1 The equations below show four processes that use water as a starting material. (4-6)
A: H20, → H2O
B: 21,0 + 2Nao → 2NaOH(aq + H26)
C: H20, → +H20) D: 24,0 → 2H260) + O2(8)
a) State which equation shows evaporation.

If a solution had a ph of 7 what is the solution

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?
