1. What do producers do, and what is another name for them?

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

Your question is not clear but if you can explain yourself i would be glad to .  just trying to : ))
