 Okay, so let's do a lot an easy one for the last one of the day I am reacts with oxygen gas Okay to form this iron oxide Okay, so First thing we do is what? right in the atoms, right? so we've got Iron on this side and oxygen on this side, right on this side. We also have Iron and oxygen how many irons do we have here? One and how many oxygen? two How many irons? three How many irons? Oh, oxygens Now I'm being like Okay, so Well, what do we have to do so there's only irons over here, right? So what do we have to do to this iron to make it three? Yeah, just multiply by three That equals three. So where are we going to put that three? Very good the coefficient very good, okay, and Oxygen over here is four, but we have two oxygens here. So what do we have to do to our two? multiply by two That equals four and what do we do with that two? Right because two times two equals four, okay So don't get freaked out and Now last just to make sure right I want to say three and three right so we're balanced there Four and four so we're balanced A little more basic one I think
