Answer : The incorrect option is, (d) The reactant that was the smallest given mass is the limiting reagent.
Explanation :
Limiting reagent : It is the reagent that is completely consumed in the chemical reaction when the chemical reaction is complete. No amount is left after the reaction is complete. The amount of product obtained is determined by the limiting reagent. A balanced equation is necessary to determine which reactant is limiting reagent.
Excess reagent : It is the reagent that are not completely consumed in the chemical reaction. That means the reagent is in excess amount. Some amount of the excess reagent is left over after the reaction is complete.
From this we conclude that the options, A, B and C are correct. While the option D is incorrect.
Option D is incorrect because it is not necessary the reactant that was the smallest given mass is the limiting reagent but it is judge by the number of moles present in the reaction.
Hence, the incorrect option is, (d)

Answer:
Nitrogen (N)
Explanation:
From the question given above, the following data were obtained:
Electronic configuration of the element => 1s² 2s²2p³
Next, we shall determine the number of electrons present in the element.
Thus, the number of electrons in the element can be obtained as follow:
Number of electron = 2 + 2 + 3
Number of electron = 7
Next, we shall determine the number of protons in the element.
Since the element is neutral, the number of protons is the same as the number of electrons. Mathematically,
Number of protons = number of electrons
Number of electron = 7
Therefore,
Number of protons = 7
Finally, we shall determine the atomic number of the element.
The atomic number of an element is the number of protons in the atom of the element. Mathematically,
Atomic number = number of protons
Number of protons = 7
Therefore,
Atomic number = 7
Comparing the atomic number of the element ( i.e 7) with those in the periodic table, the name of the element is Nitrogen (N) since no two elements have the same atomic number.
