Question

Given the following balanced reaction:

2 Na (s)+1F^2(g)→2NaF (s)

(a) How many moles of NaF will be made from 2.6 moles of F2?
(a) 5.2 moles
(b) 2.6 moles
(c) 1.3 moles
(d) 10.4 moles

Answer 1

To find the moles of NaF produced from 2.6 moles of F2, we use the stoichiometry of the balanced chemical reaction, indicating that 2.6 moles of F2 produce 5.2 moles of NaF. Therefore, the correct answer is 5.2 moles of NaF (option a).

Step-by-step explanation:

To determine the number of moles of NaF produced from 2.6 moles of F2, we can use the stoichiometry of the balanced chemical equation: 2 Na (s) + F2(g) → 2 NaF (s). According to this equation, 1 mole of F2 yields 2 moles of NaF. Therefore, if we start with 2.6 moles of F2:

• 2.6 moles of F2 × (2 moles of NaF / 1 mole of F2) = 5.2 moles of NaF.

Thus, the correct answer is option (a) 5.2 moles of NaF.
