Suppose that Arthur lives in New York City, his friend Scott lives in a much smaller city about 40 miles north of New York City, and his other friend, Josh, lives in another small city about 40 miles south of New York City. One weekend, Josh decides to drive from his home to Arthur’s home and then on to Scott’s home. According to the landmark effect, which leg of the trip would most likely seem longer?

A sample containing 21.03 mol of magnesium has a mass of _________ g.

Tetraphosphorous hexaoxide is formed by the reaction of phosphorous (P4) with oxygen gas. P4 (s) + 3 O2 (g) –> P4O6 (s) If the reaction of 68.8 g of P4 with 18.8 g of O2 produces 21.0 g of P4O6, calculate the percent yield for the reaction. ​
