Answer:
2Na + I₂ → 2NaI. "Synthesis reaction"
Step-by-step 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).
