The internal energy : 1310.43 kJ/mol
<h3>Further explanation</h3>Internal energy (ΔE) can be formulated for Calorimeter :
C= the heat capacity of the calorimeter
Δt=36.2-25.68=10.52°C
- mol butane(MW=58,12 g/mol)
- the internal energy (ΔE) in KJ/mol

Answer: 0.050 moles of nitrogen monoxide are produced by 0.050 moles of ammonia.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction is:
According to stoichiometry:
4 moles of ammonia produce = 4 moles of nitrogen monoxide
Thus 0.050 moles of ammonia produce = moles of nitrogen monoxide
