PLEASE HELPPP Given the following reaction: 2 K3PO4 + Al2(CO3)3 → 3 K2CO3 + 2 AIPO4
If I perform this reaction with 150 g of Potassium phosphate and 90 g of Aluminum
carbonate, what is my theoretical yield in grams of Potassium carbonate? What are my
limiting and excess reactants? If the reaction results in 125 g of Potassium carbonate,
what is my percent yield?
what are the excess reactants, what is the actual yield, what is the limiting reactant?

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?
