Nitrogen and hydrogen combine to form ammonia.
zhenek [66]

The balanced chemical equation for the formation ammonia is

    N2(g) + 3H2(g)  ----> 2NH3(g)  .        

The balanced chemical equations explains that the same number of each element exist as reactants and products.  The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.

For the formation of ammonia, the chemical equation is

     N2(g) + H2(g)  ----> NH3(g)

Balancing the chemical reaction, we can write,

  N2(g) + 3H2(g)  ----> 2NH3(g)  .  

This equation shows two nitrogen entering the reaction together and two hydrogens entering the reaction together. Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogen and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3. This is the balanced chemical reaction.

J. A gas has a volume of 12 L at 200°C with 6.0 atm.
White raven [17]

Gay Lussac's Law

\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}

Convert:

200°C = 200 + 273 = 473 K

50°C = 50 + 273 = 323 K

Input the value:

\tt \dfrac{6}{473}=\dfrac{P_2}{323}\\\\P_2=4.097~atm
