※ 引述《junnyia (絕路)》之銘言：
: 4. a chlorine-oxygen compound iis found to have a chlorine to oxygen mass
: ratio of 1.109.whitch of the following chlorine to oxygen mass ratio is
: possible for a different chlorine-oxygen compound??
: a)1.000
: b)1.214
: c)2.428
: d)4.437
: e)5.014
這個應該是問倍比定律吧
會是簡單整數比
so...
(D)是整數比
: 是個不懂題目再問什麼的情形....
: 17.when 10g samples of the following materials absorb 100J of heat,
: the temperarure increase undicated is observed. which material has the
: largest specific heat??
: a)water 2K
: b)wood 6K
: c)copper 26K
: d)cemebt 11K
: e)glass 12K
specific heat是指一克溫度升高一度的值
一樣熱量(A)只有升高2度所以(A)最大
: 21.怎樣的電子轉移可放出最長波長在波耳氫原子中
: 1.3到4
: 2.4到1
: 3.4到2.
: 4.1到5
: 5.4到3
放出波長最長
也就是放出能量最低
氫原子電子軌域n2→n1
能量公式為△E = 313.6[(1/n1)^2-(1/n2)^2]
: 還有23 28 43 37 39 晚一點我在打題目...
有錯誤還請大家指正
