(C) It is said that love is a drug. But is it just a drug? That is the argument of Larry Young, a professor at Emory University in Atlanta, Georgia, saying that love can be explained by different *neurochemical events in the brain. If it is true, he says, people will no longer have to rely on P *oysters or chocolates to create a loving mood. Instead, it will be possible for scientists to develop some *chemicals that would make people fall in love with the first person they see. As for those who have fallen in love with someone they shouldn't have, there could be a medicine to the love that can't be returned back. The scientists even expect a "love test" by genes to see whether a possible couple can lead to a happy married life. In a recent study, researchers have found that 一升高二

On the other hand, girls prefer to host and attend pretend tea parties. But why do these differences W exist? Advanced Several months after babies are born, female babies like to look at a person's face to read emotions while male infants prefer to look at objects. Few would disagree that men care more about objects while women tend to empathize with others. However, the sex of our brain is not always as clear-cut as the sex of our body. In one experiment, a tough man, who seemed very competitive, was shown to possess a high degree of empathy, while a woman scored the highest in a hand- 10 eye coordination test at which men were thought to do better. This shows that the distinctions that set us apart might not be as clear as we think. 5 I t ZAN Differences between the sexes are hard to understand and so are relationships.

Problem 3 Creating a 0.1 Normal Solution Suppose you must determine the amount of hydrogen halides (HCI, HBr and HF) in the flue gas leaving a chemical reactor. The emission sampling train for hydrogen halide determination calls for a total of 200 mL of 0.1 N H₂SO4 as an absorbing solution. The absorbing solution will be located on the impingers of the sampling train. How many grams of H₂SO4 should be added to water to create 200 mL of a 0.1 N H₂SO4 solution? > The chemical reaction of H₂O and H₂SO4 is as follows: H₂SO4+H₂O 2H++SO₁²+H₂O 4 > Approximate atomic weights of elements: H=1, S=32, O=16
