C 18 nov an example of oxidation, A, D and E are examples of rapid oxidation, because in each case the oxidation goes on so rapidly as to produce light and noticeable heat,
d is an example of oxide tion which goes on ss 'alowly as to produce no light" and no noticeabl

You would Geen turn to the answer angez am at the corresponding number (in this case 1) fill the block B with a

A. Alcohol
B. Benzene
C. Carbon disulphide
D. Gasoline by
E. Turpentine
Among the above list of solvents, grease will dissolve only in benzene. The answer then 15 8,

3. The following charges are either chemical
changes or physical changes.

1 and I only
HI and waly
1 II and V only
II III and IV only
6, 121, and V only
Booking at the first fist, we can see that and V are chemical changes: anding water to "health salts produces a gas, carbon dioxide; milk turns sour owing to the formation of Lactic acid In II, Ill and IV no new substances are formed. They are all physical changes. Therefore alternative D is the Borrect answer.

150 gm of saturated solution at 80°°C contains 50 gm of salt and 100 gm.of water

remaining then contains 40 gm of salt dissolved in. 200 gu. of water-
Hence the solubility of the salt at room temperature
Questions for next week:

element other than oxygen."

(一)一般的二位數,可將二位數的頻位數字減去十位數字,若不够波則先加上11然提浓,
例:8的餘數是(8632
BI的I1餘数但是(1+119) 4
(二)關於二位以上的多位數,可將懷多位數從個從戰的起,每二個數看成一對,分成若干时
