In 1774 Joseph Priestly conducted one of his most famous experiments which
lead to a method for the preparation of oxygen. The experiment involved heating
a sample of mercury II oxide with a large lens.
The equation for this reaction is shown below:
2HgO(s) = 2Hg(l) + O2(g)
a) What volume of O2(g) would be obtained if 1.08g of mercury
II oxide were completely decomposed? (Given that 1 mole of a gas occupies 24
dm3 under the experimental conditions)
Here is a worked example. Just follow the steps.
According to the laws of thermodynamics, if you heat a large enought object, it gets enough energy it implies. What whould happen if you add 80 joules of energy to 1kg of zinc metal.... i just dont get it
