なぜナトリウムイオンが多いとわかるのですか? 解説を読んで水酸化物イオンは中和してイオンの数が減るとわかったのですがNa+も中和しませんか?教えてください💦

4 溶液について,火の各問に替んよ。 下の表は 100gの水が入った 2 つのビーカーに,それぞれ塩化ナトリウムと物質 A を 溶かして飽和水溶液としたときの, 溶液の温度と溶けた物質の質量の関係を示したもの である。これに関して次の実験 1, 2 を行った。なお, 物質 Aは, 水によく溶ける物質で 問1 ある。 【実験1】 10℃の水 100gが入ったビーカーに,塩化ナトリウムを加えて飽和水溶液をつくった。 【実験 2】 40℃の水 100gが入ったビーカーに,物質 Aを 30g 入れて完全に溶かし, 水溶液をつ くった。その後,この水溶液を 10℃までゆっくりと冷却したところ, 結晶が出てきた。 表溶液の温度と 100gの水に溶ける物質の質量 温度[℃) 0 10 20 30 40 50 塩化ナトリウム [g] 35 35 36 36 36 37 物質A [g] 13 22 32 46 64 85 (1) 実験1における, 塩化ナトリウムの飽和水溶液の質量パーセント濃度は何%か。 小数 第1位を四捨五入して整数で答えよ。 387 TI27 21- 251 (2) 実験2のように一度溶かした物質を結晶として取り出す操作を何というか。 また, 物 質Aの水溶液から出てきた結晶の質量は何gか。 問2 10cm3の水酸化ナトリウム水溶液に10cm3の塩酸を加え混合液をつくった。 この混合 液に BTB 液を加えると青色になった。さらに, 同じ濃農度の塩酸を少しずつ加えていくと、 5cm3加えたところで混合液は緑色に変化した。 (1) 下線部で示す混合液中に, 最も多く含まれるイオンは何か。 イオンの名称を答えよ。

これの(②)に一語を文章から抜き出していれるんですけど、quickはだめですか? 答えはearlyでした。

When I first moved to Japan, my new life was like an adventure, and full of surprises. Ive forgotten a lot of small things, but I'll never forget the first party I gave. 1was teaching English at a university in Japan. I decided to have a party for some Japanese students at my apartment which was near the school. The party was at 7:00. I was rushing to get ready, cleaning the room, checking the food, and so on. And finally at about 6:45, I was about to take a quick shower and get dressed. Perfect timing, I thought. But just then, the doorbell rang. The students, in one big group, were already at my door! In America nobody comes early, and in fact, most people come a little late on purpose, usually alone or in pairs. We call Oit being “fashionably late." I had to ask them to wait outside for about 15 minutes. “The party starts at 7:00!" I said, This was a real life lesson for them and for me about cultural differences. They learned they should not come to my parties ( ② ) again, and I learned I should be ready a little (2 )just.in.case. So at 7:00, everyone came in, with my second surprise. ③They showered me with all kinds of presents! I was happy to get so many presents, of course, but I really didn' t want them to come together. I was very busy because I had to find vases for the flowers, bowls for the snacks, and try to say Thank you' for their gifts. People usually take something likea bottle of wine to an American-style party. But I felt. more. appreciated by my_guests in Japan. It was more like my birthday or Christmas than a simple homeparty. FinallyI sat on the sofa and talked with them. Everyone was having a good time. Though I have lived in Japan for more than ten years, I m still surprised at many things. Life is full of surprises.

どなたか添削お願いします🙏🏻💧 (1,2枚目は問題、3枚目が私のです)

2次の文章は,カナタに帰国したJudy が Maki に送ったEメールの内容である。 Dear Maki, Thank you for your help during my stay in Japan. Do you remember that you took me to the Dream Festival ? I enjoyed it very much. I enjoyed learning about Japanese culture at the festival. I played the shamisen for the first time at the event "Try new things!" The sound of the shamisen was very new to me. It was a wonderful experience. I learned that it is very important for me to try new things.The shamisen was one new thing. In Canada, I have started to practice the shamisen. Ipractice it every day. e piu The other day, I went to a concert withmy sister, Amy. It was exciting ! Japanese *musical instruments, such as the shakuhachi, shamisen, and wadaiko, were played together with western musical instruments, such as drums and guitars. I was very surprised. When they were played together, music became more beautiful and powerful ! At the end of the concert, I was very happy to have a chance to play the shamisen witha special band on the stage ! That was a lot of fun. I found a new thing I wanted to do. I'm very glad about that. Have you started doing any new things? Ifyou have, tell me about them. I'm looking forward to hearing from you. Yours, Judy [注) musical instrument 楽器 western 西洋の powerful 力強い sheのふセでけどれか。
