EXAMPLE 1 â Predicting Precipitation Reactions: Predict whether a precipitate will form when water solutions of silver nitrate, AgNO 3 (aq), and sodium sulfide, Na 2 S(aq), are mixed. If there is a precipitation reaction, write the complete and net ionic equation that describes the reaction. he following is a typical problem. Predict whether a precipitate will form when water solutions of silver nitrate, AgNO 3 (aq), and sodium sulfide, Na 2 S(aq), are mixed.

Symptoms include: itching, burning, redness and swelling. Treatment may include antibiotic or anti-allergy eye drops. Contact lens rewetting and eye surface lubrication. If your eyes sometimes feel dry wearing contact lenses, choose eye drops specifically intended for use with contacts. Other drops could discolour your contacts or temporarily change their fit.
He said that if it was Astigmatism causing the distance fuzziness that eye drops wouldnt momentarily clear up my vision. Now I think I know why my toric contact lenses were torture to wear after 3 hours, I was having dry eyes from them. Thats the main reason I decided to get lasik, because contacts were just to uncomfortable. When I put in lubricating eye drops my vision is awesome, just like I hoped for. But as soon as the drops wear off, like aprox 3 mins my vision is not crisp. Also, be careful about eye drops with preservatives.
