Question

This formula equation is unbalanced. BaCl2(aq) + Na2CO3(aq) mc017-1.jpg BaCO3(s) + NaCl(aq) Which coefficient should be placed in front of NaCl to balance this equation? 1 2 3 4

Answer 1

You would need to put a 2 in front of NaCl.

Hope this helps!!

Answer 2

BaCl2(aq) + Na2CO3(aq) → BaCO3 (s) + NaCl(aq)

The coefficient that should be placed in front of NaCl to balance the equation above is 2

The balanced equation is as below

BaCl(aq) + Na2CO3 (aq)→ BaCO3 (s) + 2NaCl (aq)

Step-by-step explanation

According to law of mass conversation the number of atoms of an element must be equal in both side of reaction.

By adding 2 in front of NaCl ensures that the number of each element is equal in both side.

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