The balanced equation is:
![2Na_3N-\ \textgreater \ 6Na + N_2](https://tex.z-dn.net/?f=2Na_3N-%5C%20%5Ctextgreater%20%5C%206Na%20%2B%20N_2)
Then proceed with the following equations.
![100g Na_3N*(\frac{1molNa_3N}{82.98gNa_3N})*(\frac {6mol Na}{2molNa_3N})*(\frac {22.99gNa}{1molNa})=83.12gNa](https://tex.z-dn.net/?f=100g%20Na_3N%2A%28%5Cfrac%7B1molNa_3N%7D%7B82.98gNa_3N%7D%29%2A%28%5Cfrac%20%7B6mol%20Na%7D%7B2molNa_3N%7D%29%2A%28%5Cfrac%20%7B22.99gNa%7D%7B1molNa%7D%29%3D83.12gNa)
The answer is
![83.12gNa](https://tex.z-dn.net/?f=83.12gNa)
.
The primary structure is the amino acids' unique sequence. The polypeptide's local folding to form structures such as the α-helix and β-pleated sheet constitutes the secondary structure. The overall three-dimensional structure is the tertiary structure
Hey there!
HC2H3O2(aq) + H2O(l) → H3O⁺(aq) + C2H3O2⁻(aq)
↓ ↓ ↓ ↓
acid base acid base
If we consider the only forward reaction H3O⁺is the conjugate acid of the base H2O
. For reversse reaction CH3COOH is the conjugate acid of the base CH3COO⁻.
Hope this helps!
Ice melting is a physical change because you are not getting rid of anything, it is simply transforming into another state. The ice is melting because it is heating up and causing the molecules to speed up ans spread out, meaning all of the ice`s properties are still there, just in a different form.
Answer:
A. Physical Change
