Answer:
Explanation:
2Al(s) + 3 I₂(s) → 2 Al⁺³ + 6 I⁻
Aluminium is oxidised and iodine is reduced .
so cell potential = Ereduction - Eoxidation
Al⁺³ + 3e = Al - 1.66 V
I₂ + 2 e = 2 I⁻ 0.54 V
= .54 - ( - 1.66 )
= 1.66 + .54
= 2.2 V
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances.
Answer:
in terms of chemistry, the forward reaction balances the backward reaction :)
Explanation:
Answer:
t ≈ 235.47 secs
Explanation:
<u>Calculate how long it will take the transformation to go to 88% completion</u>
Given that Avrami equation ( <em>y </em>)= 1 - exp( - kt^n )
n = 2.3
t = 145 secs
reaction = 50% after t = 145 secs
Reaction = 88% after t = ?
attached below is a detailed solution
Answer:
1. It contains protons,neutrons and electrons which is a true statement for atomic nucleus.
We can also determine number of valence electrons through atomic number by its electronic configuration. (K,L,M.... Shells)
