When sodium reacts with chlorine, sodium chloride is produced. andrew represented this reaction with this equation:
na + cl2 → 2nacl
the equation is (blank 1) because the number of (blank 2) atoms is (blank 3) on both sides of the arrow.
blank 1
a) balanced
b) not balanced
blank 2
a) chlorine
b) sodium
blank 3
a) equal
b) not equal

B) Not Balanced

B) Sodium

B) Not Equal

The equation is not balanced because the number of sodium atoms is not equal on both sides of the arrow.

2Na + Cl2 → 2NaCl
