Answer:

2Na + I₂ → 2NaI. "Synthesis reaction"

Explanation:

  • To balance the equation, you should apply the law of conservation of mass for the equations.

  • The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).

  • The balanced equation is:

2Na + I₂ → 2NaI.

It is a synthesis reaction that 2 reactants give 1 product.

That 2.0 mole of Na combined with 1.0 mole of I₂ to produce 2.0 moles of NaI.

The no. of all atoms is the same in both of reactants and products side.

Na (2), and I (2).
