大连市中考英语和化学答案
化学参考答案
33~47CABCDBDACCBDBAC
48.⑴支持呼吸⑵常温下碳的化学性质稳定⑶不可燃不助燃，密度大于空气
49.⑴水、氧气；涂油；Fe2O3+6HCl==2FeCl3+3H2O⑵Fe2O3+3CO高温2Fe+3CO2
节约有限的金属资源
50.⑴热能/内能/热量；充分⑵石油；酸雨；太阳能等
20.⑴乙⑵相等⑶降温⑷降温⑸37,5%
21.⑴4P+5O2点燃2P2O5；化合反应；⑵2H2O通电2H2↑+O2↑；分解反应；⑶H2SO4+Ca（OH）2====CaSO4+2H2O；复分解反应
22.⑴空气中含有多种分子/空气是由多种分子构成的⑵分子间有间隔，在水分子作用下糖的分子不断运动，彼此进入对方的间隔当中，使液体体积减小
22.⑴实验3中火柴在铁丝上方，用其火焰内焰对铁丝加热，内焰温度低，没有对铁丝充分预热，因此不能达到铁丝的着火点
⑵铁丝绕成螺旋状，与氧气接触面积增大，反应更充分
55.⑴2KClO32KCl+3O2↑；氧气不易溶于水⑵CaCO3+2HCl==CaCl2+H2O+CO2↑；带火星的木条方在瓶口，若熄灭证明已满；形成液封防止气体逸出
⑶H2CO3===H2O+CO2↑
第二节⑴铜；硫酸锌⑵向滤渣中加盐酸若有气泡，滤渣为铜和铁，则滤液为硫酸锌和硫酸亚铁；若滤渣中加盐酸无气泡，滤渣为铜，再向滤液中加铁片，有红色固体出现，滤液为硫酸锌和硫酸亚铁、硫酸铜；没有红色固体出现，滤液为硫酸锌和硫酸亚铁。
第三节 ⑴不需要，水的作用是判断反应是否进行完全（没有气泡说明反应完了）
⑵（二氧化碳没有被吸收，溶于水成酸性）D装置中可能看不到变红现象， 不能判断有氨气生成
⑶关闭K2,打开K1,充分加热，D中酚酞变红，说明有氨气生成，则有碳酸氢铵存在。
化学反应中元素种类不改变。
然后关闭K1,打开K2,当B中水里没有气泡时，试管中有剩余固体存在，说明有碳酸氢钠存在，因为碳酸氢铵分解后无固体；
58.⑴31.6g⑵47.4g×（64/158）-3.2g=16g，16g/（47.4g-3.2g）×100%=36.2%
