When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. caco3(s) + 2 hcl(aq) → cacl2 (aq) + h2o(1) + co2(8) how many grams of calcium chloride will be produced when 29.0 g of calcium carbonate is combined with 11.0 g of hydrochloric acid? mass of cacl,: 16.075 g which reactant is in excess? caco ohci how many grams of the excess reactant will remain after the reaction is complete? mass of excess reactant: 14.517

Explanation:

Given data:

Mass of CaCO₃ = 29.0 g

Mass of HCl = 11.0 g

Mass of CaCl₂ produced = ?

Which is excess reactant = ?

Mass remain unreacted = ?

Solution:

Chemical reaction:

CaCO₃ + 2HCl  →  CaCl₂ + H₂O + CO₂

Number of moles of CaCO₃:

Number of moles = mass/ molar mass

Number of moles = 29.0 g/ 100.1 g/mol

Number of moles = 0.3 mol

Number of moles of HCl:

Number of moles = mass/ molar mass

Number of moles = 11.0 g/36.5 g/mol

Number of moles = 0.3 mol

Now we will compare the moles of HCl and CaCO₃ with CaCl₂.

            HCl            :          CaCl₂

              2              :              1

               0.3         :            1/2×0.3 = 0.15 mol

             CaCO₃      :            CaCl₂

                   1           :            1

              0.3             ;         0.3

The number of moles of CaCl₂ produced by HCl are less so it will limiting reactant.

Mass of CaCl₂:

Mass = number of moles ×  molar mass

Mass = 0.15 mol × 111 g/mol

Mass = 16.65 g

CaCO₃ is present in excess.

            HCl             :         CaCO₃

              2               :            1

              0.3            :          1/2 ×0.3 = 0.15 mol

Mass remain unreacted:

Total moles of CaCO₃ = 0.3

Moles reacted = 0.15

Moles remain = 0.3 - 0.15 = 0.15 mol

Mass remain unreacted = 0.15 mol × molar mass

Mass remain unreacted =  0.15 mol × 100.1 g/mol

Mass remain unreacted = 15 g

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

it's filtration, but this is an assumption so my apologies if i got this
