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

Respuesta :

 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.

The balanced equation is 2 Na + Cl₂ → 2 NaCl.

According to Lavoisier's law of conservation of mass, the number of atoms on the left side of the reaction must be equal to the number of atoms on the right side, for the reaction to be balanced.

Which of the following equations is balanced?

  • Na + 2 Cl₂ → 2 NaCl

No, since there is 1 Na atom on the left side and 2 Na atoms on the right side.

  • Na + Cl₂ → NaCl

No, since there are 2 Cl atoms on the left side and 1 Cl atom on the right side.

  • 2 Na + Cl₂ → NaCl

No, since there are 2 Na atoms on the left side and 1 Na atom on the right side.

  • 2 Na + Cl₂ → 2 NaCl

Yes, the equation is balanced.

The balanced equation is 2 Na + Cl₂ → 2 NaCl.
