the first time in Fall 2022.
-The NEW CHEM 40 series is for everyone else, including life sciences majors, who will be starting organic chemistry for the first time in Fall 2022.
-The OLD CHEM 40 series was our "old" curriculum organic chemistry sequence for students who started on the organic chemistry sequence prior to Fall 2022.

A: The stockroom may not have everything you need, so it's always best to check with them first. If you're looking for a specific concentration of a solution, you may need to ask for it specifically. The same goes for buffers and standards.

A: The barcode field is used for entering a barcode sequence from a RFID Tag associated with each container.

A: It is an international, peer-reviewed, Open Access journal
-It covers all areas of organic chemistry
-The content is freely accessible online immediately upon publication
-It is published and completely funded by the Beilstein-Institut, a non-profit foundation located in Frankfurt am Main, Germany
-Editor-in-chief is Peter H. Seeberger, Max Planck Institute of Colloids and Interfaces, Potsdam, Germany

A: Benzene is a carcinogenic substance that can cause leukemia, lymphoma and other lung cancers. Those who are exposed to high levels of benzene, like chemical workers and commercial gasoline haulers, are at the highest risk for these diseases. If you have been exposed to benzene and have developed an illness as a result, you should speak with a West Virginia personal injury lawyer to see if you have a case.

A: If you are a first-year student planning to take either Chem 105 or Chem 111A, you should take the online general chemistry diagnostic exam and complete the Chemistry Background Survey.

A: Complete the Chemistry Diagnostic and Survey before meeting with your advisor to review your fall course selection.

A: The diagnostic exam is a way for you to test your knowledge of the material and to see how well you understand the concepts. The exam is not a pass/fail test, but it will give you an idea of where you stand and what you need to work on.

A: Your four-year academic advisor will discuss your diagnostic exam results and the information you shared in the survey with you at your first meeting together. At that time, you will be informed about which General Chemistry sequence (Chemistry 105/106 or Chemistry 111A/112A) and supplementary aids we recommend for you.

A: If you need accommodations, first get approval from disability resources, then contact Dr. Jia Luo (jluoa@wustl.edu).

A:

A: Weeds are a symptom of a problem in the soil. Dandelions love compaction, creeping Charlie likes a pH imbalance and clover thrives in low nitrogen conditions. The answer is simple: correct the soil problem and the weeds go away. The microbial life available in the fertilizers, compost tea and other organic products we use relieve and correct most weed-generating soil problems.

A: If you have a question about your homework, post it in the private homework help group and one of our moderators will answer it for you.

A: We grow food in climate-controlled indoor farms in a variety of locations.

A: University-level chemistry is more difficult than high-school AP chemistry, requiring greater depth of understanding and the ability to apply multiple concepts to solve problems.

A: Students in either course sequence will be prepared to take Organic Chemistry I (Chem 261) and Organic Chemistry II (Chem 262).

A: The Chemistry 105/106 sequence is recommended for students who are interested in pursuing a career in chemistry or a related field. The Chemistry 111A/112A sequence is recommended for students who are interested in pursuing a career in medicine or a related field.

A: The Department of Chemistry offers free tutoring for all UCI students on a walk-in basis, and also provides LARC sessions for a fee. Tutors prepare weekly worksheets and hold office hours for students to come and ask questions. Review sessions for exams are also provided.

A: Organic lawn care is safer for children, pets, wildlife, and the environment.

A: Chem 111A covers quantum mechanics and atomic wavefunctions in greater depth than Chem 105, while Chem 106 covers most of the same material as Chem 112A but with advanced applications removed.

A: This course covers the development of chemistry from early atomic theory to modern descriptions of structure, bonding, and intermolecular interactions.

A: This course covers chemical equilibrium, thermodynamics, and kinetics at a fundamental level, with an emphasis on in-class problem solving.

A: The electron and its properties are responsible for atomic structure, atomic orbitals, atomic spectroscopy, chemical periodicity, the arrangement of the periodic table, chemical bonding, molecular geometry, and intermolecular forces.

A: This course covers chemical equilibrium, thermodynamics, and kinetics, and their roles in describing and determining chemical processes. The key concepts of chemical equilibrium for gas-phase reactions, heterogeneous (multi-phase) reactions, acid-base reactions, and solubility equilibria are introduced first. The next section of the course describes chemical thermodynamics with a focus on heat, work, internal energy, enthalpy, entropy, and Gibbs free energy. Key connections are made between
