Use the factor-label method to solve the following stoichiometry problem.   Given the following equation: 1 C3H8  +  5 O2    3 CO2  +  4 H2O How many moles of oxygen are required to react with 25.4 grams of C3H8? To receive full credit:  You must use the factor unit method and the math equation editor in the tool bar to insert the stoichiometric calculation.  Show your work (conversion factors/and units) by using the equation editor () in the toolbar.  If necessary, use the the three vertical dots to expand the toolbar. Within the equation editor, use    to insert conversion factors. Be sure to include proper units and the final answer! Or, show your work on a separate sheet of paper and submit in the Unit 2 Exam pictures dropbox after completing the Exam. 

Determine the oxidation number of the underlined element in the following ion. Be sure to indicate if the oxidation number is positive or negative. (HPO3)-1  

Refer to the structural formula given below:  Is this molecule polar or nonpolar? 

According to Eysenck:

Use the factor-label method to solve the following stoichiometry problem.   Given the following equation: 1 C3H8  +  5 O2    3 CO2  +  4 H2O If 9.21 x 1024 molecules of water are produced from this reaction, what mass of CO2 is produced?

A motivation of which we are aware is a(n):

Assign oxidation numbers to each element in the following reaction. Write the oxidation number of the individual element in the box beside the element.  In the case of the compounds, write the oxidation number of the first element in the first box and the oxidation number of the second element in the second box. Then identify the element oxidized and the reducing agent.  I-1 [a1] + (MnO4)-1 [a2] , [a3]   I2 [a4]    +  MnO2 [a5], [a6] What is the element oxidized? [a7] What is the reducing agent? [a8]

Refer to the structural formula given below:  What type of intermolecular forces (dipolar, dispersion, or hydrogen bonding) would exist between molecules of PCl3?
