Answer:
H2SO4 (aq) + Ca(OH)2 (aq) ----> CaSO4 (aq) + H2O(l)
HClO4 (aq) + KOH (aq) -----> KClO4 (aq) + H2O (l)
H2SO4 (aq) + NaOH (aq) -----> Na2SO4 (aq) + H2O(l)
Explanation:
An acid reacts with a base/alkali to form a salt and water as its product. The type of base/alkali determines if there would be any extra products. For example, in the case of trioxocarbonates and hydrogen trioxocarbonates (iv) , carbon iv oxide is formed alongside.
The balanced chemical equation of the reactions is given below;
H2SO4 (aq) + Ca(OH)2 (aq) ----> CaSO4 (aq) + H2O(l)
HClO4 (aq) + KOH (aq) -----> KClO4 (aq) + H2O (l)
H2SO4 (aq) + NaOH (aq) -----> Na2SO4 (aq) + H2O(l)
