Molar Mass of the NO = 14 g/mol + 16 g/mol = 30 g/mol
Number of mols is 2.79 g = 2.79mol/30g/mol = 0.093 mol
Heat released by the decomposition of 0.093 mol = 92.29kj/mol * 0.093 mol = 8.58 kj (you might include a negative sign to indicate tha the heat is released)

Answer:
A substance containing only one type of atom is a chemical element.
Answer:
Volcanoes form when magma from earth's upper mantle moves its way up to the surface. When the magma is all the way up the surface, it erupts and makes lava while at the same time, ash deposits. Once the volcano continues to erupt even more it starts getting bigger and bigger.

Answer:
![Fe(OH)_3(s)\rightarrow Fe^{3+}(aq)+3OH^-(aq)](https://tex.z-dn.net/?f=Fe%28OH%29_3%28s%29%5Crightarrow%20Fe%5E%7B3%2B%7D%28aq%29%2B3OH%5E-%28aq%29)
Explanation:
Hello.
In this case, for the reaction between aqueous solutions of ammonium chloride and iron (III) hydroxide, we have the following complete molecular reaction:
![3NH_4Cl(aq)+Fe(OH)_3(s)\rightarrow 3NH_4OH+FeCl_3](https://tex.z-dn.net/?f=3NH_4Cl%28aq%29%2BFe%28OH%29_3%28s%29%5Crightarrow%203NH_4OH%2BFeCl_3)
And the full ionic equation, taking into account that the iron (III) hydroxide cannot be dissolved as it is insoluble in water:
![3NH_4^+(aq)+3Cl^-(aq)+Fe(OH)_3(s)\rightarrow 3NH_4^+(aq)+3OH^-(aq)+Fe^{3+}(aq)+3Cl^-(aq)](https://tex.z-dn.net/?f=3NH_4%5E%2B%28aq%29%2B3Cl%5E-%28aq%29%2BFe%28OH%29_3%28s%29%5Crightarrow%203NH_4%5E%2B%28aq%29%2B3OH%5E-%28aq%29%2BFe%5E%7B3%2B%7D%28aq%29%2B3Cl%5E-%28aq%29)
Finally, the net ionic equation, considering that spectator ions are NH₄⁺, Cl⁻ as they are both the left and right side, therefore, the net ionic equation is:
![Fe(OH)_3(s)\rightarrow Fe^{3+}(aq)+3OH^-(aq)](https://tex.z-dn.net/?f=Fe%28OH%29_3%28s%29%5Crightarrow%20Fe%5E%7B3%2B%7D%28aq%29%2B3OH%5E-%28aq%29)
Best regards.
