Chapter 6 - What Are The Mechanisms Of Chemical Change?

<ul>
	<li>What is it? When substances burn in oxygen.</li>
	<li>Who gets in on the action? Metals, non-metals, and hydrocarbons.</li>
</ul>

<ul>
	<li>Result? The metal gets &quot;oxidized&quot; (think of it as the metal getting an oxygen mask), and oxygen gets &quot;reduced&quot; (it&rsquo;s like oxygen goes on a diet and loses some electrons).</li>
	<li>Bonus Term: This is called a Redox reaction. (Redox = Reduction + Oxidation)</li>
</ul>

🌎 Real-world analogy: Imagine oxygen as a hungry monster that wants electrons. Metals, being generous, give some of theirs away! Metals &quot;lose weight&quot; in electrons (oxidation) while oxygen gains (reduction).

<ul>
	<li>Oxidation: It&#39;s like a gain of oxygen or when someone (like a metal) loses their electron coins.</li>
	<li>Reduction: It&#39;s when someone loses oxygen or finds some electron coins.</li>
</ul>

🌎 Real-world analogy: Think of electrons as money. Oxidation is like spending money, and Reduction is like earning it.

Metal + Oxygen = Metal&#39;s New Outfit (Metal Oxide)

<ul>
	<li>
	Lithium (Li): When you light up Lithium, it gets hot, gives energy, and changes into lithium oxide.

	<ul>
		<li>Equation: 4Li(s) + O2(g) &rarr; 2Li2O(s)</li>
		<li>Electron Magic: Li &rarr; Li+ + e&minus;</li>
	</ul>
	</li>
	<li>
	Magnesium (Mg): Magnesium puts on a bright white show when it meets oxygen and then turns into magnesium oxide.

	<ul>
		<li>Equation: 2Mg(s) + O2(g) &rarr; 2MgO(s)</li>
		<li>Electron Magic: Mg &rarr; Mg2+ + 2e&minus;</li>
	</ul>
	</li>
</ul>

🌎 Real-world example: Think of Lithium and Magnesium as two friends at a party. Lithium gives a warm welcome while Magnesium enters with a bright flashlight, both leaving the party with a changed outfit!

<ul>
	<li>Oxygen grabs the electrons (remember, it&rsquo;s hungry for them!) and becomes O2&minus; ions.
	<ul>
		<li>The magic spell: O2 + 4e&minus; &rarr; 2O2&minus;</li>
	</ul>
	</li>
</ul>

🌎 Real-world analogy: Think of Oxygen as a shopper during a sale. It goes on a shopping spree, grabbing all the electron products it can find!

<ul>
	<li>Combustion = burning in oxygen.</li>
	<li>Metals lose electrons and get oxidized.</li>
	<li>Oxygen gains electrons and gets reduced.</li>
	<li>Redox = the party where this electron exchange happens.</li>
</ul>
