Question
Calcium nitrate and ammonium fluoride react to form calcium fluoride, dinitrogen monoxide, and water vapor. What mass of each substance is present after 16.8 g of calcium nitrate and 17.50 g of ammonium fluoride react completely?
Step-by-Step Solution
Verified(a) The mass of left is 9.91 g.
(b) The mass of left is 0 g.
(c) The mass of is 7.99 g.
(d) The mass of is 9.01 g.
(e) The mass of is 7.38 g.
In a balanced chemical equation, the number of atoms on the reactant side should be the same as the number of atoms on the product side for a particular atom. For balancing the reaction, the atoms are multiplied by the stoichiometric coefficient.
So, the balanced chemical equation is:
The number of moles is calculated by the mass and Molar mass. The relationship between the number of moles, mass, and molar mass is given below.
The mass of= 16.8 g.
The molar mass of= 164.1 g/mol
Thus, the number of moles ofis:
The mass of = 17.5 g.
The molar mass of = 37.037 g/mol
Thus, the number of moles of is:
In the given reaction, 1 mol of reacts with 2 mol of
Thus,
In the reaction, 1 mol of reacts with 2 mol of Thus,
Therefore, present in access in the reaction, hence is a limiting reagent.
The molar mass of = 78.07 g/mol
The number of moles left = 0.4725 mol – 0.02048 mol = 0.2677 mol
Thus, the mass of left is:
Since is completely utilized in the reactions, thus zero moles of is left in the reaction. Hence, the mass of is zero.
In the given reaction, 1 mol of forms 1 mol of
Thus, the number of moles of is
The molar mass of = 78.07 g/mol
Thus, the number of moles of is:
In the given reaction, 1 mol of forms 2 mol of
Thus, the number of moles of is
The molar mass of = 44.013 g/mol
Thus, the number of moles of is:
In the given reaction, 1 mol of forms 2 mol of
Thus, the number of moles of is
The molar mass of = 18.02 g/mol
Thus, the number of moles of is:
