Questions and Answers

What is a precipitate?

An insoluble compound that comes out of the solution.

Describe the characteristics of the five types of chemical reactions.

1.) Synthesis: 2 or more reactants combine to make 1 product. 2.) Decomposition: When 1 reactant breaks down into 2 or more products. 3.) Combustion: When something is burned, with oxygen (O2) as a reactant and carbon dioxide (CO2) and water (H2O) as products. 4.) Single Replacement: One element replaces a similar element in a compound. 5.) Double Replacement: Two ionic compound reactants switch ions, forming two new ionic compound products, usually resulting in a precipitate.

Study Notes

Precipitation

  • Precipitate refers to an insoluble compound that emerges from a solution.

Types of Chemical Reactions

  • Synthesis: Involves two or more reactants combining to form a single product.
  • Decomposition: A single reactant breaks down into two or more products.
  • Combustion: A reaction where a substance is burned, always involving oxygen (O2) as a reactant and producing carbon dioxide (CO2) and water (H2O) as products.
  • Single Replacement: One element in a compound is replaced by a similar element from another compound.
  • Double Replacement: Two ionic compounds react and exchange ions, typically resulting in the formation of a precipitate.

Reaction Classifications

  • Double Replacement: AlBr3 + K2SO4 = KBr + Al2(SO4)3.
  • Synthesis: Al + O2 = Al2O3.
  • Single Replacement: LiCl + Br2 = LiBr + Cl2.
  • Decomposition: NF3 = N2 + F2.
  • Combustion: C4H10 + O2 = CO2 + H2O.
  • Double Replacement: Pb(OH)2 + HCl = H2O + PbCl2.

Reaction Balancing and Classification

  • Synthesis Reaction: 3S + 2Fe = Fe2S3 (Solid sulfur reacts with solid iron to form solid iron (III) sulfide).
  • Single Replacement Reaction: 3H2 + Fe2O3 = 3H2O + 2Fe (Hydrogen gas reacts with iron (III) oxide to produce water and iron powder).
  • Combustion Reaction: C3H8 + 5O2 = 3CO2 + 4H2O (C3H8 is burned).
