ロ文型/文の種類 社会 1 25 rh Chapter Time: 35 mnutes 1 英文を読んで、設間に答えなさい。 Most important easons for doing voluntecr work Number of hous students volunteered per month 1%of students help people or community 44% 104 eam something new 24% Sto 10 get work eperience 20% 11 or more other 12% St. Martin's High School conducts a survey of student volunteer work 。 every year. The survey results show that many students have positive atitudes toward volunteering. The graph above shows the average amount of time that students spent doing volunteer work per month in this year. The table s shows the most important reasons given for participating. The teachers at the school have encouraged their students to volunteer since 2009. Before then, few students did volunteer work. When Brian Amster, the present principal, first came to the school in 2008, he found that there was litle communication among students, their families, and the 10 Community. As St. Martin's High School was in a newly developed arca, more than half of the students and their families were newcomers, and they did not know cach other or the area very well. Mr. Amster thought this was not good for the students and the communiry. Mr. Amster came up with the idea of volunteer work. p He wanted his の 15 students to have more contact with the local people through helping those in need. The local people really welcomed the volunteer activities. Volunteering gave many students a chance to learn a lot, and their self-esteem improved. It was good for the community and the students themselves, too. Mr. Amster says, "In the beginning, most of the volunteer activities 4 20 involved helping old people. Today, however, more and more students are doing activities related to the environment, such as cleaning parks and other public areas. Parents are also encouraged to help, and cach year, more and more parents are participating." One thing that makes Mr. Amster especially proud is that most students continue voluntering even after graduation. さ

投げやりとなってしまって申し訳ありません! どうやって解こうか浮かばなかったので途中式含め教えて欲しいです。

I IUI) 【1】リン酸は三塩基酸であり、理論的には三段階の解離が可能だが、 解離するほどその酸性度は低くなり、 第三解離を水溶液中で観察することは難しい。リン酸の第一~第三解離式及びそれぞれの酸解離定数 Ka」~Kas の式と値を以下に示す。 * 第一解離式: H3PO』 H* + HPO; Ka」= [H*][H2PO ]/ [H3PO.] = 10212 mol/L H* + HPO,?. ; Kaz= [H*][HPO,?] / [H2PO,]= 10721 mol/L 第二解離式:H2PO。 第三解離式:HPO, 上記の各解離式と各解離定数の式を参照し、 各種リン酸塩水溶液に関する以下の問いに答えなさい。 ただし、常用対数を計算に用いる場合には、log102 = 0.30, log103 =D 0.48 とする。 H* + PO ; Kas= [H*][PO]/ [HPO。] 3 1012.67 mol/L (1) NaH2PO4と NazHPO4 がそれぞれ 0.100 mol/L の濃度で溶けているリン酸緩衝液があるとき、 この pH を適切な有効桁数で求めなさい。 (2) (1)のリン酸緩衝液 100 mL を三角フラスコに取り、ここに 0.100 mol/L 塩酸を 25.0 mL 加えた とき、この緩衝液の pH はいくらか。適切な有効桁数で求めなさい。 (3) (2)の操作を行った緩衝液にさらに 0.100 mol/L 塩酸を加えていき、NaHzPO,水溶液としたとき の pH を適切な有効桁数で答えなさい。 ヒント:[HsPO«]=[HPO] となる。 Kaiと Kazの積を考える。 (4) (1)のリン酸緩衝液 100mL を三角フラスコに取り、ここに 0.100 mol/L の NaOH 水溶液を xmL 加えてから緩衝液の pH を測定したところ、 この緩衝液の pH は 7.39 となった。この x の値を適 切な有効桁数で求めなさい。 (5) (4)の操作を行った緩衝液にさらに 0.100 mol/L の NaOH 水溶液を加え、NazHPO,水溶液とし たときの pH を適切な有効桁数で求めなさい。ヒント: [H.PO«]=[PO]となる。 Kaz と Kasの積を考える。
