PASSSSSSSSSS
States that the amount of substance is directly proportional to volume, provided that temperature and pressure remain constant
Avogadro’s Law
Avogadro’s law equals to
6.022x10^23
one of the major macromolecules which provides energy for our muscles and fuel our brain
Carbohyrate
breaks down carbohydrate during the process of ____ to release energy
Metabolism
How do lipids function for cells
Store energy
molecules that make up carbohydrates
Carbon, hydrogen, oxygen
_____ are macromolecules made up of amino acids
Protein
building blocks of carbohydrates
Monosaccharides
contains carbon, hydrogen, oxygen, nitrogen, and are found in all living beings
Nucleic acids
They are linear macromolecules formed by the polymerization of units called ___
Nucleotides
Is a process in which one or more substances, also called reactants are converted to one or more different substances
Chemical reaction
where are reactants located
Left side
Evidences of occurences of chemical reaction (5)
Color changes, Temperature changes, Precipitates, Light emission, Gas Production
A white sheet of paper turning into ashes after being burned
Color changes
Exothermic reactions give off heat while endothermic reactions absorb heat
Temperature changes
A precipitate is an insoluble liquid that emerges from a liquid solution
Precipitates
is a rapid chemical reaction of a subtance with oxygen
Combustion
production of heat and light
LigHT EMMISION
The electrolysis of water for example is a decomposition reaction that breaks water into hydrogen and oxygen gas
Gas Productionis a substances used up during a chemical reaction
is a substance formed after a chemical reaction
Product
used to separate one reactant or product from another
+
Used to separate the reactants from the products - it is pronounced as yields or produces when the equation is read
—–>
used when the reaction can proceed in both direction, this is called an equilibrium flow
<——-
——–>
a REACTION when 2 or more reactants combine to form a single product
Combination Reaction
General formula for combination reaction
A + B —> AB
In this reaction, a single reactant breaks down simpler ones (2 or more products) opposite of combination
Decomposition reaction
General formula for decomp reaction
AB —-> A + B
When one element replaces another element from another compound
Single displacement reaction
General formula for single displacement reaction
A + B —-> AC + B
When positive ions (cations) and negative ions (anions) of different compounds switch places, forming two entirely different compounds
AB + CD —> AD + CB
wHEN oxygen combines with a hydrocarbon
combustion reaction
A special kind of double displacement reaction that takes place when an acid and base react with eachother
Acid-base reaction
change in size
Physical change
change in texture
CHEMICAL CHANGE
is neither created or destroyed
matter
