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 titration, acid-base titrations, Chemical kinetics, kinetics, Chemical equilibrium, equilibrium reactions, and Electrochemistry, electrochemical reactions. Chemistry majors as well as students across Science, technology, engineering, and mathematics, STEM majors such as biology, biochemistry, biomedicine, physics, and engineering are usually required to complete one year of general chemistry as well. Concepts taught The concepts taught in a typical general chemistry course are as follows: *Stoichiometry *Conservation of energy *Conservation of mass *Atom, Elementa ...

Laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratories are found in a variety of settings such as schools, universities, privately owned research institutions, corporate research and testing facilities, government regulatory and forensic investigation centers, physicians' offices, clinics, hospitals, regional and national referral centers, and even occasionally personal residences. 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 ...

Periodic Table
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows (" periods") and columns (" groups"). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order of their atomic numbers an approximate recurrence of their properties is evident. The table is divided into four roughly rectangular areas called blocks. Elements in the same group tend to show similar chemical characteristics. Vertical, horizontal and diagonal trends characterize the periodic table. Metallic character increases going down a group and from right to left across a period. Nonmetallic character increases going from the bottom left of the periodic table to the top right. The first periodic table to become generally accepted was that of the Russian chemist Dmitri Mendeleev in 1869; he formulated the periodic law as ...

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 credits at certain colleges and universities. The AP Chemistry Exam has the lowest test participation rate out of all AP courses, 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 ...

Medical College Admission Test
The Medical College Admission Test (MCAT; ) is a Computer-based testing, computer-based standardized examination for prospective medical students in the United States, Canada, Australia, and the Offshore medical school, 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 approximately hours to complete, including breaks. 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: 1928–1946 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pre-medical
Pre-medical (often referred to as pre-med) is an educational track that undergraduate students mostly 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). In Australia In Australia, a number of universities offer a three- or four-year Bachelor of Medical Science, Bachelor of Health Sciences or Biomedical Science degree, which is similar in content and aims to pre-med courses in the US. In Australia, there are two pathways to becoming a doctor. One is undergraduate entry into medical school and ano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermodynamics
Thermodynamics is a branch of physics that deals with heat, Work (thermodynamics), 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 quantity, physical quantities but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to various topics in science and engineering, especially physical chemistry, biochemistry, chemical engineering, and mechanical engineering, as well as other complex fields such as meteorology. Historically, thermodynamics developed out of a desire to increase the thermodynamic efficiency, efficiency of early steam engines, particularly through the work of French physicist Nicolas Léonard Sadi Carnot, Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win ...

Chemical Bonding
A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. 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, or some combination of these effects. Chemical bonds are described as having different strengths: 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. Since opposite electric charges attract, the negatively charged electrons surrounding the nucleus and the positively charged protons within a nucleus attract each other. Electrons shared between two nuclei will be attracted to both of them. "Constructive quantum mechanical wavefunction interference" stabilizes the paired nuclei (see Theories of chemical bonding). Bonded nuclei maintain an optimal distance (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solubility
In chemistry, solubility is the ability of a chemical substance, substance, the solute, to form a solution (chemistry), 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 wikt:saturated#Chemistry, 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 "miscibility, 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 radiation alters th ...
