Can antimony pentafluoride be made by adding hydrogen fluoride to antimony trifluoride?
I was looking at how the strongest acid was made and I found something I did not understand. On the Wikipedia page for antimony trifluoride it shows the production of $\ce{SbF3}$ using $\ce{HF}$:
$$\...

Net ionic equation for a synthesis reaction?
In the following reaction
$$\ce{S (s) + O2 (g) -> SO2 (g)}$$
there are no spectator ions because both $\ce{S}$ and $\ce{O2}$ take part in the reaction. Does that mean the net ionic equation is ...
