Aluminum hydroxide (Al(OH ) 3) is often present in antacids to neutralize stomach acid (HCl). The reaction occurs as follows: Al(OH ) 3(s) + 3HCl(aq) AlC l 3(aq) + 3 H 2O(l). If 14.0 g of Al(OH ) 3 is present in an antacid tablet, determine the theoretical yield of AlC l 3 produced when the tablet r

A number of amusement parks have rides that make vertical loops like the one shown in Figure 6.33. For safety, the cars are attached to the rails in such a way that they cannot fall off. If the car goes over the top at just the right speed, gravity alone will supply the centripetal force. What other
