(a)
Interpretation:
When magnesium of mass 0.121 g is dissolved in 50.0 mL of 1.00 M HCl, some amount of
Concept Introduction:
Limiting reagent is the reactant that limits the amount of product produced in a
(b)
Interpretation:
The volume of HCl in mL needs to be calculated at given temperature and pressure.
Concept Introduction:
From the
Here, n is number of moles, R is Universal gas constant, T is temperature and P is pressure of the gas.
(c)
Interpretation:
The joules of energy released by the magnesium needs to be determined.
Concept Introduction:
Heat produced can be calculated as follows:
Where m is the mass, s is the specific heat capacity, delta T is the change in temperature.
The mass of the substance is related to number of moles and molar mass as follows:
(d)
Interpretation:
The heat of reaction for magnesium needs to be calculated in joules/gram and in kilojoules/mol.
Concept Introduction:
Heat released in J/g =
Heat released in kJ/mol =
1kJ = 1000J
