Use the balanced equation to solve the problem.
harkovskaia [24]

Answer:

4.20 moles NF₃

Explanation:

To convert between moles of N₂ and NF₃, you need to use the mole-to-mole ratio from the balanced equation. This ratio consists of the coefficients of both molecules from the balanced equation. The molecule you are converting from (N₂) should be in the denominator of the ratio because this allows for the cancellation of units. The final answer should have 3 sig figs because the given value (2.10 moles) has 3 sig figs.

1 N₂ + 3 F₂ ---> 2 NF₃

2.10 moles N₂        2 moles NF₃
---------------------  x  ---------------------  =  4.20 moles NF₃
                                  1 mole N₂

In a spontaneous fusion reaction, the total mass of the products is ________________________ the mass of the original elements.
Mice21 [21]
I believe the correct term that would fit the statement would be greater than. In a spontaneous fusion reaction, the total mass of the products is greater than the mass of the original elements. This nuclear reaction involves at least two nuclei that fuses to form one nuclei having larger mass than that of the reactant.
