化学基礎の鉄の製造について質問です。 171の(2)を説明してほしいです。二枚目は答えとなります。

ので、 pH は小さくなる。陰極 (電極」 に影響しない。 補足 陽極(電極A)の反応 2CI- → Cla 2CI + 2H,0 → Clh+20H + Hz 両辺に変化しなかった2Na* を加えて整理すると, 2NACI + 2H,0 → Clz + 2NaOH + He 補足 この反応は NaOH と Cl, の工業的製法として重要である。 影響しない。 (b) 鉄鉄 (c) 鋼 【定数】アボガドロ定数 Na=6.0×10"/mol, ファラデー定数 F=9.65×10°C/mol リード C き, CO (2) 1.4kg C してCO。が生じ、 が生じる。 CO。 + 第7章 電池と電気分解 105 171. 鉄の製造品 次の文の[ ]に適当な語句を入れ, 後の問いに答えよ。 ト*170 CO。 鉄は、溶鉱炉(高炉)中でコークス(炭素) を用いて鉄鉱石を[ 丘を次のように目 して得る。このときに得られる 鉄は とよばれ,炭素を4%程度含んでいて, 硬くてもろい。 [ b ] を転炉に入れて酸素を吹 CO → 2Fe: き込み,炭素を2%以下にした鉄を[ こという。 鉄鉱石には,主成分が Fe.O3 の赤鉄鉱とよばれるものと, 主成分がFE.0. の磁鉄鉱とよばれるものがある。 (1) 溶鉱炉中では,コークスが反応して生じた気体が鉄鉱石を[ a ]している。この気体の物質名と化学式 A CO → 3Fe B → Fe + C02 ③式×6)÷3 よ D → 2Fe+ を乾留して得られ Pt Pt を答えよ。 物質名 目(I) 言液 ] 化学式 (2) 鉄の含有率96%の[ b ] を1.0kg得るには, 理論上何kgの酸化鉄(IⅢ) Fe:03 が必要か。 硝酸銀水溶液 kg の鉄鉄1.0kg X1s=1A·s=1C より, =0.96kg と。 0.96 kgを得る とx [kg]とする 12 -10.96kg 60 D0×10~°mol であるか mol のe-が流れた までの反応 e-2mol の移動で Cu feの合 *172.編の電解精錬 粗銅から純銅を得るための電解精錬について、 ( ) に当てはまる語句の組合せと して最も適当なものを, ①~⑥のうちから1つ選べ。 硫酸酸性の硫酸銅(IⅡ)水溶液中で相銅を陽極として電気分解することにより, 粗鋼中の銅は銅(1Ⅱ) イオン よりイオン化 t純銅が析出する。 銅よりもイオン化傾向が(ア )金属はイオンとなって溶液中
