Mercy me, how are cell potential, equilibrium constants, and free energy change all related? By a few different equations, that's how. See if you can solve for these values given some data!

We know that a lot of thermodynamic data is collected under standard conditions, but sometimes we will want to assess the free energy change associated with a process that is not occurring under standard conditions. Any other conditions...

Stoichiometry for combustion? You bet! If we know about moles, we can calculate energy changes. Give it a try!

The concept of the mole is a little tricky when you first learn about, but soon you're converting between grams and moles and atoms with ease. Let's practice some conversions using Avogadro's Number now!

We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

Did you know that (at least) one mark in the HSC Chemistry exam comes from using the correct units? If you know your SI units well, then you’re guaranteed a free mark! If only the rest of the exam was that easy! This lesson will cover...

If we can use the ideal gas law to find the molar mass of a gas and therefore identify the gas, what can we do with the density of a gas? Well, pretty much the same thing, it just involves one extra calculation, so let's give it a try!

y=mx+b for the Arrhenius Equation (Ln|k| vs [1/T])

We know about the ideal gas law, but what are some clever things we can do with it? Well, how about identifying an unknown gas by solving for its molar mass? Sure, why not!

What the heck is gravimetric analysis? Well let's say we want to know how much of a substance is in some mixture. We could toss it in solution and cause it to form a precipitate with some other ion in solution. We can measure the mass of...

How do we know how many atoms of each element are in a particular compound? Through clever experiments! Here let's practice using percent mass information to get the empirical and molecular formulas of a particular compound.

One of the most commonly performed techniques in the general chemistry laboratory is the acid-base titration. This is an analytical technique that we can use to determine the concentration of some analyte by titrating with some titrant...
