 Is it gone? Okay, cool. So this one says which member of each pair, or which member of this pair is the stronger acid? Can you tell me if I'm remembering the rules? The second one. Yeah, the second one. If you remember the rule, right? It has more oxygen. Yeah, two or more oxygens than ionizable protons. So in this case, we got the number of oxygens is three oxygens, and we have one hydrogen. So if we look at that, right, we have two more oxygens than hydrogens, right? So here, let's write it like this. Two more oxygens, hydrogens. Okay, so if we have that, two or more, in fact, that's a strong. And then this one, is this one going to be a strong acid? No, it's going to be a weak acid, remember? So this is a weak acid. And it's because of the other side of this rule. If you have less than two oxygens per ionizable proton, then you're a weak acid. Okay, so less than two weak acid, more than two, or two or more strong acid. Okay, any questions on that one? Okay, cool. You want to get it?
