Write the net ionic equation for the reaction that occurs when an aqueous solution of hydrochloric acid reacts with an aqueous solution of ammonia.and find delta H
at 400K and a total pressure of 1.0atm, the mole fraction of H2 is 0.25 and that of I2 is 0.30, in equilibrium with HI. Calculate Kp and Kc for the equilibrium.
Silver metal reacts with chlorine to yield silver chloride. If 2.00 g of Ag reacts with 0.657 g of Cl2, what is the empirical formula of silver chloride? please break this down. I have the answer as AgCl but have no clue on how to get there, again..
for each of the three types of polarization,briefly describe the mechanism by which dipoles are induced and/or oriented by the action of an applied electric field. For solid lead titanate, gaseous neon, diamond
Find the equilibrium concentrations of \rm A and {\rm B} for a = 1 and b = 2. Assume that the initial concentration of \rm A is 1.0 {\rm M} and that no {\rm B} is present at the beginning of the reaction. kc=2.3
