To classify as click, a reaction has to adhere to a set of extensive and stringent criteria including being insensitive to oxygen and water, taking place in no or benign solvents, being stereospecific and selective for a single product that requires no chromatography to isolate, and having a th...
What happens during a chemical reaction between two compounds? How are metallic minerals formed? How were the synthetic elements discovered? What are atoms and elements, and how do they differ? How do you classify chemical reactions? What happens to atoms in a chemical reaction?
In organic chemistry, how do you determine the strength of bases based on their structure? Identify the acids and bases in the given reaction: How is an acid different from a base? Identify as an acid or a base. Provide a chemical equation showing how this is an acid or a base accordin...
How does mass change during a chemical reaction? Building Blocks Of Matter: All matter is made up of tiny building blocks called atoms. Atoms are bonded together to form molecules and compounds, which make up everything that exists in the universe. The amount of matter in a substance is dir...
Chemists classify all matter into three groups: elements, compounds and mixtures. An element, such as carbon, hydrogen or oxygen, can't be broken down into other substances. A compound happens when two or more elements join chemically in a definite proportion. ...
EVIDENCE of a CHEMICAL REACTION (aka a CHEMICAL CHANGE) a GAS is produced a TEMPERATURE change These chemical reactions RELEASE heat! Sodium (Na) in water: 2 Na + 2 H2O 2 NaOH + H2 + BOOM http://www.youtube.com/watch?v=92Mfric7JUc ...
BASE a class of compounds that taste bitter, feel slippery in water soln., turn red litmus to blue, and react with acids to form salts ORGANIC COMPOUNDS covalent compounds containing carbon (except carbonates and oxides) INORGANIC COMPOUNDS compounds outside the organic family of compounds ...
We choose to examine students’ understanding of matter and energy in concert for a number of reasons. Although energy is not an object or a substance, it must be identified by its association with objects and substances or changes in objects or substances. In much of K-12 chemistry, the ...
(b) How are properties of a compound related to elements that comprise it? Chemical Reactions: In a synthesis reaction, two or more substances called "reactants" combine to form a single "product" substance. In decomposition reactions, a sing...
What are the six strongest acids in general chemistry? Classify each of the following as a strong acid or a weak acid. What is the definition of a weak acid? Predict the acid strength of the following compounds: H2O, H2S, and H2Se. ...
