2．（2025 吉州区校级模拟）
The Silent Signal
In a quiet little town in England，there lived an elderly man named Harold.Uneducated and widowed（鳏夫），Harold's heart was heavy with loneliness.His children，Emily，a doctor in London，and Thomas，a lawyer in Manchester，had moved to the busy cities，leaving him in the family home with only his old mobile phone for company.The phone was a lifeline to his children，and he treasured every ring.
One day，Harold decided to visit a local mobile phone repair shop，TechSolutions，with a sense of urgency.His phone，an outdated one，had been silent for weeks.No calls，no messages﹣just a terrible quiet that seemed to mirror his life.
Harold entered the shop，with his pace slow and tired.He approached the counter and handed his phone to the young repairman，a cheerful man named Liam."There's something wrong with it，"Harold insisted，his voice trembling slightly."It's not ringing，and I'm sure my children，Emily and Thomas，want to speak to me."
Liam，with a warm smile，took the phone and began to inspect it.Harold watched and held his breath as Liam pressed buttons and shook his head，saying technical terms under his breath.After a few minutes，Liam looked up and announced，"Everything seems to be in order，Mr.Harold.Your phone is functioning perfectly."The news did not bring relief to Harold's wrinkled forehead.If anything，his worry lines deepened."But if it's working，why haven't I received any calls？"he asked，his voice barely above a whisper.

而不是NaOH,工业上是电解熔融MgCl2制取Mg,而不是电解MgO;向NaCl溶液中通入CO2,不符合强酸制
弱酸的原理，不会发生反应生成NaHCO,工业上是向饱和NaCI溶液中先通入NH3,再通人CO2制取
NaHCO3。
7.D【解析】反应①中，Mn元素的化合价由十7降低为十4，H2O2中O元素的化合价由一1升高为0，由得失电
子守恒可知，KMO4与HO2的物质的量之比为2：3，氧化剂与还原剂的物质的量之比为2：3；在反应②中
没有元素的化合价发生变化，所以该反应不是氧化还原反应；反应③中产生1 mol KSbF。,生成0.25molF2,由
F元素的化合价可知转移电子为0.25mol×2×[0一（一1）]=0.5mol,数目为3.01×103；根据反应③可知每

A．在t℃时，AgBr的Ksp为4.9×10－13
B．在AgBr饱和溶液中加入NaBr固体，可使溶液由c点变到b点
C．图中a点对应的是AgBr的不饱和溶液
D．在t℃时，AgCl(s)＋Br－(aq)AgBr(s)＋Cl－(aq)平衡常数K≈816
2．不同温度(T1和T2)时，硫酸钡在水中的沉淀溶解平衡曲线如图所示，已知硫酸钡在水中溶解时吸收热量。下列说法正确的是(　　)
A．T1>T2
