<p>List all useful chemistry formulas that you have seen or are important to know. </p>
<p>Molarity= moles/ L</p>
<p>molality= moles/ kg</p>
<p>Boyles Law= PV=k
Ideal Gas= PV= nRT
Gay Lussac and Charles Law..</p>
<p>any more?</p>
<p>P1 V1 = P2 V2
V1/T1 = V2/T2
V1/n1 = V2/n2</p>
<p>STP 22.4 L/mol</p>
<p>Van der waals equation maybe?</p>
<p>As you can tell we just covered a chapter on gas laws. There are more formulas, but those came to mind immediately.</p>
<p>q=m delta T (specific heat)
couloumb’s law??</p>
<p>titration law i guess? idk if that’s the name but </p>
<p>MV=MV</p>
<p>gibbs’ free energy equation?</p>
<p>free energy = (delta)H - T(in kelvin) x (delta)entropy</p>
<p>dunno if it’s used… but why not</p>
<p>erm temp conversion F = 9C/5 +32</p>
<p>law of mass action R = k [A]^a **^b</p>
<pre><code> (equation : aA + bB -----> …)
</code></pre>
<p>K(sp) = concentration products of ions</p>
<p>pH = -lg [H+]</p>
<p>pH = 14 - ( -lg[OH-])</p>
<p>ALLOYS
brass = copper + zinc</p>
<p>bronze = copper, zinc and other metals</p>
<p>sterling silver = sliver + copper</p>
<p>steel = iron + carbon</p>
<p>Pewter = antimony, tin , copper and bismoth</p>
<p>Acids</p>
<p>Muriatic: HCl
Acetic: CH3COOH
Hypochlorus : HClO
Oxalic: H2C2O4</p>
<p>erm… dunno if this’s all even in course
i have an old version of the book
am i screwed or am i screwed??</p>
<p>…oh, and can somebody please tell me if we need to know how to correct readings in barrometers… and if so,HOW?!</p>
<p>gibb’s free energy is definitely used…</p>
<p>I thought SP was solubility product…</p>
<p>And law of mass action is actually in the test?</p>
