CHEMLAB SAFETY SERIES

These problems can be solved in 4 simple steps. For example, a problem might provide the equation 2 A + 3 B → 3 C and ask, 'given 25 grams of B and unlimited amount of A, how much C will be produced?' This is called a mass-mass problem. The most common stoichiometric problem will present you with a certain amount of a reactant and then ask how much of a product can be formed. It is a very mathematical part of chemistry. Stoichiometry deals with calculations about the masses (sometimes volumes) of reactants and products involved in a chemical reaction. The Merriam-Webster dictionary defines stoichiometry as 'a branch of chemistry that deals with the application of the laws of definite proportions and of the conservation of mass and energy to chemical activity'. Rows are called periods, and display properties known as periodicity. The elements are arranged so they are in columns with similar chemical properties. They are numerically ordered by their atomic number, which is the number of protons in the nucleus of an atom. The periodic table of the elements organizes the known elements by properties.

General Chemistry This section includes general chemistry knowledge that is applicable to most or all topics.

1 stand-alone, non-graphing, non-programmable calculator per student.

1 double-sided note sheet per team (sheet protectors and lamination allowed).

Lab coat, closed-toed shoes, etc.-see rule 2.c for exact safety parameters (Required).

For topic-specific information, please see the topic rotation, as this page only contains general information that applies to all topics.Ĭhemistry Lab has been held every year in Division C since 1987.Ĭhemistry Lab typically rotates between several topic area, with two topics at a time, and one topic rotating in/out each year.Īs of 2019, the following materials are allowed: Since this event rotates topics, each topic constitutes its own page.

Teams will complete one or more tasks and answer a series of questions involving the science processes of chemistry focused in the areas of Aqueous Solutions and Oxidation/Reduction.Ĭhemistry Lab is an event where participants must learn the year's selected aspects of chemistry and perform a lab or a set of labs regarding those topics.
