答:若要消耗22t二氧化碳,理论上能得到甲醇的质量是16t。
【分析】(1)根据单质的概念是由一种元素组成的纯净物,化合物是由多种元素组成的纯净物,物质由元素组成来解答;
(2)根据图示分析可知当CuO的质量分数为50%,CH3OH的产率最高来解答;
(3)根据大量的二氧化碳会产生温室响应,二氧化碳可以转换成甲醇来解答;
(4)根据氢气和二氧化碳反应生成甲醇和水的方程式中的已知二氧化碳的质量和式量来计算甲醇的质量来解答。
(1)单质是由一种元素组成的纯净物,化合物是由两种或两种以上元素组成的纯净物。根据图1,甲醇化学式为CH3OH,由C、H、O这三种元素组成,属于化合物;
(2)由图2可知当CuO的质量分数为50%,CH3OH的产率最高;


反应方程式:________________________________。
氢气
一氧化碳
吸热
如:高锰酸钾分解,碳和二氧化碳的反应等。
2CO
