Endo/Exo Flashcards
(7 cards)
1
Q
Exothermic
A
-Energy of the reactants is greater than the energy in the products.
-Energy is released
2
Q
endothermic
A
-energy of reactants is less than energy in the products
-Energy is absorbed
3
Q
Combustion
A
-Oxygen burns a substance
-light and heat (energy are produced)
4
Q
corrosion
A
-Metals combine with oxygen
-metal oxides are produced
5
Q
Decomposition reaction
A
-when a single reactant breaks apart to form multiple products
e.g H2CO3 –> H2O + CO2
6
Q
Combination reactions
A
-When 2 reactants combine to for a single product
e.g 2h2 +o2 –> 2H2O
7
Q
Precipitation reactions
A
-A reaction where 2 soluble products combine to form at least 1 insoluble product.
