化学基礎の化学反応式の書き方についてです。 ②は、H原子が8なのに係数がなぜ4になるのでしょうか？ 後、③の6＋4=10で、係数が５になるのもよくわからないので、お願いします。

①最も複雑な化学式 C3Hg の係数を1とおき,C原子の数を合わせる。 左辺のC原子の数は3なので,右辺のCO2の係数は3とする。 3 CO2 + H2O 1C3H8 + 02 → ②H原子の数を合わせる。 C ように反応す 5 左辺のH原子の数は8なので,右辺のH2Oの係数は4とする。 を表す化学 → 1CH + O2 - 3CO, + 4H,O 図 16 プロパニ か。 ③0原子の数を合わせる。 右辺の原子の数は6+4=10なので, 左辺のO2 の係数は5とする。 1C3H + 502 +502 → 3CO2 + 4H2O 10 ④係数の1を省略する。 C3H + 502 → 3CO2 + 4H2O 応式 chemical equation 例題 4 エタン C2H が完全燃焼する反応の化学反応式を決定しよう。 の)を辺 生成物(一酸化炭素CO 水HO)を右辺に書

そうしないと、すなわち Carbon is an element found in such chemical compounds as petroleum and hob methane. It can arrange its atoms into several different forms, or "allotropes." For example, if the carbon atoms form a cubic system, the allotropes of carbon become a diamond; meanwhile, if they are bonded together to form layers of hexagonal lattice, they become graphite Man

15 The secret of how to make a perfect cup of tea has finally been discovered by put the milk in first. The finding that a cup of tea tastes better English scientists if the tea is poured into the milk appeared to have settled an argument that has been of major concern to this nation of tea drinkers. 52 It all began after Dr. *Andrew Stapley, a chemical engineer at *Loughborough University, revealed 3) the recipe for a perfect cup of tea. He said the keys to producing the perfect cup were using *soft water, warming the pot and allowing the tea to stand for three minutes. As to the difficult issue of whether the milk or tea should be poured in first, Dr. Stapley said science proved it must be the former. The reason is that 10 when milk is exposed to high temperatures, such as being poured into a cup of very hot tea, it loses its fresh taste. 3 However, only a few hours after Dr. Stapley announced his findings to the world, a noisy debate started within the scientific community. Dr. Julia King, head of the *Institute of Physics, said the secret was to keep the water temperature at 98°C. Putting the milk in first was only a social custom that "has nothing to do with taste," she said. "In the past, only the rich could afford high quality *china cups which could withstand the hot tea being poured in directly. In contrast, those of us with cheap china had to put the milk in first to prevent our cups from cracking." ウ 262 words)
