填充題:
植物進行光合作用吸入二氧化碳放出氧 .
植物進行光合作用吸入二氧化碳放出氧氣.

兩個答案邊個係正確?

應該是 : 植物進行光合作用吸入二氧化碳放出氧氣.
因為我見阿仔WS 寫 "氧" 老師改卷時 氧氣.

Agree,

The second one is more specific. In fact both are correct.

May be next time, put it in the second method be more specific.

我女做功課寫氧氣, 老師改成氧.

難道真係要跟教科書來抄所謂的標準答案才為之正確嗎 ?

Not really ... according to chemistry books, both  answers are correct.

氧氣 = oxygen
氧 = oxygen

Anyway, this is just a translation issue. In fact, if the kid can answer the " 氧 " or "氧氣",  it is correct.

If the teacher insists to follow the model answer due to whatever reason, just let it be. It is nothing wrong.

csonliuson2000

100% agree.

如果考試時因呢類問題扣分, 就真係唔知應該係邊個的錯了.

龍: 唔好比太大壓力自己同亞女, 下學期再加油

我女功課都要求~~寫氧而不是氧氣.

有條題目答案係:
氧氣--濃度過高會爆炸.


個人覺得有些不妥, 因氧是不會自燃的氣體, 已寫紙問老師. 有冇家長可以証實下?

only high O2 will not, but with H2 it will.
