Which of the following equations is balanced? Question 2 options: Na + 2Cl2 → 2NaCl Na + Cl2 → NaCl 2Na + Cl2 → NaCl 2Na + Cl2 → 2NaCl

The equation which is balanced is

2Na + Cl2→ 2 NaCl

Explanation

According to the law of mass conservation in a chemical reaction, the number of atoms in the reactants side must be equal to number of atoms in product side.

The reaction above is balanced since it obey the law of mass conservation.

for example there is 2 atoms of Na in reactant side and 2 atoms of Na in product side.
