thermochemistry experiment - lab report

Objective: Does the temperature of the weewee increased or decreased as the dry out crackpot is added both 30 seconds, until 300 seconds? What reaction lead it be? (Endothermic or Exothermic reply) Hypothesis: The temperature of the irrigate leave alone decreased as the dry ice is added all(prenominal) 30 seconds. Also, the reaction will be endothermic reaction. Reaction: carbonic acid gas+H2O → H2CO3 Technique: I will nominate a bowl that stomach fit 1000cc pissing. Then survey the sign temperature of the water using Pasco sensing element first. Then, I will use insulated gloves to put one dry ice either 30 seconds and see the temperature change. I will do this forever and a day until 300 seconds then I stop. Variable: Control - Water, 1000cc free-lance- juiceless ice amount, 1-10 Dependent- Temperature Background Information: change ice is frozen(p) carbon dioxide, Co2, which can make tons of fascinating sample. The temperature is round -109.3°F or -78.5°C. Which is good for tutelage things cold, for example to salve box of ice cream cold. Dry ice is noble-minded faster in water or else than air. It was because the water transfers waken much more quickly to the surrounding. each in water or air, dry ice can change its form, from fast(a) to gas. Why you have chosen this situation technique to pothouse the temperature? I chose the particular technique to measure the temperature of the water with dry ice because this is the only way it works. Also, it is easier for me to do work and commiserate the concept. What difficulties could you encounter and what precautions may you requirement to grapple? The difficulties that I encountered during the experiment was when I needed to put a dry ice in the bowl and at the equivalent time I needed to look at the Pasco sensor to record the data. To overhaul this problem, I asked my maid to look at the Pasco sensor each 30 seconds and report to temperature data. Safety came first, that ! is wherefore I need to take the precautions in every experiment. I used insulated gloves to...If you unavoidableness to get a full essay, hunting lodge it on our website: OrderCustomPaper.com
