an acid is a molecule or ion capable of donating a proton or alternatively capable of forming a covalent bond with an electron pair

bases are substance which read with acid as originally proposed by G.F Rouelle in the mid-18th century

Explanation:

From the balanced equation: CaCl₂ + 2AgNO₃ → 2AgCl + Ca(NO₃)₂It is clear that 1.0 mole of CaCl₂ reacts with 2.0 moles of AgNO₃ to produce 2.0 moles of AgCl and 1.0 mole of Ca(NO₃)₂.The no. of moles of reacted (30.0 g) CaCl₂ = mass / molar mass = (30.0 g) / (110.98 g/mol) = 0.27 mol.

Using cross multiplication:

1.0 mole of CaCl₂ produces → 2.0 moles of AgCl, from the stichiometry.

0.27 mol of CaCl₂ produces → ??? moles of AgCl.

∴ The no. of moles of the produced AgCl = (2.0 mol)(0.27 mol) / (1.0 mol) = 0.54 mol.

∴ The mass of the produced AgCl = no. of moles x molar mass = (0.54 mol)(143.32 g/mol) = 77.48 g ≅ 77.5 g.
