The solubility product constant of calcium sulfate, CaSO4, is 7.10×10−57.10×10−5. Its molar mass is 136.1 g/mol. How many grams of calcium sulfate can dissolve in 75.5 L of pure water

2)

Explanation:  When an acid reacts with the base then it undergoes neutralization to form a salt and water.

1) : is an example of single replacement reaction as Mg replaces hydrogen from its salt solution.

2) : is an example of neutralization where acid and base reacts to give salt and water.

3) :  is an example of double displacement reaction in which exchange of ions take place.

4) : is an example of decomposition where a single reactant decomposes to give two or more products.
