synthesis reactions
|
when two or more atoms, ions, or molecules combine to form new and larger molecules (synthesis=to put together)
|
|
|
How can a synthesis reaction be expressed?
|
A + B -> AB
Atom, ion or molecule A + Atom, ion, or molecule B -> (combine to form) new molecule AB |
|
|
Name an example of a synthesis reaction.
|
the reaction between two hydrogen molecules and one oxygen molecule to form two molecules of water
H2 + O2 -> H2O |
|
|
All the synthesis reactions that occur in your body are collectively referred to as _____________________.
|
anabolism - building up(endergonic because they absorb more energy than they release)
|
|
|
Decomposition reactions
|
split up large molecules into smaller atoms, ions, or molecules (catabolism)
|
|
|
How can a decomposition reaction be expressed?
|
AB -> A + B
molecules AB -> breaks down into Atom, ion, or molecule A + atom, ion, or molecule B |
|
|
Decompostion reactions that occur in your body are collectively referred to as _____________________.
|
catabolism - breaking down (exergonic because they release more energy than they absorb)
|
|
|
exchange reactions
|
consist of both synthesis and decomposition reactions
|
|
|
How can an exchange reaction be expressed?
|
AB + CD -> AD + BC
bonds between A and B and between C and D break and new bonds form between A and D and between B and C |
|
|
Give an example of an exchange reaction.
|
HCl + NaHCO3 -> H2CO3 + NaCl
Hydrochloric acid + Sodium bicarbonate -> Carbonic acid + Sodium chloride |
|
|
What is oxidation?
|
The loss of electrons from a molecule
|
|
|
reversible reaction
|
in a reversible reaction, the products can revert to the original reactants
|
|
|
How is a reversible reaction indicated?
|
two half arrows pointing in opposite directions
AB <=====> A + B AB breaks down into -> / or combines to form <- A + B |
|
|
True or False?
Some reactions are reversible only under special conditions. |
True. AB <===> A + B
--> water; <-- heat |
