CH3CSNH2 + H+ + 2H2O→CH3COOH + NH4+ + H2S(aq)
CuS, Bi2S3 + NO3-→ Cu2+, Bi3+ + S↓ + NO↑
2Bi(OH)3(s) + 3Sn(OH)3- + 3OH- → 2Bi↓ + 3Sn(OH)62-
SbS33- + H+ → Sb2S3(s)
Sb2S3(s) + H+ + Cl- → 2SbCl4-(aq)
SnCl62- + 3H2C2O4 →Sn(C2O4)32-
SbCl4- + H2S → Sb2S3
Sn2+ + 2HgCl2 →Hg2Cl2(s) + Sn4+ + 2Cl-
Bi3+ 2Bi3+ + 3S2- → Bi2S3(s)
Bi2S3(s) + NO3-→ Bi3+ + S(s) + NO(g)
Bi3+(aq) + OH- → Bi(OH)3(s)
2Bi(OH)3(s) + 3Sn(OH)3- + 3OH- → 2Bi(s) + 3Sn(OH)62-
Cu2+ Cu2+ + S2-→ CuS(s)
CuS (s) +NO3-→ Cu2+ + S(s) + NO
Cu2+ + 4NH3→ Cu(NH3)42+
可能有人沒抄到 也有可能有人天賦異秉自己就會
不管怎樣請享用
(謝謝全國幫忙打講義的化學老師,經過這一晚我終於知道您的辛勤 )
(謝謝成功高中黃財堂老師,原來很認真的老師)
101A1 03 Problem Set 7
11/4/2008 in class.
1. (10 points) A spherical shell has inner radius R1, outer radius R2, and mass M, distributed uniformly throughout
the shell. What is the magnitude of the gravitational force exerted on the shell by a point particle of mass m
located a distance d from the center, outside the inner radius and inside the outer radius?
2. (10 points) Each of the four corners of a square with edge a is occupied by a point mass m. There is a fth
mass, also m, at the center of the square. To remove the mass from the center to a point far away, what is the
work that must be done by an external agent?
3. (10 points) Without neglecting the revolution of the earth, calculate the escape velocity from the surface of the
earth at the latitude north 25 degree. (take the radius of the earth 6370 km and the mass of the earth 5:981024
kg)
4. (10 points) problem 99 in chapter 13
5. (10 points) problem 56 in chapter 13
6. (10 points) problem 21 in chapter 14
7. (10 points) A bucket contains the water of half of its full volume. Now, the bucket is rotating with the angular
velocity ! and the surface of the water forms a certain shape. Show that the shape satises the following relation
h(x) = !
3g x3, where h is measured from the lowest of the surface and x is measured from the rotational axis.
8. (10 points) problem 65 in chapter 14
9. (10 points) problem 72 in chapter 14
10. (10 points) problem 48 in chapter 14
由於處於金屬和非金屬中間，同時具有兩者的特性。 作為金屬，可氧化至二價錫和較穩
家的四價錫。二價錫是兩性的，在酸中，可形成 [SnX3]-離子，X為F-,Cl-等；在鹼中，
會形成[Sn(OH)3]-電漿。四價錫也是兩性的，在酸中，可形成 [SnX6]2-離子，X為F-,Cl-
等；在鹼中，會形成[Sn(OH)6]2-, [SnO3]2-電漿。四價錫的溶液都傾向水解出SnO2沉澱
。 作為非金屬，錫可和碳，氧等非金屬組成份子。尤其是碳，可和錫形成很多有機錫化
合物，應用很廣泛。
