Objective: To determine how think a piece of aluminum foil and how many atoms are stacked up to make that thickness of the foil. Introduction: To be able to complete the experiment one must understand the basis of the period table such as the location of the elements and deciphering from a metal and a non-metal, as well as identifying the atomic mass and atomic number of an element. One must have knowledge of the mathematics of destiny which is defined as mass dived by volume to perform a dimensional analysis. Dimensional analysis is a problem-solving method that uses the concept that any number or expression can be multiplied by one without changing its value and converting information into the correct annotation. From the handout it states that, “approximately 2.7 million hydrogen …show more content…
Procedure: With all materials needed, proceed to use the aluminum block to determine the mass and then record in a table. Then fill the graduated cylinder halfway with water and record the volume of the water precisely. Tip the cylinder gradually being cations as not to spill and slide the aluminum block into the graduated cylinder. Put the cylinder straight up and confirm the block is absolutely submerged. Afterwards record the volume. Extract the aluminum block from the cylinder and dispose of the remaining water and clean the cylinder before storing it away. For the second half of the experiment retrieve a single piece of aluminum foil and cut out a 15cm x 15cm square. Then calculate the width and length of the foil and record the data in the table. Finally determine the mass of the piece of aluminum foil and record it. Results: Quantitative Results water rises with aluminum block water without block aluminum block graduated
Topic: What’s Better Aluminum or Wood bat? With baseball being one of the most popular sports on the planet, many people are familiar with the different types of bats, which are wood and aluminum. Though many people argue the aluminum bat is better it rises the question, which is truly better, wood or aluminum? This papers will focus on the analysis of wood and aluminum bats.
After the water temperature began to stabilize, the highest constant temperature was recorded. This data was used to calculate the calorimeter constant. This enter procedure was repeated to calculate another calorimeter constant in order to find the average of both answers. After that value was calculated, a 600 mL beaker was filled with 300 mL of water and heated till it started boiling. An unknown metal located on the instructor's bench was obtained and the mass was calculated.
Fill beaker with water Use the disposable pipette to place water in the graduated cylinder until the unidentified object would be completely submerged in water Record what the measurement of water in milliliters before placing the unidentified object into the graduated cylinder Gently place the unidentified object into the graduated cylinder Record the measurement of the water in milliliters after placing the unidentified object into the graduated cylinder Subtract the measurement of water in milliliters before placing the unidentified object into the graduated cylinder from the measurement of the water in milliliters after placing the unidentified object into the graduated cylinder, this is the volume of the unidentified object Record the volume (the answer you got in step 10) of the unidentified object in the data table Weigh the unidentified object on the scale, this is the mass of the unidentified object Record that number in the data table Calculate the density of the object by dividing the mass by the volume and rounding it to the proper significant figure, Record the density of the unidentified object in the data table Repeat the lab 2 more times and with each experiment record the data in the chart under the correct trial number corresponding with the correct
By reading the new volume of the liquid substance amount one will then subtract the initial milliliter amount from the final volume reading, thus giving you the volume of the rock sample. Using the mass of the sample rock obtained one will then divide the final volume reading unveiling the density of the
Characteristic Property- Test 2- Density Materials: Triple Beam balance, distilled water, graduated cylinder, unknown 6 Procedure: first we found the mass of the empty graduated cylinder and then its mass with the now distilled unknown. After subtracting the mass of the graduated cylinder, we were able to find the volume. For every 1mL=1cm³ so there we had the volume found with the graduated cylinder. We divided the mass by the volume in order to get the density Data: We found that the density of our unknown was 0.76 g/cm3.
Lab report Experiment 6 The synthesis of Alum Lingrui Ge Oct 18th 2015 Purpose: discover the synthesis of alum. Materials: two 250 mL beakers, 400 mL beaker, 25 mL or 50 Ml GRADUATED cylinder, Buchner funnel and filter flask, watch glass, glass stirring rod, lab burner, ring stand, ring, wire gauze, hot plate, wash acetone, Aluminum foil, 3 M sulfuric acid solution, KOH, 50% enamel solution, ice bath, balance, boiling chips, gloves, pipe cleaner. Process: get and wear goggles, set up a Buchner funnel and flask and measure its mass.
We calculated the density of the metal ball to be 7.83 g/cm3 using methods IV and V and concluded it was iron. C. The density of the plate was calculated to be 2.667 g/cm3 using methods IV and V. Thus we concluded that it was aluminum. 3.
Next, I removed the water and the quarter from the graduated cylinder and poured 50 mL of water again. I repeated this until I got results for all three coins. To find the volume of each coin, the formula I used was volume of water and coin - initial volume of water ( 50 mL ). To find the density, I divided the mass and the volume of each
AP Chemistry enthralled me with its indecipherable French theories and alphabet of Greek formulae, for my studies transmuted these into poignant prose. Information that had once seemed impossibly complex soon flowed from my mind as effortlessly as a pleasant conversation with a friend, and I began tirelessly consuming the material as though I had been starving for it. Cravings which had been subconsciously growing in me since childhood were relieved with a feast of answers: The fundamental concepts of existence revealed in a humble high school classroom. Soon, the only thing more insatiable than my curiosity was my ambition to apply this newly-acquired knowledge to the aching problems of the world. Studying the very building blocks of the universe
A foil is most commonly defined as a character who contrasts with another character. Foils are all around you, yet they usually go unnoticed. The Wicked Witch and Glinda the Good Witch. Peter Pan and Captain Hook. Shrek and Donkey.
= 10^-3 M = 1,000 mL Here C1,C2; are the first and second concentrations of solution V1 and V2 ; are the required and current volumes. The impeller turned on and DDA, and tap water left to be mixed properly with water for 2 minutes. Approximately 150 grams of quartz added into the solution.
In the Penny Boat Lab, we made a boat to hold pennies in water. First, we collected materials we needed which were scissors, a ruler, water, pennies, aluminum foil, a triple beam balance and a container. Using the ruler, we measured the foil 15cm by 15cm, then cut excess pieces. Next, we had to fold the foil into a “boat”. After, we measured the mass of our boat using the triple beam balance.
Each group was assigned a different percent of sucrose solution out of the four variables; 0% , 5%, 10%, and 15%. After we filled the beaker we then got two potato cores. Once we had the cores we cut the skin off the ends. Following this we then cut the two potato cores into four 2.00 cm potato cores. After they were cut into 2.00 cm each we found the mass.
5. Join the side arm flask to source of vacuum. While dealing with this experiment you should always use thick walled tubing, the pressure will collapse with the Tygon tubing. 6. Wet the filter paper with a tiny amount of solvent to be used in the filtration.
1.Introduction Stainless steels are engineering materials and it are a complex group of iron based alloys containing at least10.5% chromium and a maximum of 1.2 % carbon. In order to define the stainless steel it can be said that the base alloy for this material is iron which contains a minimum of %11 Chromium (Cr) [1]. The European Standard EN10088 (EN2005) defines stainless steels as iron based alloys containing at least10.5% chromium and a maximum of 1.2% carbon. The main factor for the corrosion resistance of stainless steel is its chromium content. Under the influence of oxygen from air or water, the chromium rapidly forms a very thin, chromium (III) rich oxide film on the surface of the steel.
