Studied by 2 people
Chemical reaction
When chemical bonds break or form
Precipitate
A solid that can appear during chemical reactions
Endothermic reaction
When energy is absorbed, temp drops
Exothermic reaction
When energy is released, temp rises
Subscripts
The small numbers that determine ratios
Coefficients
The big numbers in front of formulas, multiplies small numbers
Chemical equation
Shows chemical reactions
Reactant
Part of a chemical equation, the part that gets changed
Product
Part of a chemical equation, what you get from reaction
Yield
The arrow in chemical equations
Synthesis
Two or more substances combining to make a more complex thing
Decomposition
Breaks down into simpler products
Replacement
One element replaces another
Activation energy
The boost of energy to get chemical reactions started
Concentration
The amount of matter together, how close or apart
Catalyst
Material increasing rate of chemical reaction
Inhibitor
Material decreasing rate of chemical reaction
Enzymes
Substance produced by living organism for a biochemical reaction
Conservation of mass
Mass cannot be created or destroyed
Formula mass
Number of atoms times atomic mass= formula mass
Evidence of chemical reaction
Change in energy, temperature, production of gas, production of precipitate, color change
Exothermic activation energy memory clue
Exothermic just needs to let it all out
Endothermic activation energy
Needs energy to keep going
Exothermic activation energy
Does not need energy to keep going
