To calculate the experimental mass the substance of each bag and the bag its self was measured using a balance. After gathering the mass subtract the mass of the empty bag to the mass of the unknown substance, in order to just have the mass of the substance. Afterward the mass of the unknown substance was divided by the number of moles recorded on the bag of the substance. The measurements are displayed on the table
Conclusion: Compare Trial 1 and Trial 2. The Trial 1 change in mass are 12.5g, however Trial 2 changes in mass is 1.2g. The Trial 1 change in mass is more than Trial 2. And I think the Low of Conservation of Mass violated in the Trial 1 is can be exist. Because the Trial 1 actually the soda with vinegar have Chemical reactions occur and chemical
The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.
This experiment is called jumping Pop Rocks. You first fill a glass with water that is 140 degrees fahrenheit. Then you pour the Pop Rocks into the glass. Since the Pop Rocks are infused with carbon dioxide they will tend to jump at the bottom of the glass, or maybe even reach the top of the glass once they dissolve.
We are doing a gummy bear lab. Gummy bears come in different sizes, shapes, and colors. Gummy bears are squishy, chewy, and sticky, they are made of sugar which are glucose and glucose are carbohydrate. We predict that during this stage of lab the solute and solvent will go through the stages of hypertonic, hypotonic and isotonic. We get 4 gummy bears and 4 cups filled half way with different types of liquid, such as Salt-Water, Coffee-Creamer, Vinegar, and Soda.
The mass we measured after the whole process came up, was 121.80g. The chemical reaction happened between the water and the tablet conserves the mass of the water. As a whole point, we claimed that there was a chemical reaction between the water and the tablet that produced carbon dioxide and the mass remained as same as before and after the
Smiley, Gregory College Algebra- Math 1111- SO Evaluate the difference quotient f(x+h)-f(x)/h So this equation is probably going to be in an calculus class also I have yet to take it yet, but I do understand this is in college algebra for which I have taken it.
In our mini-lab yesterday, we put sugar cubes in a jar and shook them for three minutes. The first jar had one cube, the second had two cubes, and the third had three cubes. We were trying to find the impact of the shaking on the sugar cubes. Our sugar cubes represented the rocks, and the shaking was an outside force. My group’s hypothesis was that the sugar cubes would break up.
Senses: How we Identify Different Flavors of Food Aim: To be able to identify the five different fruit flavors of skittles by using the sense of taste, while the participants of this experiment are blindfolded. Research Question: How are we able to identify the five different fruit flavors of skittles (strawberry, orange, grape, lime, and lemon) by only using our sense of taste? Hypothesis: I believe that the blind fold will make it harder for the participants to determine what fruit flavored skittle they have just ingested. This may also alter their perception of taste.
Introduction: Enzymes are needed for survival in any living system and they control cellular reactions. Enzymes speed up chemical reactions by lowering the energy needed for molecules to begin reacting with each other. They do this by forming an enzyme-substrate complex that reduces energy that is required for a specific reaction to occur. Enzymes determine their functions by their shape and structure. Enzymes are made of amino acids, it 's made of anywhere from a hundred to a million amino acids, each they are bonded to other chemical bonds.
Lab Group: Thomas Echelberger, Austin Brown, Erik Holden, and Josh Peeples Introduction: For this lab we had to construct a projectiles launcher that would shoot ping pong balls at different distances. At the beginning of the project we though of doing a generic catapult made of popsicle sticks. But we wanted to go above and beyond. So we decided to make a launcher that would use air pressure to power the ping pong ball.
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.
Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with
How does the amount of baking soda mixed with vinegar affect the volume of gas produced? The rate of reaction is the increase or decrease time taken at which the products are formed or concentration increase or decrease between a reaction of two or more substances. In the reaction, new bonds are formed whilst others have been broken.
1.0 Introduction The name of the business that we investigate is Sugarbun. This business provides the consumer the fast food and delivery services. The food provided are vary from sandwiches to broasted chicken to Eastern Cuisine such as nasi lemak classic, sambal eco fish, chicken curry and else and also varieties of beverages.
