Why does propanol have a higher boiling point than propanone, propanal or methyl ethanoate?

Molecules of propanol have a hydrogen directly bonded to a NOF atom (oxygen in this case), which means that they can hydrogen bond with eachother. The oxygen in the other three molecules is only bonded to...

If we burn 3 moles of carbon in air (as per the equation), what mass (in grams) of carbon dioxide will be produced? What volume will this gas occupy at standard temperature and pressure?

So firstly, we assume that the oxygen is in excess (i.e. the amount of oxygen reacting won't limit the amount of carbon that can react), so we know that exactly 3 moles of carbon will be burnt. Then, from...

Why does the atomic radius decrease as you move along a period.

As you move along the period the proton number increases and the electrons are added to the same shell meaning no extra electron shielding occurs. Therefore the nuclear attraction to the outer most elect...
