The lithosphere (under the tectonic plates) is semifluid, allowing for the plates above to move over it, causing earthquakes, and essentially continental drift.
W(N)={2M(N)/M(NH₄NO₃)}*100%
w(N)={2*14.0 g/mol/80.0 g/mol}*100% = 35%
Answer : The balanced molecular equation will be:

Explanation :
Molecular equation : It is a balanced chemical reaction in which the ionic compounds are expressed as the molecules instead of component ions.
According to the question, when iron react with copper (II) sulfate then it react to give iron (II) sulfate and copper as a product. In this reaction, iron is more reactive metal than the copper metal. So, it can easily displace copper metal form the solution.
The balanced molecular equation will be:

Answer:
90.26%
Explanation:
From the question given above, the following data were obtained:
Theoretical yield of AlCl₃ = 1551 g
Actual yield of AlCl₃ = 1400 g
Percentage yield =?
The percentage yield of the reaction can be obtained as follow:
Percentage yield = Actual yield / Theoretical yield × 100
Percentage yield = 1400 / 1551 × 100
Percentage yield = 140000 / 1551
Percentage yield = 90.26%
Thus, the percentage yield of the reaction is 90.26%
