Balance the following equations: a. AgI + Na2S → Ag2S + NaI

b. Na3PO4 + HCl →NaCl + H3PO4

c. Ba3N2 + H2O →Ba(OH)2 + NH3

d. TiCl4 + H2O →TiO2 + HCl

e. CaCl2 + Na3PO4 →Ca3(PO4)2 + NaCl

Ibeg i need 20. a reaction produces 4.93 l of oxygen, but was supposed to produce 1 mol of oxygen. what is the percent yield?

You have 125g of a certain seasoning and are told that it contains 76.0 g of salt what is the percentage of salt by mass in this seasoning

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?
