Answer: False
Explanation: Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate
According to the Aufbau principle, , electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels (e.g., 1s before 2s).
Following the atomic mass of each of these atoms, we have 1 Fe atom with 56 amu, 3 N atoms with 14 each, and 9 O atoms with atomic mass 16. Adding these together, we get 56 + 42 + 144 = 144 + 98 = 242. Your answer is (4) 242 g/mol
