Question

Predict whether a chemical reaction occurs and write the balanced molecular equation.

Ag₂SO₄ (aq) + KCl (aq) →

Accepted Answer

here in this practice question, it says predict whether a chemical reaction occurs and right the balance molecular equation. So hero given silver sulfate and potassium chloride. So Step one tells us that we need to break it up into its ions. So we have silver and sulfate. Don't worry about the fact that there's two silvers. They're just break it up into its ions. Silver is plus one. It's a transition metal, but it's charges always plus one. Seoul fate is a poly atomic ions, or two minus potassium is in Group one A. So it's plus one, and chlorine is in group seven, A sorts minus one. Now remember, we're going to swamp Ionic Partners. Opposite charges attract this plus one and this minus one for about the l. This minus one are attracted to each other, so their numbers are exactly the same in terms of their charges. When they're the same, they just cancel out. So here will have a G CEO plus here the numbers and the charges were not the same. When they're not the same, they don't cancel out. Instead, they crisscross. So, too comes here. One comes here, so it's gonna give me K two s Now we have to determine if a reaction has occurred. And it only occurs if we create a solid a gas or liquid water. If we think back on our salt ability rules. So silver. There is no rule for silver from Ghana. Kasher cops. But there is a rule for chlorine. Chlorine is a halogen, right? We know that from Ghana. Cash Halogen do have exceptions, right? So there are exceptions are happy. If they're connected to mercury, silver or lead, they will not be soluble. They will be insoluble and make a precipitate here. Chlorine. My halogen is connected to silver. So it's not gonna be soluble. It's gonna be a solid. So we know reaction has occurred because we've created a solid not let's look at the other one. We have potassium sulfate. So potassium, his group one a group one A. Elements, if they're connected to anybody, doesn't matter. They're always gonna be soluble. So we don't even need to look at the Saudi ability rule for sulfite sulfate. Because by default, the whole thing is soluble because of the presence of potassium. So here goes our equation. Now we have to balance it. Here we have two silvers, but here we only have one. So I'm gonna put it to here. Next we have one sulfate, one sulfate. Then we have if we look to get distributed to chlorine, so we have to chlorine. And then we have two potassium here. So that means I have to put a two right here. Now, every element within this structure is balanced. So now we're gonna save my coefficients. Would be 1 to 2 and one. So this represents my balance. Molecular equals.
