A mole in chemistry is a unit of amount. Similar to saying a dozen is 12, a mole is 6.022x10^23 atoms, conveniently called Avogadro's number. If we take one mole of carbon atoms, this is equal to a mass o...

An increase temperature favours the endothermic direction of an equilibrium reaction; this is because there is more energy in the surroundings to accommodate for the energy that will be taken into the sys...

The limiting reagent is the chemical substance that isn't in excess in the reaction compared to the other components. The way to calculate which reagent limits the reaction and how it progresses is to cal...

HF has the highest boiling point this is followed by HI, then HBr with HCl having the lowest boiling point of the four molecules. This is because HF is able to form Hydrogen bonds whereas the other three ...
