I followed my safety precautions by wearing goggles at all times‚ washing my hands after the experiment and I was very cautious when handling acid. I got one anomalous result which is pointed out on my graph showing rate of reactions‚ I think this is due to one of the three tests being to different

Materials: The materials that were used were Aluminum wire(12 cm)‚ beaker (100 mL)‚ hot plate‚ copper(II) nitrate (1.0 M)‚ glass stirring rod‚ gloves‚ HCl (1.0 M)‚ lab apron ‚ lab marker‚ NaOH (1.0 M)‚ ruler‚ safety goggles‚ test tube (13 mm x 100mm) and test tube rack. Procedure: Safety goggles‚ gloves‚ and lab apron were put on. (Only the ones who were doing the experiment) 50mL of water was placed in the 100mL beaker and heated until boiled. And the boiled water will be used as the water bath. The lab

door where I found a stand-up tanning bed. I decided this was a perfect opportunity to get a few more tanning minutes. I set the timer for a full twenty minutes and began to tan. While you are using a tanning bed‚ you are suppose to wear goggles. I did not have goggles‚ and I was not surrounded by the bed‚ so I was not thinking about the bulbs affecting my eyes. Later that night I decided to go home‚ and I would go back to the house in the morning. As soon as I got home I took a shower‚ and the water

hazards you may encounter. Think again! On impact‚ regular lenses tend to shatter more easily. Safety lenses may shatter‚ but they require a much greater impact. Various types of eye protective devices have been designed‚ including safety glasses‚ goggles and full-face shields. Their uses differ according to the type of work. You should always wear the type of eye protection recommended for the work you are

it wouldn’t be fair as no cube will be exactly the same size. In conclusion to this experiment‚ 0.5M of acid was the best to use as it had the best measurable reaction time. Equipment The equipment we will be using during this experiment is: *Goggles (to protect the eyes from reactions) *Measuring cylinder (to measure out the acid) *Bunsen burner (to heat the acid to the right temperature) *Test tubes (to hold first experiment in) *Hydrochloric acid (the acid being used) *Powdered limestone
