BIO都會教的

難怪我唔識

拎D魚做實驗,冇人性

魚都有生命架  人渣!

嘩 好叻呀 咁都比你稔到

咁得閒開新AC=]

哇
跟佢個方法
d金魚一定養到肥肥白白!

其實我生物和化學科便真是很廢而已,不過二氧化碳這東西便應該不少人知道
但是真的有人未學的吧(唯獨是看到天才兩字便有點...... )

可以咁講,水入面有大部分係CO2

証據?

照你咁講水入面有大量鈾235都可能

水入面點會大部份係二氧化碳 -_-  4505別屈我機吧 :o

証據?

Water (H₂O, HOH) is the most abundant molecule on Earth's surface, constituting about 70% of the planet's surface. In nature it exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a nearly colorless with a hint of blue, tasteless, and odorless liquid. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some of its properties may vary slightly from those of the pure substance. However, there are many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter—for other substances, see Chemical properties. Water is essential for life on Earth.Water usually makes up 55% to 78% of the human body.

地球有水既地方係=]
水以水迴圈為載體存在於地球上，包括大氣層，土壤含水，河流水，地下水，植物含水。

地球上的水含量（全部水）大約是1 360 000 000 km³ (326 000 000 mi³)。包括了：

1 320 000 000 km³ (316 900 000 mi³ 即 97.2%)在海洋中。
25 000 000 km³ (6 000 000 mi³ 即1.8%) 在冰川，冰蓋，冰原中。
13 000 000 km³ (3,000,000 mi³ 即0.9%) 是地下水。
250 000 km³ (60,000 mi³ 即0.02%)是淡水，包括河湖，內陸海。
13 000 km³ (3,100 mi³ 即0.001%)存在於大氣層中。
