Answer:
The voltage is 
Explanation:
Generally the half reaction for Zn, Zn2 half-cell is mathematically represented as
⇔
(reference study academy)
and the electric potential for this is a constant value

Generally the half reaction for Al, Al3 half-cell is mathematically represented as
⇔ 
and the electric potential for this is constant value

Therefore the cell potential for an electrochemical cell is mathematically represented as

substituting values


Answer:
Endothermic hope that helps
Explanation:
Answer:
Moon I am guessing. Another option is comet, but they normally don't orbit a planet.
Answer:
The process of slowly adding one solution to another until the reaction between the two is complete.
Explanation:
When you perform a titration, you are slowly adding one solution of a known concentration called a titrant to a known volume of another solution of an unknown concentration until the reaction reaches neutralization, in which the reaction is no longer taking place. This is often indicated by a color change.
Hope that helps.
