It;s a physical change because the tablet dissolved and it made the water cooler
Explanation:
The boiling point of alcohols also increase as the length of hydrocarbon chain increases
Answer:
The balanced half reaction in an acidic medium is :

Explanation:

While balancing the half-reaction in an acidic medium, we will first balance oxygen atoms by adding water:
1) Adding 1 water molecule on product side to balance oxygen atoms.

Now balance hydrogen atom by adding
.
2) Adding 2 hydrogen ions on reactant side to balance hydrogen atoms.

Now balance the charge adding electrons on the side where positive charge is mor.
3) Adding 1 electrons on reactant side to balance charge of the overall reaction:

The balanced half reaction in an acidic medium is :

Number 1 is 4.875 Number 2 is 3.47 repeating
