<p>Anyone good with chem? I really need help; I'm trying to do my homework but I don't even know how to start. I'm just really confused. Can someone please tell me how to do this one problem, so I can know how to do the rest?? PLEASE! </p>
<p>CuCl + Ag(CH³CO²) --------> CuAg</p>
<p>That is all I have (the CuAg part). From there I am stuck.</p>
<p>I'm supposed to write net ionic equations for precipitation reactions.</p>
<p>You sure that's right? Copper Silver? ***?</p>
<p>Ag + Cl --> AgCl, more like.</p>
<p>Remember to note the charges for the elements.</p>
<p>lol two metals wouldn't bond together like that. the right equation is the one in post # 3...the silver chloride is the only thing that would precipitate out, the other product would exist as ions in solution</p>
<p>Ahh >.< Thanks for helping you guys.. Yeah I suck at chemistry...But I have a question. Why would (CH³CO²) be ions?</p>
<p>So:</p>
<p>CuCl + Ag(CH³CO²) --------> AgCl</p>
<p>And Cu & (CH³CO²) don't exist in the product?</p>
<p>The acetate ion is soluble with all cations (positive ions... metal ions). Copper chloride is soluble, too. The overall reaction would be:</p>
<p>Cu2+(aq) + 2Cl-(ag) + 2Ag+(aq) + 2CH3CO2-(aq) --> 2AgCl(s) + Cu2+(aq) + 2CH3CO2-(aq)</p>
<p>Copper and acetate are in exactly the same state on either side of the reaction-- they don't change form! So, you cancel them out of the equation. They're still present in the final solution, but they don't REACT, and the chemical equation is meant to represent the REACTION taking place. The coefficients on chloride and silver are all two, so you can just make them all one:</p>
<p>Ag+(aq) + Cl-(aq) --> AgCl(s)</p>
<p>This is called a metathesis reaction, and the pattern is easily recognized.
Mx= Metal Ion X; My= Metal Ion Y
Nx= Nonmetal Ion Y; Ny= Nonmetal Ion Y</p>
<p>MxNx + MyNy ---> MxNy + MyNx</p>
<p>The cations just switch anions.</p>
<p>Example:</p>
<p>Ba(OH)2(aq) + MgCl2(aq) --> Mg(OH)2(s) + BaCl2(aq)
^(not a net ionic equation)</p>
<p>Hope that helps!!</p>
<p>Ahhhhhhh! It all makes sense now lol! Thanks!</p>
