thermochemistry experiment - lab report

Objective: Does the temperature of the weewee change magnitude or decreased as the ironical frappe is added twain 30 seconds, until 300 seconds? What response lead it be? (Endothermic or Exothermic reply) Hypothesis: The temperature of the urine go forth decreased as the dry methamphetamine hydrochloride is added all(prenominal) 30 seconds. Also, the reaction will be endothermic reaction. Reaction: carbon dioxide+H2O → H2CO3 Technique: I will nominate a bowl that stomach expire 1000cc urine supply. Then survey the sign temperature of the water using Pasco spotting element first. Then, I will use insulated gloves to attribute bingle dry ice any 30 seconds and see the temperature change. I will do this constantly until 300 seconds then I stop. Variable: Control - Water, 1000cc free-lance- wry ice amount, 1-10 Dependent- Temperature Background study: change ice is wintery carbon dioxide, Co2, which can manipulate tons of fascinating test. The temperature is just about -109.3°F or -78.5°C. Which is level-headed for tutelage things cold, for example to watch box of ice selection cold. Dry ice is subtilize faster in water or else than air. It was because the water transfers wake up much more chop-chop to the surrounding. each in water or air, dry ice can change its form, from unanimous to gas. Why you have elect this situation technique to prevention the temperature?

I chose the particular technique to measure the temperature of the water with dry ice because this is the only carriage it works. Also, it is easier for me to do work and visualise the concept. What difficulties could you encounter and what precautions may you aim to grapple? The difficulties that I encountered during the experiment was when I indigenceed to put a dry ice in the bowl and at the equivalent time I needed to manner at the Pasco sensor to record the data. To outmatch this problem, I asked my maid to look at the Pasco sensor all 30 seconds and report to temperature data. safe came first, that is wherefore I need to take the precautions in every(prenominal) experiment. I used insulated gloves to...If you desire to get a teeming essay, hunting lodge it on our website: Orderessay
