So if i have the equation

2 SO3 --> 2S + 3 O2

would my word equation for this be Sulfur Oxide --> Sulfur + Oxygen OR
Sulfur hexaoxide --> Sulfur + hexaoxide

or what would be the correct one if both are wrong?

and for this one
2 KI + MgCI2 --> MgI2 + 2KCL
Potassium Iodide + Magnesium dichloride --> magnesium diIodide + potassium Chloride (that's my guess)

Btw i added all the Coefficients to make the equations balanced

2 answers

sulfur trioxide ==> sulfur + oxygen

The second equation will not react to produce anything. The names are potaqssium iodide + magnesium chloride --> Magnesium iodide + potassium chloride.
Oh okay, i was thinking it could've been trioxide cause of the subscript, thank you.
