Sodium (Na) and iodine gas (I2) react to form sodium iodine (NaI).
Which equation is a correct representation of the balanced equation?
Responses
Na→NaI+I2
upper case N lower case A rightwards arrow upper case N lower case A upper case I plus upper case I subscript 2 end subscript
NaI→2Na+I2
upper case N lower case A upper case I rightwards arrow 2 upper case N lower case A plus upper case I subscript 2 end subscript
2Na+I2→2NaI
2 upper case N lower case A plus upper case I subscript 2 end subscript rightwards arrow 2 upper case N lower case A upper case I
I2→2NaI+2Na
