Molecular compounds are usually exceptions to the law of definite proportions composed of two or more transition elements composed of two or more nonmetallic elements composed of positive and negative ions

Which of the dna typing techniques do you think you would choose if you had to analyze a dna sample? why?

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?

Is the flow of energy during vaporizing more like the flow during melting or during freezing
