PHYSICS

• Compound

  Consist of 2 or more elements combined together
• BINARY COMPOUND

  • Made of two element
• Binary compound

  CO2 - Carbon Dioxide

  NaCI- Sodium Chloride
• 2 TYPES OF BINARY COMPOUND

  1. IONIC COMPOUND
  2. MOLECULAR COMPOUND
• IONIC COMPOUND

  • Made of cation and anion
  • They are named by giving the name of the cation first, followed by the name of anion
• IONIC COMPOUND

  Nal - Sodium Chloride

  MgCl2- Magnesium Chloride

  FeS - Iron (ll) Sulfide

  K2O - Potassium Oxide
• MOLECULAR COMPOUND

  -Made of two non-metals. They are usually gasses
• MOLECULAR COMPOUND

  -They are named by giving the name of the first non metal and then that of the second non metal modified by the ending- ide
• MOLECULAR COMPOUND

  HCI - Hydrogen Chloride

  CO2 - Carbon Dioxide

  SO3 - Sulfur Trioxide
• 2 DIVISION OF COMPOUND

  1. BINARY COMPOUND
  2. TERNARY COMPOUND
• TERNARY COMPOUND

  -Made of Three elements
• TERNARY COMPOUND

  C6H12O6- GLUCOSE

  NaNO3 - SODIUM NITRATE
• ACIDS

  -Yields Hydrogen ions in aqueous solution.
• 2 TYPES OF ACIDS

  1.BINARY ACIDS

  2TERNARY ACIDS
• BINARY ACIDS

  -Compound of hydrogen and another element, usually non metal
• BINARY ACIDS

  The first part of the name starts with prefix hydro followed by the name of the element, modified by the ending- ic

  The second part consists of the word / acid/. To put it simply, name =hydro- (root name of the element) - ic + acid
• BINARY ACIDS

  HCI - Hydrochloric Acid

  HI - Hydroiodic Acid
• TERNARY ACIDS

  -Made of hydrogen and anion,usually containing oxygen.
• TERNARY ACIDS

  -The first part of the name consists of the root word of the name of the element, modified by the ending -ic. or ending- ous if there is another acid on the set of example with the same atom, to denote the one with less number of atoms.

  The second part consists of the word /acid/. To put it simply, name=(root name of element )-ic (or- ous) + acid
• TERNARY ACIDS

  HNO3 - Nitric Acid

  HNO 2 - Nitrous acid
• CHEMICAL REACTION

  A process in which one or more substances, the reactants , are converted to one or more different substances, the products

  Substances are either chemical elements or compounds.

  A Chemical reaction rearranges the constituent atoms of the reactants to create different substances as products
• 5 TYPES OF CHEMICAL REACTIONS

  1. Decomposition Reaction
  2. Synthesis Reaction
  3. Single Displacement Reaction
  4. Double Displacement Reaction
  5. Combustion Reaction
• Decomposition Reaction

  -a reactant breaks down into 2 or more products
• Synthesis Reaction

  • 2 or more reactants form a single product.
• Single Displacement Reaction

  • one element replaces another in a compound
• Double Displacement Reaction

  • 2 ionic compouncompounds exchanging ions.
• Combustion Reaction

  • a hydrocarbon (a compound containing hydrogen and carbon) reacts with oxygen to form heat, carbon dioxide and water.
• TYPES AND EVIDENCES THAT A CHEMICAL REACTION HAS OCCURRED

  A)change in color

  B)formation of a solid (a

  precipitate)

  C)Evolution of Gas (Bubble formation)

  D) Change in temperature (heat is released or absorbed)
• DALTON'S ATOMIC THEORY

  • Proposed by John Dalton
  • Can be used to explain the laws of chemical change.
• ACCORDING TO DALTON

  • Elements are made up of very small particles known as atoms.
  • All the atoms of an elements are identical in mass and size
