 Let's do another example now. So our example this time is we're looking at sodium and chlorine making up sodium chloride So I'm using strawberries to represent sodium. I'm using chlorine again bananas to represent chlorine So let's fill up our shopping bags and see what we've got. So first thing we've got One strawberry goes in this bag representing that sodium and then in this bag here. We've got two chlorines again Put those in Right now on this side, we've got one sodium and one chlorine so one strawberry and one banana Put those in Right, there they go. So here's what we have to start with Let's count them up. So how many strawberries do we have on this side of the arrow? We've got one How many bananas do we have on this side of the arrow? We've got two so I'll put that second one in it All right, so on this side, we've got one strawberry and two bananas What about the other side? On the other side, we've only got one strawberry and one banana So I'll represent that as well. So I'll put one strawberry over here Replicating now now I've got one banana over this side. Okay. Is it balanced? Got one strawberry on this side one strawberry on this side. So that's okay I've got two chlorines on this side and only one chlorine on this side So two bananas on this side and one banana on that side. So what's the limiting factor here? I've got one banana on this side two bananas on this side So I need to have two bananas on this side So the way I'm going to do that is I'm going to double my number of bags on this side So now I've got two of these bags now. Let's count it up again one strawberry on this side That's okay two bananas on this side. So I'll replicate that one Okay, so there we go Now on the other side, let's count it up So we've got one strawberry on this side two strawberries on this side So two strawberries on the right side. So I put those in so we've got two strawberries on this side And how many bananas do I have on this side? Two put those in over here All right now, let's do a count up and see if we're balanced or not So I've got one strawberry two strawberries. So we're not so a limiting factor now is our number of strawberries So what we need to do is double our number of strawberries. Okay, so now we've got two strawberries on this side We can do that make sure we've got it right So two strawberries on this side two strawberries on this side two strawberries on the left two strawberries on the right and I've got two bananas on the left and two bananas on the right Put those in as well So the question is are we balanced now? So if we have a look at what we've got we've got two strawberries on this side two strawberries on this side Two bananas on this side two bananas on this side So now we're balanced because we've got the same number of strawberries and bananas on both sides of the area So on both the left hand and the right hand side of the arrow Now we need to represent that in our equation up here. So what we do what we did was we doubled the number of sodium So we doubled the number of strawberries. So right that over here So big two out front We didn't change the number of chlorines over here. They stayed at the same We didn't change that but what we did do is we doubled the number of sodium chlorides over here So again, I need to put a big two at the front And now that's fine. So this is how we would represent the balancing properly
