(3)越活泼的金属越难冶炼,人类对铁的利用比铜晚,这是因为铁的金属活动性比铜的金属活动性强;“熬胆矾铁釜,久之亦化为铜”是因为硫酸铜与铁反应生成铜和硫酸亚铁,化学方程式为CuSO4+FeFeSO4+Cu。
11.(1)FeSO4　Cu　
(2)②③
(3)Fe2O3+3CO2Fe+3CO2
(4)Fe+H2SO4FeSO4+H2↑
解析:A是赤铁矿的主要成分,所以A是氧化铁,氧化铁与一氧化碳反应生成二氧化碳和铁,所以C是铁,E是硫酸,铁与稀硫酸反应生成硫酸亚铁和氢气,G溶液为蓝色,所以G是铜的化合物,铁与铜的化合物发生置换反应生成铜和二价铁的化合物,所以D是硫酸亚铁,B是氢气,F是铜,经过验证,推导正确。
(1)由分析可知,D是FeSO4,F是Cu。


（2）①④⑤⑥⑦⑩ BD
（3）便于（可以）控制反应的速率 n （4）3
19．（8分，化学方程式2分，其他每空1分）（1）硬，Cu、Mn，
（2），澄清石灰水变浑浊，在导管口末端放一盏燃着的酒精灯或套一个气囊，铜，e
五、综合计算题（共10分）
20．（共10分）（1）C（1分） （2）硬度更大或抗腐蚀性能更好等（合理即可）（1分）
（3）①加快反应速率，使反应充分进行（1分）②Mg2+（1分）
