Answer:
(185 g Ca) / (40.0784 g Ca/mol) × (6.022 × 10^23 atoms/mol) = 2.78 × 10^24 atoms Ca
Explanation:
Explanation:
Net ionic between HCl and the buffer equation
CH3COOH --> acetic acid, CH3COO- acetate , H+ proton from HCl
there is neutralization of the acetate, and an increase in acid
the ionic equation
CH3COO-(aq) + H+(aq) + Cl-(aq) --> CH3COOH(aq) + Cl-(aq)
Net ionic:
CH3COO-(aq) + H+(aq) --> CH3COOH(aq).
Atoms are the elements in the compounds. Those reacting are called the reactants.

2(6) + 2(14) + 19(2)
= 12 + 28 + 38
= 78 atoms
