What is ionisation energy?

The easiest way to understand ionisation energy is to look at the equation for ionisation.For example, the ionisation of magnesium is shown by the following:Mg---> Mg + + e - The ionisation energy is then...

What is the ionisation energy trend as we go down the group and across the period?

Ionisation energy decreases down the group. This is because the atomic radii also inrease down the group, making the removal of an electron from the valence shell of an atom easier, as electrons located furt...

What is the limiting reagent and thus the mass of product for the reaction: P4O10 + 6H2O --> 4H3PO4 if 5.00 g of P4O10 react with 1.50 g of water?

1) Determine the moles of each reactant and thus the limiting reagent: # moles= mass (g)/M r . M r of P 4 O 10 = (4 x 30.97) + (10 x 16.00) = 283.88 g mol -1 . Moles of P 4 O 10 = 5.00/283.88 = 1.76 x 10 -2 ...
