2. Several reactions are carried out using Pbl2, a
bright yellow lead salt for
which the value of the
solubility-product constant,
Ksp, is 1.4 x 10-8 at 298 K.
Write the expression for the
solubility-product constant,
Ksp, of Pbl2

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

*will mark you brainliest + 15 points ** why does the equilibrium of a system shift when the pressure is increased? a. to maximize the stress on the system b. to stop restoring equilibrium to the system c. to increase the total moles of gas in the system d. to decrease the total moles of gas in the system

Jose and eric were given four samples in lab. the results of their analysis are shown in the table. based on the data they collected, which sample is most likely a metal?
