Types of Chemical Reactions

Synthesis Reaction ~ When two are combined to make one.

Synthesis Reaction ~ When two are combined to make one.A + B --> C

Synthesis Reaction ~ When two are combined to make one.A + B --> C

2H2(g) + O2(g) --> 2H2O(g)

Synthesis Reaction ~ When two are combined to make one.A + B = C

2H2(g) + O2(g) = 2H2O(g)Despite what the book says, the above reaction does NOT power rockets.

Synthesis Reaction ~ When two are combined to make one.A + B = C

2H2(g) + O2(g) = 2H2O(g)Despite what the book says, the above reaction does NOT power rockets.2H2(l) + O2(l) = 2H2O(g) This one does

Synthesis Reaction ~ When two are combined to make one.A + B = C

Fe + O2 --> Fe2O3

Synthesis Reaction ~ When two are combined to make one.A + B = C

Fe + O2 --> Fe2O3

4Fe + 3O2 --> 2Fe2O3

Decomposition Reaction ~ When one comes apart to make two.

Decomposition Reaction ~ When one comes apart to make two.

AB --> A + B

Decomposition Reaction ~ When one comes apart to make two.

AB --> A + B

2H2O2(l) ---> 2H2O(l) + O2(g)

Decomposition Reaction ~ When one comes apart to make two.

AB --> A + B

2H2O2(l) ---> 2H2O(l) + O2(g)2Fe2O3 --> 4Fe + 3O2

Displacement Reactions ~ when one or two things take the place of some others.

Single Replacement ~

A + BC --> AC + B

Displacement Reactions ~ when one or two things take the place of some others.

Single Replacement ~

A + BC --> AC + B

Displacement Reactions ~ when one or two things take the place of some others.

Single Replacement ~

A + BC --> AC + B

HCl + Al ---> H2 + AlCl3

Displacement Reactions ~ when one or two things take the place of some others.

Single Replacement ~

A + BC --> AC + B

HCl + Al ---> H2 + AlCl36HCl + 2Al ---> 3H2 + 2AlCl3

Displacement Reactions ~ when one or two things take the place of some others.

Double Replacement ~ two things trade places

AB + CD --> AD + CBBa(NO3)2 + K2(SO4) --> Ba(SO4) + 2K(NO3)

Displacement Reactions ~ when one or two things take the place of some others.

Double Replacement ~ two things trade places

AB + CD --> AD + CBBa(NO3)2 + K2(SO4) --> Ba(SO4) + 2K(NO3)

Ba(NO3)2 + K2(SO4) --> Ba(SO4) + 2K(NO3)

Exothermic reaction gives off heat. “Exo” means out. Basically a fire.

Exothermic reaction gives off heat. “Exo” means out. Basically a fire.Endothermic reaction absorbs heat from the environment. Basically a cold pack.

Exothermic reaction gives off heat. “Exo” means out. Basically a fire.Endothermic reaction absorbs heat from the environment. Basically a cold pack.To speed up a reaction, use a catalyst.Inhibitor would be something that slows down a reaction, or a gets in the way of human endeavor. Like saying he “inhibits” our work in science class, maybe …..?
