8.which set of coefficients would
correctly balance the equation?
nacl o na + cl2
a. 1,1,2 b. 1, 2,1
c.2, 1, 2 d. 2, 2, 1

The set of coefficients that would correctly balanced the equation

NaCl → Na + Cl2   is the option D

(2,2,1)

Explanation:

In this reaction sodium chloride splits into sodium and chlorine.

For balancing the equation we should have number of atom of the element in the left hand side equal to the number of atom of the same element in the right-hand side.

so here in left hand side only one sodium and one chlorine is given and in the right-hand side one sodium and two chlorine is given.

So for the balancing the equation both the side should be same.

So we will write the balanced equation as

2NaCl → 2Na + Cl2

So, right now it is balanced that is two sodium and two chlorine on the left hand side as well as the right hand side.

Hence the coefficients are

2, 2, 1

are their multiple choices ?
