Le Chatelier's principle simply explains how equilibria change as you change the conditions of a reaction. If you have a reaction that is at equilibrium lets say (A + 2B <--> C + D) by removing C or D we can drive the reaction forward and products more products. I can provide a more in-depth description if needed.
A. magnesium sulfate heptahydrate
that is what it stands for
(18000 L/hr) x (3 hr) x ( 0.965 kg/L) = 52110 kg
2Na + 2H₂O → 2NaOH + H₂
2 mol H₂O - 1 mol H₂
0.30 mol H₂O - x mol H₂
x=0.30*1/2= 0.15 mol
