Relationship between [H3O+] and [OH-] is:
[H3O+] X [OH-] = 1.00 X10^-14
Rearranging gives:
[H3O+] = 1.0X10^-14 / [OH-]
Just plug in and calculate your [H3O+] values
Answer:
The balance equation is
→ 
Explanation:
first, we have to make sure that the atoms are balanced
→ 
→ 
then we proceed to balance charges of each half-reaction
→ 
→

Now we multiply the half-reactions to match the number of electrons in each one
(
→
)x2
(
→
)x3
and now we do the sum of the half-reactions
2
→ 2
→ 3

→ 
note: the only atom that needed to be balanced was I
Answer:
it's because aluminium is a ductile material
