题目:

阅读下文:在通常情况下,硫化氢是一种没有颜色,具有臭鸡蛋气味的有毒气体,比空气重,能溶于水,在空气中点燃硫化氢气体有二氧化硫和水生成,硫化氢的实验室制法:用块状硫化亚铁和稀硫酸反应,就有硫化氢气体逸出,回答:

(1)具有臭鸡蛋气味,这属于硫化氢的______(物理、化学)性质.

(2)制取硫化氢气体的装置可选用______的气体发生装置,收集时可用______法.

答案:

(1)具有臭鸡蛋气味,描述的是气味,不需要通过化学变化就能表现出来,属于物理性质.

(2)制取硫化氢是用的固态硫化亚铁和液态稀硫酸,而且反应不需要加热,属于固液常温型制取气体,故气体发生装置可以选择制二氧化碳的装置;硫化氢密度比空气大,且能溶于水,可以用向上排空气法来收集;

故答案为:(1)物理;(2)二氧化碳;向上排空气.

请为下面这则新闻拟一个标题,字数12字以内。(3分)

央广网北京4月8日消息 据中国之声《全球华语广播网》报道,一段真实的、记录日本捕鲸船血腥捕鲸过程的视频显示,一艘巨大捕鲸船正在对一头鲸鱼围追堵截,在各种现代化捕鲸器械的攻击下,鲸鱼痛苦的翻腾着,蓝绿色的海水瞬间就变成了猩红色,随后,捕鲸者把奄奄一息的鲸鱼拉上船进行残忍的分割,甲板上血流成河。据了解,这样的画面在南半球的海域经常可以看到。

为了制止类似残忍血腥的事件今后再频频发生,海牙国际法庭日前就日本违反《国际捕鲸管制公约》进行判决,判定日本目前的捕鲸活动违反公约,令其今后不得继续这类的活动。不过日本虽然败诉了,但是日本方面表示,将在南极以外的海域继续开展所谓的"科研捕鲸"活动,"护鲸大战"的形势依然非常严峻。
