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 f...

What is the name of the compound with the formula CH3CH2CH(OH)CH3, and what is the name of its functional group?

The compound's name is butan-2-ol: four carbons in the chain means the compound has the but- prefix; the alcohol group is on the second carbon, so the compound has the -2- suffix; and the functional group...

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)/Mr . Mr of P4O10 = (4 x 30.97) + (10 x 16.00) = 283.88 g mol
