ample practices varied across time and place. The truth is that we about what preliterate societies knew or believed. But they left behind *. evidence of their attention to the movements of the Sun and the phases of the Moon. And we can be sure that whatever questions they asked of the heavens were very different from those that motivate space exploration today. (A) rotic othe In reality, the difference between ancient and modern knowledge systems is more qualitative than quantitative; it is not about how much is known, but about what questions are important and about the acceptable ways of asking and answering those questions. And while we may not easily be able to slip between our modern worldview and those of others, we can nonetheless attempt to do so by asking not what ancient people knew about the world, but what their questions were when they looked at it. If we do this in the case of Mars, examining a few of the earliest known examples from around the world, we can see how sky knowledge was considered important to the functioning of the state whether it was *astrological knowledge in the service of good governance, or knowledge of bloodlines and relationships with the gods and other sky entities, which was used (B) - verdd

最後のNaCL の濃度を求めるときの式が分かりません。

する酸素の体積は何 mL か。 解答を導く過程を示し, 有効数字2 けたで答えなさい。 次の文章を読み、 以下の問い(問1 6 )に答えなさい。ただし, 塩化銀およびクロム酸銀の浴解度積は 人>C においてそれぞれ1.8x10-"(mo* および3.0x10-『(moM1)! とする。また, 必要であれば 3=1.73 を用いなさい。 物質の量を定量的に分析する手法の一つに滴定法がある。滴定法には酸と塩基た用いたしア_請定, 過マ ンガン酸カリウムのようなしイ 剤とシュウ酸のようなしウー]剤を用いたしエー請定がある。また, 難深性 塩の沈典生成を利用して水溶液中のイオン濃度を求めることができる沈殿滴定もある。 沈殿滴定の一つであ るし 潜はクロム酸カリウムを用いた塩化物イオンの定量法である。 しキ 」法について, 以下の実験を行 った。 実験1 25C において塩化物イオンとクロム酸イオンをそれぞれ1.00X10~*mol/L 含む水溶液中に硝酸 銀水溶液を滴下したところ, はじめに白色沈殿が生じた。さらに@硝酸銀水溶液を滴下していくと, 暗赤 色沈殿が生じた。 実験2 ある濃度の塩化ナトリウム水溶液を 10.0mL とり,0.0100moL のクロム酸カリウム水溶渡を 11.0 mL 加えた。25C において 0.0100mol/L の硝酸銀水溶液で滴定したところ 12.0mL で暗赤色沈殿が生じた。 問1 てはまる適切な語句をかきなさい。 間2 下線部①および②④で起こる反応をイオン反応式でかきなさい。 間3 チキ 」法におけるクロム酸カリウムの働きについて 60 字以内で説明しなさい。ただし, 説明には「暗 赤色」と「未反応の塩化物イオン」の語句を必ず用いて答えなさい。 問4 実験1で最初の沈殿が生じるのに必要な最小限の銀イオン濃度は 25C において何 mol/L か。 計算過 程も示し, 有効数字2 けたで答えなさい。 問5 実験1で暗赤色沈殿が生じたとき, 白色沈殿に含まれる陰イオンについて, 滴定前の何%が沈殿した か。 計算過程も示し, 有効数字 2 けたで答えなさい。ただし, 滴下した硝酸銀水溶渡による体積変化は無 視できるものとする。 問6 実験2で塩化ナトリウム水溶流の濃度は何 mol/L か。 計算過程も示し, 有効数字 3けたで答えなさい。
