Zn (s) + 2HCI (aq) -- H2 (g) + ZnCI2 (s)

perchloric acid
Dichlorine heptoxide is the anhydride of perchloric acid. Cl2O7 + H2O ---> 2HClO4
2HClO4(aq)+Li2CO3(aq)→H2O(l)+CO2(g)+2LiClO4(aq)
HClO4 (acid) (aq) + H2O (base) = CLO4- (conj. base) (aq) + H3O+ (conj. acid) (aq)
K2SO4+ClH K++ClO4-+H22++SO4- (arrow pointing to the right) K2SO4+ClH Sorry i disagree. 2K+ + 2ClO4- + 2H+ + SO42- -> 2HClO4 + 2K+ + SO42- Perchloric acid is normally made by reacting potassium perchlorate with hydrochloric acid
