The mussel shell erosion increased by 30 percent points between 1995 and 2020.
<h3>What is erosion?</h3>
Erosion is the washing away of the top layer of a substance or material.
The mussel shell erosion is a type of erosion which occurs in mussel shell as a results of chemical changes that occur on their environment.
The mussel shell erosion is shown on the graph.
Therefore, based on the graph, mussel shell erosion increased by 30 percent points between 1995 and 2020.

Answer: The product of the given reaction is 
and the solution at equilibrium will be acidic.
Explanation:
When two or more chemical substances react together then it forms new substances and these new substances are called products.
For example, 
This shows that nitric acid 
is the product formed and it is an acidic substance.
Hence, the solution at equilibrium will be acidic in nature.
Thus, we can conclude that the product of the given reaction is and the solution at equilibrium will be acidic.
