How many moles of electrons are transferred when 4 moles of sodium (Na) react completely 2 Na(s) + H2(g) → 2 NaH (s) ?

Options

  1. A1 mole
  2. B2 moles
  3. C4 moles
  4. D8 moles

Correct answer

C. 4 moles

Step-by-step solution

For each mole of sodium reacting, 2 moles of electrons are transferred. Therefore, for 4 moles of sodium, 4 x 2 = 8 moles of electrons are transferred.
