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. If there is a precipitation reaction, write the complete and net ionic equation that describes the reaction.
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.
Whenever I suggest contacts as an alternative to someone whoâs been wearing glasses for a while, I typically get some variation of the following reply: âContacts? No Way! I could never put anything like that in my eye.â People, itâs really not as bad as you think.he freedom of being able to see without glasses and not having to clean off your glasses several times a day is well worth getting over the fear of âputting something in your eyeâ! Laser Surgery (LASIK). LASIK surgery is all the rave nowadays to correct poor vision.
