In a combustion reaction, pentane (molar mass (MM) = 72.17 g/mol) burns, in the presence of oxygen (MM = 32.00 g/mol), to produce carbon dioxide (MM = 44.01 g/mol) and water (MM = 18.02 g/mol).
The balanced reaction is shown here: C5H12 (l) + 8 O2 (g) Ã 5 CO2 (g) + 6 H2O (g)
If 160. g O2 is burned, what mass of CO2 is produced?
A.
138 g
B.
68.8 g
C.
264 g
D.
352 g

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
