To make y the subject of the formula you have to rearrange it so that it starts with 'y=' instead of 'x='. Starting with x = (6+2y)/(3-y), if we get rid of the fraction by multiplying both sides by (3-y),...

N₂ (g)+3H₂ (g) ⇋ 2NH₃ (g)  ΔH=-92kJmol^-1 (this is the equation for the above question)
According to Le Chatelier's principle, the position of equilibrium w...

The main function of the future perfect is in future open conditionals. By a conditional, I mean a clause that includes “if” (Latin si); a future conditional is simply o...
