In a oxidation-reduction reaction, the oxidizing agent is:

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)   

According to the chemical naming system, which name is incorrect? Formula:                 Name: SnCl4              tin (IV) chloride SO2                       sulfur dioxide Mg(CO3)         magnesium carbonate Na2(SO4)        disodium sulfate FeBr2              iron (II) bromide  

The correct name for Na2O is

According to the chemical naming system, which name is incorrect? Formula:                 Name: SnCl4              tin (IV) chloride S2Cl2                    disulfur dichloride Mg(CO3)         magnesium carbonate Na2(SO4)        sodium sulfate FeBr2              iron bromide  

Experiments by Gay-Lussac showed that the pressure of a gas at a constant volume:

When sulfur (S, #16) forms an ion in an ionic compound, it would be represented by  a. S+2     b. S-2     c. S+6     d. S-6

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

The direct change from the solid state to the vapor state is called

Use the equations below to solve the following gas law problem.  P1V1T2 = P2V2T1                          1 atm = 760 mm Hg = 760 torr A 0.823 L sample of carbon dioxide, initially at 0.25 atm of pressure is compressed until it occupies only 93.2 ml.  If temperature remains constant, what is the final pressure, in mm Hg, of the gas? To receive full credit:  You must use the math equation editor in the tool bar to insert the final gas law equation (with numbers and units) that you used to solve the problem.  Be sure to include the answer. Or, show your work on a separate sheet of paper and submit in the Unit 2 Exam pictures dropbox after completing the Exam.
