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.
In some people, bloodshot eyes can be the result of contact lens wear. The lenses sometimes cause the eye to become dry, which leads to redness and irritation. In those cases, use of a special moisturizing drop for contact lens wearers can bring relief.n some people, bloodshot eyes can be the result of contact lens wear.
