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

Suppose dwelling quality is measured on a scale of 1 to 10, and the monthly cost of producing a particular quality equals the square of the quality level: For quality level 1, the cost is $1; for quality level 2, the cost is $4, and so on. The monthly rent equals the price per unit of quality (P= $9)
