2. The skeletal structure of acetic acid shown below is correct, but some of the bonds are wrong. H:O: H=C-C-0-H H a. Identify the incorrect bonds and explain what is wrong with them. b. Write the correct Lewis structure for acetic acid.

hat does temperature measure? Are the molecules in a beaker of warm water moving at the same speed as the molecules in a beaker of cold water? Explain? What is heat? Is heat the same as temperature?

Methanol, H3COH, is used as the fuel in some race cars. Ethanol, C2H5OH, is used extensively as motor fuel in Brazil. Both methanol and ethanol produce CO2 and H2O when they burn. Write the chemical equations for these combustion reactions using Lewis structures instead of chemical formulas.

Rank the elements or compounds in the table below in decreasing order of their boiling points. That is, choose 1 next to the substance with the highest boiling point, choose 2 next to the substance with the next highest boiling point, and so on. substance A B C D chemical symbol, chemical formula or Lewis structure .. 0=N-C1: : Cl : : Cl: CaCl₂2 ..
