What would observe during this chemical reaction that would indicate a reaction is taking place? Nadl + AgNO, > NaNO, + AgCI (s) 5. A student performs an experiment to determine what happens when you mix vinegar (acetic acid) with baking soda (sodium bicarbonate). He varies the amount of vinegar he mixes with baking soda while also varying the temperature at which he mixes the substances. Evaluate the student's experiment. Identify any errors the student made in the setup of the investigation. 6. In some chemical reactions, light is produced or temperature changes. What is going on between the substances in the reaction? What would cause these things to occur? 7. Why is it important to never mix unknown substances together, especially in a science classroom during a laboratory? 8.

Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 8 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000054 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL Do not include units with your answer.
