Based on the cations identified in the question above, determine if the painting in question was a forgery. Explain how you were able to determine if the painting was a forgery. Indicate which pigments were likely in the unknown and when they were likely used. Note that each cation itself is not a pigment; the full chemical formula for each pigment can be found in the Pigment Handbook in your lab manual.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
