Types Of chemical Reactions
Two or more substances combining into a single substance
Synthesis
Process where atoms rearrange and new substances are made
Chemical Reaction
Substances that go into a chemical reaction
What are reactants
A chemical reaction where the reactants have more energy stored in their bonds than the products
what are exothermic reactions
Causes reaction rate to increase
What is an increase in concentration, surface area, temperature, or pressure
1 substance breaking down into 2 or more new substances
What is decomposition
Water becoming Ice
What is a physical change
Substance produced by a chemical reaction.
What are the products
A chemical reaction where products have MORE energy stored in their bonds than the reactants
Endothermic
What type of reaction is this?
NaCl+AgNO3 -> NaNO3+ AgCl
Double Replacement
1 element replacing another in a compund
What is single replacement
Matter cannot be created or destroyed and the number of atoms are the same before and after a chemical reaction.
What is the law of Conservation of Mass
The number in front of a substance in a chemical equation
When chemical bonds form they ______ energy
Release
Dynamite exploding
What is a combustion reaction
A reaction that always has oxygen as a reactant and also commonly produces water and carbon dioxide as products
What is combustion
An example of physical change
Being crushed or broken up, being melted, frozen, evaporated
A substance made of multiple elements
What is a compound
The amount of energy necessary to break the initial chemical bonds and start the reaction
Activation Energy
A substance that slows or stops a chemical reaction
what is an inhibitor
When two negative ions are traded between two compounds
What is double replacement reaction
At least 3 signs of a chemical reaction occurring
What are changes in color, odor, a precipitate forming, bubbles forming, temperature change
Usually means "yields" or "produces".
What is the arrow
Increases the reaction rate by lowering activation energy
Catalyst
DAILY DOUBLE
Balance the following equation
FeO+O2 ->Fe2O3
4FeO+O2->2Fe2O3
