Chemical Reactions
Term | Definition |
---|---|
Activation Energy | what is needed to start a chemical reaction |
arrow | you read the arrow as "yeilds" in a chemical equation or formula |
characteristics of a chemical reaction | changes in energy or changes in properties (produce a gas(bubbles form) color change precipitate forms or temperature change) |
chemical changes | after the chemical properties of matter new substances with new properties are formed |
chemical equations | a shorter easier way to show chemical reactions by using symbols instead of words |
coeffecient | a number placed in front of a chemical formula in an equation. tells how many atoms or molecules of each reactant and product take part in the reaction |
conservation of mass | the amount of matter involved in a chemical reaction does not change the total mass of the reactants must equal the total mass of the products |
decomposition reaction | |
