A gas occupies 15.2 L at 25 oC. The gas would expand to 30.4 L at _____ oC.  The pressure is held constant through the expansion. 

When considering polarity, the C-F bonds in CH2F2 are _____ and the molecule is _____.    

The spacing of lines in the microwave spectrum of 35Cl19F is 1.033 cm-1, what is the value of the rotational constant? In rotational spectroscopy of diatomic molecules (modeled as a rigid rotor), the wave numbers of the spectral lines are given by the formula: wavenumber = 2B(J+1), where J is the rotational quantum number of the lower state and B is the rotational constant.

Which element is NOT correctly matched with the block of the periodic table?

Which molecule is NOT polar?         I. HCN         II. CO2          III. SiF4  

A pressure of 7190 torr is the same as how many psi? 1 atm = 14.7 psi          760 mm Hg = 760 torr = 1 atm          2.54 cm = 1 in 

At constant temperature and pressure, how many L of CO2 are produced when 1.6 L of C4H4 completely react. C4H4(g) + 5 O2(g) –> 4 CO2(g)  +  2 H2O(g)  R = 0.08206
