Heat Ap Chemistry Lab

Heat is a form of energy. The lab that was conducted explored temperature change, which is a measure of heat. In a system, heat is constantly trying to stabilize throughout. For example, when the temperature probe was at room temperature and it was placed in a hot cup of water, the metal on the temperature probe increased, and the temperature reading increased. When the probe was placed in cold water, the heat from the metal was lost to the system and the temperature reading went down. It was found that the temperature probe took roughly 20 seconds to conform to the system’s temperature (figure 1). A possible way to increase or decrease that time would be to change the material that the temperature probe was made out

The Specific Heat of Lead

...Smith AP Chemistry 28 November 2012 I. Introduction A. Reference: Mr. Smith’s Instructions B. Problem: To calculate the specific heat of Lead. C. Hypothesis: If the heat absorbed by water when lead is added is known then the specific heat of lead can be calculated. D. Theory: i. In this experiment it is assumed that the density of liquid water is 1.00 g/mL ii. The equation qlost = -qgained can be applied when the change in temperature of the water is calculated. The energy gained by the water is equal to the energy lost by the lead. iii. The equation q =m ×Cp ×∆T can be simplified to solve for lead’s specific heat (Cp) once the heat of lead (q) is solved for using the equation shown in (ii). E. Variables: i. Independent: type of metal (Pb) ii. Dependent: final temperature of water iii. Control: temperature and pressure of the lab environment, the volume of water II. Experimental Design A. Equipment: i. Hot plate ii. 200 mL tap water iii. Balance iv. Styrofoam calorimeter v. 250 mL beaker vi. Test tube vii. Lab Quest viii. Lab Quest temperature probe ix. Test tube clamp B. Chemicals: metal shot (Lead - Pb) C. Apparatus: D. Method: i. Heat 150 mL water in the 250 mL beaker on the hot plate at its highest setting ii. Add the metal (Pb) shots into the test tube and place the test tube into the heating water iii. When the water boils, turn down the heat setting...

Ap Chemistry Assignment On Filter Paper

...Kevin Chen Part 3 Ap Chemistry I have completed this assignment on my own. I have not discussed this assignment with anyone except Ms. Chubbuck. I have neither given nor received assistance in completing these tasks. Kevin Chen 1). How to fold filter paper and how to filter a solid from a solution: Gravity Filtration: Select the correct size of filter paper and fold the filter paper into a cone by folding it in half and then again. Place the filter paper in the opening of the Erlenmeyer flask, wet the paper with a little of the solution, and pour the solution.

...THERMOCHEMISTRY OF NaOH AND HCl LAB Overview Teacher’s Instruction: Find the Molar Heat of Reaction for the NaOH reaction. Then, predict and calculate the change in enthalpy (ΔE) and change in heat (ΔH) when 5.00g NaOH reacts completely with HCl. Reaction Equation: NaOH(s) + HCl(aq) -> NaCl(aq) + H2O(liq) Net Ionic Equation: Na(OH)(s) + H+(aq) -> H2O(liq) + Na+(aq) The Big Question: If we combine solid NaOH and aqueous HCl, how will the temperature change? What will the change be with, specifically, 5.00g of NaOH? Scientific Background and Principle: WELL, I’ll have you know that we got our hands on a fancy-schmancy Lab Quest 2 with a temperature probe. Now this device allows us to accurately record the temperature of a given entity over a period of time; as such, by having the Lab Quest record the temperature of the system, we were able to gather the total temperature change for the reaction. In theory, the temperature should increase by 53.10o Variables * Independent Variable: Amount of NaOH * We had a theoretical value for temperature that was dependent on the amount of NaOH used; as such, we set our amount at a certain point to achieve that temperature. * Dependent Variable: Heat of Reaction (Temperature) * We measured the temperature of the reaction throughout its duration, which would have varied in intensity and duration based on the amount of NaOH we used * Controlled Variables * Light-- by enclosing the reaction in darkness...

Nitrate Reduction Test

...Current tests for nitrate and nitrite reduction are based on the Griess diazotization reaction described in 1858 by Peter Griess. Griess was raised on a farm in Prussia and was the son of a blacksmith, but “…tilling the soil was little to his liking, and on more than one occasion his father found him in a corner of the field, deep in a book, seated on the plough.” (25) In his early attempts at higher education, he was far from a model student, spending time in the institution’s prison and eventually expelled for a year. Finally, in his 6th year at university he began to seriously study chemistry. He obtained employment in the coal-tar distillery where the senior chemists discovered and developed the aniline dye industry. Even though the distillery was soon destroyed by fire, Griess had become obsessed with the chemistry of dye making. He was recommended for a position at the Royal College of Chemistry in Great Britain on the very day that his first article on possible diazo compounds appeared in print: “A Preliminary Notice on the Influence of Nitrous Acid on Aminonitro- and Aminodinitrophenol.” Griess’ first several attempts at diazotization exploded, but his commission at the Royal College was to investigate his new nitrogen intermediates, with the result that diazobenzoic acid was isolated and an entirely new class of compounds was discovered.(18, 25) Because many of these compounds were found to be stable and could be used for dying fabric without needing a mordant, he is heralded...

Cars

...Breaking Into Cars—Stephen I had never broken into a car before. We were in Laredo, having just finished our first day at a Habitat for Humanity work site. The Hotchkiss volunteers had already left, off to enjoy some Texas BBQ, leaving me behind with the college kids to clean up. Not until we were stranded did we realize we were locked out of the van. Someone picked a coat hanger out of the dumpster, handed it to me, and took a few steps back. “Can you do that thing with a coat hanger to unlock it?” “Why me?” I thought. More out of amusement than optimism, I gave it a try. I slid the hanger into the window’s seal like I’d seen on crime shows, and spent a few minutes jiggling the apparatus around the inside of the frame. Suddenly, two things simultaneously clicked. One was the lock on the door. (I actually succeeded in springing it.) The other was the realization that I’d been in this type of situation before. In fact, I’d been born into this type of situation. My upbringing has numbed me to unpredictability and chaos. With a family of seven, my home was loud, messy, and spottily supervised. My siblings arguing, the dog barking, the phone ringing—all meant my house was functioning normally. My Dad, a retired Navy pilot, was away half the time. When he was home, he had a parenting style something like a drill sergeant. At the age of nine, I learned how to clear burning oil from the surface of water. My Dad considered this a critical life skill—you know, in case my aircraft...
