the balanced equation for the formation of ammonia is as follows
N₂ + 3H₂ --> 2NH₃
stoichiometry of H₂ to NH₃ is 3:2
in gases number of moles of gas is directly proportional to volume of gases.
therefore molar ratio is equal to volume ratios.
this means volume ratio of H₂ to NH₃ is 3:2
volume of H₂ reacted - 54.1 L
if 3 L of H₂ forms - 2 L of NH₃
then 54.1 L of H₂ forms - 2/3 x 54.1 = 36.1 L of NH₃
volume of NH₃ formed is 36.1 L

Answer: False
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Example:
has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.
has molecular formula of
but
as the empirical formula.
For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>
