下表所列各组物质中，物质之间按箭头方向通过一步反应不能实现如图所示转化的是

物质

选项

甲乙丙
A．Fe2O3CO2H2O
B．CCOCO2
C．CaCO3CaOCa(OH) 2
D．H2SO4H2OH2

答案

答案：C

题目分析：A 三氧化二铁和一氧化碳反应生成二氧化碳，二氧化碳通入澄清石灰水中生产碳酸钙和水，三氧化二铁和稀硫酸反应生成硫酸铁和水，所以能实现上述转化，B碳不完全燃烧产生一氧化碳，一氧化碳燃烧会产生二氧化碳，碳完全燃烧会产生二氧化碳，C碳酸钙高温分解生成氧化钙，氧化钙和水反应生成氢氧化钙，但碳酸钙不能一步得到氢氧化钙，D中硫酸和碱反应生成水，水通电分解得到氢气和氧气，硫酸直接和活泼的金属反应会生成氢气，所以也能实现上述转化，故选C
