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?   

On a separate sheet of paper, draw the Lewis dot structure for NF3.  After completing the exam, upload your picture in the Unit 2 Exam pictures dropbox. 

Balance the equation below by placing the correct coefficients in the blanks. Your response should list the coefficients in order from left to right, separated only by commas; no spaces. If no coefficient belongs in a blank, represent it with a “1”. For example the equation 2 H2O →  2 H2 +O2 would be represented as 2,2,1.____Cr + ____H2(SO4)  →  _____H2 +   ____Cr2(SO4)3 

Which of the following has NOT been offered as evidence for a biological basis for sexual orientation?

Risk taking is increased when choice scenarios are discussed in terms of:

Determine the oxidation number of the underlined element in the following compound. Be sure to indicate if the oxidation number is positive or negative. CaCO4

Balance the equation below by placing the correct coefficients in the blanks. Your response should list the coefficients in order from left to right, separated only by commas; no spaces. If no coefficient belongs in a blank, represent it with a “1”. For example the equation 2 H2O  → 2 H2+O2 would be represented as 2,2,1.   ____H3(PO4)  + ____ Rb(OH) →   ____H2O + ____Rb3 (PO4) 

On a separate sheet of paper, draw the Lewis dot structure for (CO3)-2. After completing the exam, upload your picture in the Unit 2 Exam pictures dropbox.

During lecture, Jamie was on-line shopping, Dakota was on Facebook, Emerson was filling out an NCAA bracket, Ashton was swiping on tinder, and Kai was watching soccer. Jamie, Dakota, Emerson, Ashton, and Kai all tell themselves that they “need mental breaks from lecture” so that they can really focus on the material once they have finished their activities. According to psychodynamic theory this represents an example of ________.
