问题 填空题

生活中的广告与化学联系密切,请欣赏以下两则广告:①黄金搭档,花一样钱补五样;②葡萄糖酸锌口服溶液,蓝瓶的,好喝的.填写下列空白:

(1)黄金搭档所补的五样是指:Ca(名称为______)、铁、锌、硒、维生素.其中前四样是指人体需要这四样______(填“单质”或“离子”或“元素”),这四样中有一样不同于其它三样的是______.

(2)葡萄糖酸锌口服溶液中所含的金属离子为______,溶液中所含的氧化物是______.(填化学符号)

答案

(1)根据元素与微观粒子及物质的区别.宏观物质的组成,用宏观概念元素来表示;分子的构成,用微观粒子来表示.元素是具有相同核电荷数(即核内质子数)的一类原子的总称,是宏观概念,只讲种类,不讲个数.食品、药品、营养品、矿泉水等物质中的“碘、氟、钙、铁、锌”等不能以单质、分子、原子形式存在,而是指元素;化学元素汉字名称的偏旁可辨别元素的种类,固态非金属元素名称有“石”字旁;前三种为金属元素,硒为非金属元素;

故答案为:钙;元素;硒;

(2)葡萄糖酸锌口服溶液中所含的金属离子为 Zn2+,氧化物是指由两种元素组成且其中一种是氧元素的化合物,溶液中所含的氧化物是H2O,

故答案为:Zn2+;H2O.
