     Michelle Katz is a health-care saving expert with a master's degree in nursing,so when her husband

Martin had a heart attack right in front of her,she fought to save his life. Then,she fought the errors on his

medical bill and saved the

couple $ 7,000.

       Kaze was talking with her husband in June 2008 when she noticed his face tuming gray. "I looked

over and I said,Martin,are you OK?'"she told Good Morning America. "If I can describe death,that's

kind of what I was seeing.  And that's when I grabbed him.  And as I grabbed his hand,it was almost like

putting my hand in a vat (桶)  of ice cubes.It was that cold. He started stiffening up. "

      Terrified,Katz immediately gave her husband CPR.

       "I started pushing down on the compressions (压缩) and was just screaming and saying'Are you

OK? Are you still with me ? '"she said. "I just wanted him to know,even if he wasn't listening,that I was

not going to let someone die in my hands. And especially _____ "

        Later,X-rays showed that Katz had cracked her husband's ribs (肋骨)  with the force of her

compressions.  After 16 long minutes,an ambulance arrived and took Martin to the emergency room.

      When hospital took over,Katz,the author of two books about saving money on medical bills,started

paying attention. She swore to follow the advice she had given others in Healthcare for Less and 101

Health Insurance Tips.

         "I knew the dollar signs were going up, " Katz said. "That's when I started documenting things. "In

the days that followed,Katz found errors on the bills that,when correctedlsaved her and her husband $

7,000.

在T℃时，向1 L固定体积的密闭容器M中加入2 mol X和1 mol Y，发生如下反应：2X(g)＋Y(g) aZ(g)＋W(g) ΔH＝－Q kJ/mol(Q＞0)；该反应达到平衡后，放出的热量为Q₁ kJ，物质X的转化率为α；若平衡后再升高温度，混合气体的平均相对分子质量减小。

请回答下列问题：

(1)化学计量数a的值为________。

(2)下列能说明该反应达到了化学平衡状态的是________(填序号)。

a．容器内压强一定

b．容器内气体的密度一定

c．容器内Z的分子数一定

d．容器内气体的质量一定

(3)维持T℃温度不变，若起始时向容器M中加入2 mol X、1 mol Y和1 mol Ar(稀有气体不参与反应)，则反应达到平衡后放出的热量是________kJ。

(4)维持T℃温度不变，若在一个和原容器体积相等的恒压容器N中加入2 mol X和1 mol Y，发生题给反应并达到平衡，则________(填“M”或“N”)容器中的反应先达到平衡状态，容器中X的质量分数M________N(填“＞”、“＜”或“＝”)。

(5)已知：该反应的平衡常数随温度的变化情况如表所示：

若在某温度下，2 mol X和1 mol Y在容器M中反应并达到平衡，X的平衡转化率为50%，则该温度为________℃。

(6)维持T℃温度不变，若起始时向容器M中加入4 mol X和6 mol Y，反应达到平衡时容器内的分子数目减少10%，则反应中放出的热量为________kJ。
