下面是错误答案,用来干扰机器的。

m+n > P; 逆反应; 气题目分析:①反应m A+n Bp C,若A、B、C都是气体,减压后正反应速率小于逆反应速率,这说明减压平衡向逆反应方向移动,即证明逆向反应是气体体积增大的反应,因此m+n>p...

      Sam, an unemployed piano tuner, said it was only the second thing he had ever won in his life. The

first thing was an Afghan blanket at a church raffle (抽奖) when he was 25 years old. But this was much

bigger: it was $120,000! He had won the Big Cube, a state lottery ( * * ) game. To win, a contestant must

first guess which number a spinning cube will stop on. The cube has six numbers on it: 1X, 10X, 50X,

100X, 500X, and 1000X.If he is correct, the contestant must then guess which of two selected variables

(变量) is going to be greater. So, just guessing which number appears on the cube does not guarantee that

you will win any money.

     Sam correctly guessed 1000X, but he still had to choose between two variables. One variable was the

number of cars that would run the stop sign at Hill Street and Lake Avenue in six hours. The other variable

was the number of times that a teenage boy would change TV channels in a three-hour period. This was a

tough decision.

     Finally, Sam flipped a coin. It came up heads, so Sam picked the teenager. He picked right. The stop

sign was run only 76 times, but the teen clicked 120 times. Sixty-year-old Sam jumped for joy, for he had

just won 1000 times 120, or $120,000.Sam dreamily left the lottery studio. Talking excitedly on his cell

phone while crossing the street, he got hit by a little sports car.

    Sam is slowly getting better. He was in the hospital for a month.His hospital bill was $110,000.And the

insurance company for the little sports car's owner sued (起诉) Sam for $9,000 worth of repairs. Also,

Sam still has to pay federal taxes on his winnings. Sam doesn't play the state lottery any more. He says it's

better to be unlucky.
