Chemistry: About carbon reacting with oxygen-- 10 pts!!

1. In incomplete combution(不完全燃燒) (燃燒=burn=combustion=react with oxygen).
不完全燃燒 is a substance react with oxygen which is not enough. (和不足夠的氧做反應)
Normally, carbon will react with enough oxygen to form carbon dioxide as a only product.
C + O2 = CO2
However, if oxygen is not enough, some carbon may not react with oxygen and remains as carbon and some will also form carbon monoxide.
因為氧不足夠,碳和氧未必能夠以1:2 (CO2 is C:O= 1:2) 的方式結合
(e.g. 因為1個碳要和2個氧反應,但有時未必有2個氧,所以碳會和較少的氧反應形成一氧成碳CO)
什至有些碳因氧不足而沒有參與反應,所以也會有碳粒的形成.

2. Because the reaction of carbon with not enough oxygen MAY NOT produce enough carbon monoxide and the process of producing amount of carbon monoxide is not easy to control, as i said before, carbon will form also.

But if carbon react with carbon dioxide in factory, it is reacting with excess carbon dioxide, so amost all carbon will react.

In carbon react with oxygen, not all carbon can react to form CO
In carbon react with carbon dioxide, as there are so many CO2, amost all carbon can form CO
