Explanation:
The Chemical equation for the formation of rust is:
Iron + Water + Oxygen ----> Rust
4 Fe(s) + 6 H2O(l) + 3 O2(g) → 4 Fe(OH)3(s)
The Iron Hydroxide However dehydrates to produce Fe2O3 * nH2O

Answer:
trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.
Explanation:
Here,
H(hydrogenated pdt.) is same for both 1,4-pentadiene and 1,3-pentadiene as they both produce pentane after hydrogenation
H(diene) depends on stability of diene.
More stable a diene, lesser will be it's H(diene) value (more neagtive).
trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.
Hence, is higher (less negative) for trans-1,3-pentadiene
