When NaNO3 is mixed with PbO2 it forms Pb(NO3), and Nazo. We start the reaction having 22.2 g of sodium nitrate and 46.4 g of lead (IV) oxide.
How many grams of sodium oxide can be produced in this reaction?

There are main groups in the modern periodic table of elements

Stage in which a typical star has completely stopped fusion

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?
