Answer:
0; +1; -1
Explanation:
The resonance structure of HN₃ is shown below (you can also use horizontal dashes to represent the bonding pairs).
The molecule has 16 valence electrons, and each N atom has an octet.
To get the formal charges, cut the covalent bonds in half.
Each atom gets the electrons on its side of the cut.
Formal charge = valence electrons in isolated atom - electrons on bonded atom
FC = VE - BE
(a) On Nₐ
VE = 5
BE = 1 lone pair (2)+ 3 bonding electrons = 2 + 3 = 5
FC = 5 - 5 = 0.
(b) On Nb:
VE = 5
BE = 4 bonding electrons = 4
FC = 5 - 4 = +1
(c) On Nc:
VE = 6
BE = 2 lone pairs(4) + 2 bonding electrons = 4 + 2 = 6
FC = 5 - 6 = -1
I don’t get it what do u need exactly?

Answer:
See explanation
Explanation:
In considering the sustainability of the two processes, we must remember that fermentation involves the use of sugars as raw materials. These sugars are grown naturally as plants from which sugars are extracted for the fermentation process. This is a sustainable process because sugar is a renewable resource.
On the other hand, ethene is produced from the cracking of fractions obtained from distillation of natural gas and oil. Natural gas and oil are not renewable resources hence the process is not sustainable. The cracking of ethene requires a lot of energy compared to the fermentation of sugar.
As regards atom economy, the cracking of ethene, C2H4(g) + H2O(g) ------> C2H5OH(g) has a better atom economy compared to the fermentation of sugar; C6H12O6(aq) -------> 2C2H5OH(aq) + 2CO2(g).
Atom economy has to do with the process of designing reactions in such a way that atoms which are in the starting materials end up in the final product and not as waste materials.
Fermentation produces a waste material which is CO2 while the cracking of ethene produces no waste material. All atoms of the reactants are converted into atoms of products.
Hence, the cracking of ethene displays 100% atom economy. This implies that all reactant atoms are found in the desired product.
