Chemical Reactions Flashcards
Chemical Equation is?
number of atoms of each element same for reactants and products
Chemical reactions are?
reactants or starting materials making or breaking chemical bonds to form a new substance or product from another
Synthesis is?
smaller molecules forming larger molecules
A+B= AB is an example of?
anabolic process (amino acid1 + amino acid2 = peptide protein
AB = A+B is an example of?
catabolic process (glycogen= glucose+glucose+glucose….)
Decomposition is?
larger molecules being broken down into smaller molecules
Displacement is?
one part is exchanged
double displacement is ?
more than one exchanged. AB+CD=AC+BD
energy released during a reaction is?
Energonic ……A+B=C+D+energy
energy required for a reaction to proceed is?
Endergonic A+B+energy= C
Exerthermic releases _________?
Heat
Endothermic ___________?
adds heat
A+B >AB & AB >A+B is
a reversible reaction
A+B<>AB
Chemical equilibrium
In terms of chemical reaction rates, the size of reactants means
smaller is faster
In terms of chemical reaction rates temperature means
speeds up particles
In terms of chemical reaction rates concentration means
particles more likely to come together and react
In terms of chemical reaction rates catalysts or enzymes mean?
makes a reaction more convenient
in a beaker of water the ratio of Hydrogen ions to H2O is about
