能源短缺是人类社会面临的重大问题。甲醇是一种可再生能源,具有广泛的开发和应用前景。

(1)工业上一般采用下列两种反应合成甲醇:

反应I:  CO(g) + 2H2(g)   CH3OH(g)    ΔH1

反应II: CO2(g) + 3H2(g)   CH3OH(g)  +  H2O(g) ΔH2

① 上述反应符合“原子经济”原则的是     (填“I”或“Ⅱ”)。

② 下表所列数据是反应I在不同温度下的化学平衡常数(K)。

温度250℃300℃350℃
K2.0410.2700.012
由表中数据判断ΔH1      0 (填“>”、“=”或“<”)。     

(2)已知在常温常压下:

① 2CH3OH(l) + 3O2(g) = 2CO2(g) + 4H2O(g) 

ΔH = -1275.6 kJ/mol

② 2CO (g)+ O2(g)= 2CO2(g) ΔH =-566.0 kJ/mol

③ H2O(g)= H2O(l)  ΔH =-44.0 kJ/mol

请计算1 mol甲醇不完全燃烧生成1 mol CO和液态水放出的热量为         

(3)利用甲醇燃料电池设计如右图所示的装置:

则该装置中Cu极为       极;

写出b极的电极反应式

when Frida Kahlo's painting were on show in London, a poet described her paintings as " a ribbon(丝带) around a bomb". Such comments seem to suggest Kahlo had a big influence on the art world of her time. Sadly, she is actually a much bigger name today than she was during her time.

Born in 1907 in a village near Mexico City, Kahlo suffered from polio(小儿麻癖) at the age of seven. Her spine(脊柱) became bent as she grew older . Then, in 1925, her back was broken in several places in a school-bus accident. Throughout the rest of her life, the artist had many operations, but nothing was able to cure the terrible pain in her back. However, the accident had an unexpected side effect. While lying in her bed recovering, Kahlo taught herself to paint.

In 1929, she got married to Diego Rivera, another famous Mexico artist. Rivera's strong influence on Kahlo's style can be seen in her early works, but her later works from the 1940s, known today as her best works, show less influence from her husband.

Unfortunately, her works did not attract much attention in the 1930s and 1940s, even in her home country. Her first one-woman show in Mexico was not held until 1953. For more than a decade after her death in 1954, Kahlo's works remained largely unnoticed by the world, but in the 1970s her works began to gain international fame at last.
