six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine.
Just try to find how you will get the reaction by adding the other reactions. Reverse the second eq as O is in reactant side and half it..
Now in the final reaction there is neither ozone nor oxygen so now you have oxygen on the products side after adding reversed
2 and 3, O ->1/2 O2
adding this to the third eq you get,
NO+O +O3 -> NO2 +3/2 O2
Now you need to remove O3 and O2 using the first equation,
So reverse the first one,half it and add, 3/2O2-> O3 adding it removes O3 and O2 you get the requires equation,
NO + O->NO2 you can do the calculation bit yourself when you add reactions Enthalpy is also added by Hess law so yeah that part should be pretty simple.
0.534 g/cm^3 This is very low.

Explanation:
One must first balance the metals before balancing non-metals such as Oxygen and Hydrogen (Hydrogen isn't involved in this case).
So therefore on the right hand side you see 2 Aluminium atoms and thus one must add a 2 before the Aluminium on the left hand side.
Secondly the Iron must be balanced, on the left it can be seen that there are 2 Iron atoms in
F
e
2
O
3
and thus a 2 must be added on the right hand side in order for them to balance.
Lastly the Oxygens must be balanced but in this case they already are at 3 on each side and thus the whole equation is now balanced.
Hope I helped :)
