6. Among the substances that react with oxygen and that have been considered as potential rocket fuels are diborane Bho, produces B2O3(s) and H2O(g)], methane (CH4, produces CO2(g) and H2O(g)], and
hydrazine N2H4, produces N2(g) and H2O(g)]. On the basis of the heat released by 1.00 g of each
substance in its reaction with oxygen, which of these compounds offers the best possibility as a rocket fuel?
The AH; of B2H6(g), CH4(g), and N2H4(1) may be found in Appendix G.

When water dissociates, each water molecule splits into a hydroxide ion and a) h 3 o + b) a hydrogen atom c) a hydrogen ion d) h 2 o e) oh —

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?

How might this scientific phenomena be explained? a paper clip floats on water.
