Carbon is reduced, going from an oxidation number of plus 4 to 0, and oxygen goes from negative 2 to 0, meaning that oxygen is oxidized. It can happen!

被还原，氧化数从正 4 变为 0，氧从负 2 变为 0， 这意味着氧被氧化。 这有可能发！

When you break this down in to half reactions, first you have elemental zinc with an oxidation number of 0 being oxidized to zinc 2 ion.

当你将其分解为半反应时，首先是零价的锌元素被氧化成锌离子（Zn²⁺）。

And especially when you start going into oxidation numbers and things like that, electronegativity will tell you a lot.

特别是在你开始涉及氧化数这些东西时，电负性会告诉你很多信息。
