The San Andreas Fault is a transform fault

The softest mineral on Mohs’ hardness scale is ____. 

Hess’s original hypothesis was that sea-floor spreading is driven by deep mantle ____. 

The head of large plumes that form “hot spots” may cause uplift and ____. 

When seawater evaporates, its sodium and chlorine are electronically attracted to one another and crystallize into ___.       

Write a balanced chemical equation for the following combustion reactions.  (2 marks each) a)  The complete combustion of 2-butanol, C4H10O b) The incomplete combustion of butane, C4H10 (Hint: For balancing, the coefficient in front of the oxygen gas reactant will be 4 and the products will be H2O, CO2, CO, and C)

It is important to handle and store organic compounds, such as ethers, carefully because:

One of the main reasons that there are so many different organic compounds is:

The temperature-time graph above represents the distillation of a mixture of unknown alcohols and water. Explain how you can use a temperature-time graph of a distillation to determine what compounds are present in an unknown mixture.  (3 marks)

Consider the following pairs of reactants which will be mixed in solution: a)  K2S(aq)  +  CaBr2(aq)  –> b)  KOH(aq)  +  BaCl2(aq)  –> c)  Na3PO4(aq)  +  AgNO3(aq)  –> If the products include a precipitate, write the balanced chemical equation for the reaction (including all subscripts). If no precipitate will form write “no precipitate” after the reaction arrow.      (8 marks)
