General Chemistry
General chemistry (sometimes referred to as "gen chem") is offered by colleges and universities as an introductory level chemistry course usually taken by students during their first year. The course is usually run with a concurrent lab section that gives students an opportunity to experience a laboratory environment and carry out experiments with the material learned in the course. These labs can consist of acid-base titrations, kinetics, equilibrium reactions, and electrochemical reactions. Chemistry majors as well as students across STEM Stem or STEM may refer to: Plant structures * Plant stem, a plant's aboveground axis, made of vascular tissue, off which leaves and flowers hang * Stipe (botany), a stalk to support some other structure * Stipe (mycology), the stem of a mushro ... majors such as biology, biochemistry, biomedicine, physics, and engineering are usually required to complete one year of general chemistry as well.

Laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians' offices, clinics, hospitals, and regional and national referral centers. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data. Scient ...

Periodic Table
The periodic table, also known as the periodic table of the (chemical) elements, is a rows and columns arrangement of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry. It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit an approximate periodic dependence on their atomic numbers. The table is divided into four roughly rectangular areas called blocks. The rows of the table are called periods, and the columns are called groups. Elements from the same group of the periodic table show similar chemical characteristics. Trends run through the periodic table, with nonmetallic character (keeping their own electrons) increasing from left to right across a period, and from down to up across a group, and metallic character (surrendering electrons to other atoms) increasing in the opposite direction. The underlying reason for these trends is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AP Chemistry
Advanced Placement (AP) Chemistry (also known as AP Chem) is a course and examination offered by the College Board as a part of the Advanced Placement Program to give American and Canadian high school students the opportunity to demonstrate their abilities and earn college-level credit. AP Chemistry has the lowest test participation rate, with around half of AP Chemistry students taking the exam. Course AP Chemistry is a course geared toward students with interests in chemical biologies, as well as any of the biological sciences. The course aims to prepare students to take the AP Chemistry exam toward the end of the academic year. AP Chemistry covers most introductory general chemistry topics (excluding organic chemistry), including: * Reactions ** Chemical equilibrium ** Chemical kinetics ** Stoichiometry ** Thermodynamics ** Electrochemistry ** Reaction types * States of matter ** Gases, Ideal gases and Kinetic theory ** Liquids ** Solids ** Solutions * Structure of matter ** ...

Medical College Admission Test
The Medical College Admission Test (MCAT; ) is a computer-based standardized examination for prospective medical students (both Allopathic M.D. and Ostepathic D.O.) in the United States, Australia, Canada, and Caribbean Islands. It is designed to assess problem solving, critical thinking, written analysis and knowledge of scientific concepts and principles. Before 2007, the exam was a paper-and-pencil test; since 2007, all administrations of the exam have been computer-based. The most recent version of the exam was introduced in April 2015 and takes 7.5 hours to complete. The test is scored in a range from 472 to 528. The MCAT is administered by the Association of American Medical Colleges (AAMC). History Moss Test: 1928–46 In the 1920s, dropout rates in US medical schools soared from 5% to 50%, leading to the development of a test that would measure readiness for medical school. Physician F. A. Moss and his colleagues developed the "Scholastic Aptitude Test for Medical Stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association Of American Medical Colleges
The Association of American Medical Colleges (AAMC) is a nonprofit organization based in Washington, D.C. that was established in 1876. It represents medical schools, teaching hospitals, and academic and scientific societies, while providing services to its member institutions that include data from medical, education, and health studies, as well as consulting. The AAMC administers the Medical College Admission Test and operates the American Medical College Application Service and the Electronic Residency Application Service. Along with the American Medical Association, the AAMC co-sponsors the Liaison Committee on Medical Education, the accrediting body for all U.S. MD-granting medical education programs. History The AAMC was founded in 1876 at Jefferson Medical College in Philadelphia to establish standards for member medical schools. The first meeting was held on June 2, 1876 and included members from 22 medical colleges. Jefferson Medical College's Dean, John B. Biddle, was ...

Pre-medical
Pre-medical (often referred to as pre-med) is an educational track that undergraduate students in the United States pursue prior to becoming medical students. It involves activities that prepare a student for medical school, such as pre-med coursework, volunteer activities, clinical experience, research, and the application process. Some pre-med programs providing broad preparation are referred to as “pre-professional” and may simultaneously prepare students for entry into a variety of first professional degree or graduate school programs that require similar prerequisites (such as medical, veterinary, or pharmacy schools). Major At most colleges and universities, students do not have the option of pre-medical academic major or minor. A student on a pre-med track may choose any undergraduate major in any field, so long as certain required courses are completed. Such courses are generally focused in the scientific fields of biology, chemistry, organic chemistry, neuroscience, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermodynamics
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, biochemistry, chemical engineering and mechanical engineering, but also in other complex fields such as meteorology. Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scots-Irish physicist Lord Kelvin was the first to formulate a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Bonding
A chemical bond is a lasting attraction between atoms or ions that enables the formation of molecules and crystals. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds, or through the sharing of electrons as in covalent bonds. The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bonds" such as covalent, ionic and metallic bonds, and "weak bonds" or "secondary bonds" such as dipole–dipole interactions, the London dispersion force and hydrogen bonding. Strong chemical bonding arises from the sharing or transfer of electrons between the participating atoms. Since opposite electric charges attract, the negatively charged electrons surrounding the nucleus and the positively charged protons within a nucleus attract each other. An electron positioned between two nuclei will be attracted to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitutes ...

Solubility
In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. The extent of the solubility of a substance in a specific solvent is generally measured as the concentration of the solute in a saturated solution, one in which no more solute can be dissolved. At this point, the two substances are said to be at the solubility equilibrium. For some solutes and solvents, there may be no such limit, in which case the two substances are said to be " miscible in all proportions" (or just "miscible"). The solute can be a solid, a liquid, or a gas, while the solvent is usually solid or liquid. Both may be pure substances, or may themselves be solutions. Gases are always miscible in all proportions, except in very extreme situations,J. de Swaan Arons and G. A. M. Diepen (1966): "Gas—Gas Equilibria". ''Journal of Chemical Physics'', ...

Nuclear Chemistry
Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties. It is the chemistry of radioactive elements such as the actinides, radium and radon together with the chemistry associated with equipment (such as nuclear reactors) which are designed to perform nuclear processes. This includes the corrosion of surfaces and the behavior under conditions of both normal and abnormal operation (such as during an nuclear accidents, accident). An important area is the behavior of objects and materials after being placed into a nuclear waste storage or disposal site. It includes the study of the chemical effects resulting from the absorption of radiation within living animals, plants, and other materials. The radiation chemistry controls much of radiation biology as radiation has an effect on living things at the molecular scale. To explain it another way, the rad ...
