The balanced chemical reaction is given as:
Now, convert into litres.
So,
Density is equal to the ratio of mass to the volume.
where, M = mass and V= volume
Substitute the value of density and volume in formula to get the value of mass.
Now, number of moles of gas=
=
According to the reaction, 2 moles of sodium azide gives 3 moles of nitrogen gas.
Now, in 24.00 moles of nitrogen gas produced from= of nitrogen gas, moles of sodium azide.
number of moles of sodium azide =
Mass of sodium azide in g = .
=
=
Thus, mass of sodium azide which is required to produce of nitrogen gas =
Answer: a) : Decomposition
b) : double displacement
c) : Synthesis (Combination)
d) : redox
Explanation:
Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
A double displacement reaction is one in which exchange of ions take place.
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Redox reaction is a type of chemical reaction in which oxidation and reduction takes place in one single reaction. The oxidation number of one element increases and the oxidation number of other element decreases.
