“低碳循环”引起各国的高度重视，而如何降低大气中CO₂的含量及有效地开发利用CO₂，引起了全世界的普遍重视。所以“低碳经济”正成为科学家研究的主要课题

（1）用电弧法合成的储氢纳米碳管常伴有大量的碳纳米颗粒（杂质），这种颗粒可用如下氧化法提纯，请完成该反应的化学方程式： ___ C+ ___ KMnO₄+ ____ H₂SO₄→____CO₂↑+ ____MnSO₄ + ____K₂SO₄+ ____H₂O  

（2）将不同量的CO（g）和H₂O（g）分别通入到体积为2L的恒容密闭容器中。进行反应

CO（g）＋H₂O（g）CO₂（g）＋H₂（g），得到如下三组数据

①实验1条件下平衡常数K=________（取小数二位，下同）。

②实验3中，若平衡时，CO的转化率大于水蒸气，则a/b 的值_______(填具体值或取值范围)。

③实验4，若900℃时，在此容器中加入10molCO，5molH₂O，2molCO₂，5molH₂，则此时

V_正_____V_逆（填“>”、“<”“=”）。

（3）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

写出甲醇不完全燃烧生成一氧化碳和液态水的热化学方程式：______________________

（4）为最近有科学家提出构想：把空气吹入碳酸钾溶液，然后再把CO₂从溶液中提取出来，经化学反应后使之变为可再生燃料甲醇。该构想技术流程如下

向分解池中通入高温水蒸气的作用是_______________________________

（5）CO₂在自然界循环时可与CaCO₃反应，CaCO₃是一种难溶物质，其Ksp=2.8×10^-9。

CaCl₂溶液与Na₂CO₃溶液混合可形成CaCO₃沉淀，现将等体积的CaCl₂溶液与Na₂CO₃溶液混合，若Na₂CO₃溶液的浓度为2×10^-4mo1/L ，则生成沉淀所需CaCl₂溶液的最小浓度为

__________。

Alex Wood began fundraising when he was four years old. He sold lemonade and cookies to raise money for a school in Haiti. Later, Alex sent 15 bags of food he collected from his neighbors to a food store near his home which asked for donations(捐赠).

Alex wanted to help more people. He decided to donate to Heifer International, an organization that gives farm animals and farm training to poor people around the world. His goal: $5,000 for a “gift ark”. That amount would mean that 15 pairs of animals would be given to people in need. Those families would agree to give one of their animals’ young to other needy families.

Alex decided that baking was the best way to raise money. He started a business, named it Clean Hands Bakery, and now sells his baked goods year round. In his family’s kitchen, he created all kinds of cookies and cakes. He says his top sellers are lemon pound cakes and chocolate cupcakes. Alex likes the baking as much as the fundraising. “I like it that you can take so many ingredients(原料) that don’t taste good on their own and come up with something amazing,” he says.

In September 2011, Alex reached his goal of $5,000 and bought a gift ark. “I feel absolutely overjoyed that I got to my goal,” he says. “I can’t help everybody by myself, but I can do my part, which I hope will inspire other people to do their part, too.” One of the people Alex has already inspired is his younger brother. “He had people donate to me, instead of giving him a birthday present.” Alex explains. “In the end he donated $200 toward my goal.”

So now that he’s met his goal of a gift ark, will Alex keep baking and fundraising? He says yes. He wants to end world hunger, one cupcake at a time.
