For the reaction of ammonia formation, for instance: N2+3H2=2NH3, we have cN2cH23/cNH32=K(T)/p2. When the pressure increases, the right-hand side of this equation decreases, and the left-hand side must therefore decrease also. Thus the equilibrium concentrations of the initial substances...
To write a balanced chemical equation for the preparation of methane from sodium acetate, we need to follow these steps:Step 1: Identify the Reactants The reactants for the preparation of methane from sodium acetate are sodium
You have a balanced equation N2+3H2 = 2NH3 + heat Alright, let's take the ammonia out, decreasing the chemical concentration of the right N2+3H2 = heat Le Chatelier's principal states that the system will shift its equilibrium position to counteract the disturbance. Ammonia was removed so...

Considering this equation, the increment in conductivity of the reaction mixture during the reaction indicates the silver ions were progressively exchanged for more mobile H+ ions. This supports this proposed mechanism (Pastoriza-Santos and Liz-Marzán, 1999). Like other methods of synthesis of silver...
A 25.0 mL sample of sulfuric acid is completely neutralized by adding 32.8 mL of 0.116 mol/L ammonia solution. Ammonium sulfate, (NH4)2SO4, and water are formed. What is the concentration of the sulfuric acid? And here I am trying to balance the equation for an hour until I finally gav...
We have developed an evolution code for brown dwarfs that assumes an adiabatic internal structure. It uses the H/He equation of state of Saumon et al. (2005). Nu- clear energy generation through the first branch of the pp-chain (Burrows & Liebert 1993) is included. We use ...
Balanced Equationeaction Evidence 15. Before chemistry labs were properly ventilated(many,many years ago),many chemistry labs would accumulate a film of white dust on the lab counters. This was due to the fact that hydrogen chloride and ammonia gases would build up in the room and react in ...
