(普高完成)W、X、Y、Z是原子序数依次增大的同一短同期元素,W、X是金属元素,Y、Z是非金属元素.

(1)W、X各自的最高价氧化物对应的水化物可以反应生盐和水,该反应的离子方程式为______.

(2)W与Y 可形成化合物W2Y,该化合物的化学式为______.

(3)Y的低价氧化物通入Z单质的水溶液中,发生反应的化学方程式为______.

答案

(1)W、X为金属,其最高价氧化物对应的水化物为碱,且两种碱可以反应生成盐和水,则为NaOH和Al(OH)3,二者反应的离子方程式:Al(OH)3+OH-=AlO2-+2H2O,

故答案为:Al(OH)3+OH-=AlO2-+2H2O;

(2)W为Na,W可以和Y形成W2Y,则Y为-2价,为ⅥA元素,且和钠同周期,所以为S,W2Y为Na2S,故答案为:Na2S;

(3)Y的低价氧化物为SO2;并且Z和Y同周期,原子序数比Y大,所以Y为Cl.Y的低价氧化物和Z的单质反应的方程式:SO2+Cl2+2H2O=H2SO4+2HCl,

故答案为:SO2+Cl2+2H2O=H2SO4+2HCl.

"When I look back on my childhood I wonder how I survived at all. It was, of course, a miserable childhood. The happy childhood is hardly worth your while. "Worse than the ordinary miserable childhood is the miserable Irish childhood. And worse yet is the miserable Irish Catholic childhood." That was Frank McCourt reading the opening lines of his book Angela's Ashes, released in 1996.

This Irish American author best known for the Pulitzer Prize-winning autobiography Angela's Ashes that recorded his poor upbringing, died of cancer on Sunday, The New York Times reported. He was 78.

Born in New York City, he was the eldest of the seven children born to Irish immigrant parents. Angela's Ashes was a memoir(回忆录)that captured an irresponsible, drunkard(酒鬼)father with a gift for story-telling. When not drunk, his father was absent, turning his back on a family so poor, McCourt wrote, that they were reduced to burning the furniture in their rented hut to keep warm. His mother struggled to raise her many children after his father left the family.

In Angela's Ashes, he wrote of hunger, a home flooded with rainwater and the unbearable humiliation(耻辱)of seeking handouts from charities in the Irish city. But he told the story in a way that is expressive, warm and light-hearted.

Frank McCourt left Ireland at the age of 19 to return to New York City where he was born. He earned a degree in English education and taught creative writing for nearly thirty years. After retiring in 1987, he decided to write about his childhood. "Angela's Ashes" became a huge success and brought McCourt a 1997 Pulitzer Prize, the National Book Critics Circle Award and other honors. Millions of copies of the book were sold worldwide and it was adapted into a 1999 movie starring Emily Watson and Robert Carlyle.
