Nitrogen and hydrogen combine at high temperature, in the presence of a catalyst, to produce ammonia.
N2(g) + 3H2(g) ---> 2NH3(g)
Assume 4 molecules of nitrogen and 9 molecules of hydrogen are present.
1)After complete reaction, how many molecules of ammonia are produced?
2)How many molecules of H2 remain?
3)How many molecules of N2 remain?
4)What is the limiting reactant?

Glucose, C6H12O6, is used as an energy source by the human body. The overall reaction in the body is described by the equation
C6H12O6(aq) +6O2(g) ---> 6CO2(g) + 6H2O(l)
Calculate the number of grams of oxygen required to convert 43.0 g of glucose to CO2 and H2O.
Also compute the number of grams of CO2 produced.

Hello
we Can use different membrane process for the desalination of seawater, for example reverse osmosis, electrodialysis, nanofiltration ... but different method must be used according to the concentration of salt in the water, how to choose the ideal process to desalinate water from the Red Sea, the Dead Sea ?
Thank you
