I need a lab activity like the MgO -- burning magnesium in air. If you
measure the mass of Mg before and the mass of the product, you can find the
mole ratio. Does anyone know of another easily accelssible metal that burns
readily in air? I thought iron did, but I can't seem to make steel wool burn
in my lab.

Another idea would be a nice decomposition reaction like the hydrate lab. Is
there a compound that breaks down into 1 gas and 1 solid of which students
could find the mole ratio?

thanks,
sally
