WebCR(OH)3 Web2 days ago · CaCO 3 + HCl = CaCl 2 + CO 2 + H 2 O. If we count up the number of each element on both the left-hand-side and right-hand-side, we see that all except Hydrogen and Chlorine are balanced. There is 1 H and 1 Cl on the left, but 2 of each the right. To balance H and Cl, we can put a 2 in front of HCl on the left-hand-side: CaCO 3 + 2 HCl = CaCl 2 ...

It can either gain a proton to form a hydronium ion H 3 O +, or else lose a proton to form a hydroxide ion OH −. Another possibility is the molecular autoionization reaction between two water molecules, in which one water molecule acts as an acid and another as a base. primary stakeholders คือ
