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!

碳被还原，从正 4 变为 0，从负 2 变为 0， 这意味着被。 这有可能发生！

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，首先是零价的元素被成（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这些东西时，电负性会告诉你很多信息。
