Hello!
The dissociation reaction of HNO₃ is the following:
HNO₃ → H⁺ + NO₃⁻
This is a strong acid, so the concentration of HNO₃ would be the same as the concentration of H⁺. The formula for pH is the following:
![pH=-log([H_3O^{+}])=-log(0,75M)=0,12](https://tex.z-dn.net/?f=pH%3D-log%28%5BH_3O%5E%7B%2B%7D%5D%29%3D-log%280%2C75M%29%3D0%2C12)
So, the pH would be 0,12
Have a nice day!

Answer:
The amount of calcium carbonate will increase.
Explanation:
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
- K>Q , reaction will move forward by making more product.
- K<Q , reaction will move backward by making more reactant.
Equilibrium constant of the reaction =
Concentration of
Concentration of
Concentration of
This means that equilibrium will move in backward direction by which amount of calcium carbonate will increase.
