You are working as an engineer at a food packaging plant. You have been assigned to work on a new packaging line for canned lemons. However, you know that lemons have a pH of 2.0. In one paragraph, using your own words, explain what this means, and what concept of chemistry leads you to believe that packaging lemons in cans might not be a good idea.

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)
