How do you know if he likes you?

If you mean romantically, you can look at his eyes and if they dilate while looking at you he probably likes you. The best way is just to be open with your feelings ^^

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 !
