What is a major difference between inorganic and organic compounds? - ANSWER Organic compounds contain carbon; few inorganic compounds do. Identify the correct statement: The alkanes represent one family of organic compounds - ANSWER that is composed of carbon and hydrogen. Which of the following is an alcohol? - ANSWER CH3CH2OH

Hydrocarbons - Answer Covalent compounds containing only hydrogen and carbon atoms Alkanes - Answer Saturated Hydrocarbons Alkenes - Answer Unsaturated hydrocarbons containing a double bond. Unsaturated Hydrocarbon Test - Answer Add hydrocarbon to bromine water. Colour goes from brown to colourless. Addition of Hydrogen - Answer Alkene + Hydrogen → Alkane. Requires temperature of 150°C and a Pt or Ni catalyst. Addition of Halogen - Answer Alkene + Halogen (e.g. Bro...

fuel any solid, liquid, or gaseous substance that may be combusted (burned) to produce heat or work Fuel characteristics - ignites easily at a low temperature - produces a large quantity of heat during combustion - inexpensively isolated - has properties that allow for their safe/efficient storage or transport - leaves little residue behind after being burned - produces by-products that are not harmful to human health of the environment Brainpower Read More Previous Pla...
