Purpose The purpose of this lab was to see how an egg would react through a chemical reaction if it were to be added with an acid and a base. II. Materials 1 egg 400 mL beaker Citric acid Baking Soda Water Food coloring (optional) Stirring rod III. Procedure 1. Crack open and separate egg by pouring yolk back and forth between egg shell halves with the whites in the beaker 2. Add 5.0 grams (1 tsp) of citric acid 3. Add 5.0 grams ( 1 tsp) of baking soda 4. Put 2-3 drops of food coloring

Incredible Egg Procedure: On October 5‚ I gathered a large Styrofoam cup‚ an egg‚ some vinegar‚ some corn syrup‚ and some water. Before I started the lab‚ I weighed the egg on a scale. Because the egg would just roll off the scale if I set it down by itself‚ I weighed the cup‚ and then added the egg. After I knew how much the egg weighed‚ I poured enough vinegar in the cup to submerge the egg. I then covered the top of the cup with plastic wrap and set the egg aside. The next day‚ I washed the egg and

will start seeing quite a few sales on eggs. Why? Eggs are one of the main staples in the Easter holiday tradition. Everyone gets together the night before Easter and colors their eggs a wide range of colors to put in their Easter baskets for the Easter Bunny to hide. An egg seems like such a simple food item‚ very few people ever wonder what all had to happen in order for them to be able to buy their eggs from the grocery store. If there were suddenly no eggs to color for Easter I am sure everyone

is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in one-hundred-percent water was that it was
Premium Chemistry Osmosis
Objective: To observe the effects of osmosis on eggs placed in vinegar (5% acetic acid)‚ syrup (60% sugar solution)‚ and water (100% distilled). Hypothesis: Hypothesis #1: It was hypothesised that the egg would gain 59 grams of mass after soaking in vinegar for 24 hours. Hypothesis #2: It was hypothesised that the egg would become larger when soaked in syrup than it once was due to the hypotonic environment. Hypothesis #3: It was hypothesised that the egg would soak in water for 72 hours‚ losing mass

02.02 Early Cells 1. How are cells affected by the movement of water? Cells are affected by the water through diffusion. You see if you when you apply or remove water from the cell it will most likely show you how it functions. For example when you have the egg and you apply a bit of water it will most likely shrink if you add a lot of water it’s mostly likely that the egg will burst. Hypothesis (What do you think will happen to the egg after the three days? Be sure to give a reason for

Egg drop projects teach students to use logic and teamwork to protect their eggs from a fall. There are a variety of ways to conduct an egg drop. Begin by explaining the process and handing out eggs to the students. Set the parameters of your egg drop and a deadline when your students must be ready to drop their eggs or go bust.1.Get an egg-eating snake‚ give it the egg and wait until the egg is about half way down the snake‚ then fit the snake with tail flights (cf a dart)‚ then drop said snake

Egg Lab Report Introduction: An egg is a model of a human because the egg has a cell membrane like humans do inside and outside of the body that let things pass through like water. We can use eggs to study the effect of changes in the external environment on the internal environment by having harsh environments like putting the egg in only alcohol and see what happens to the inside of the egg. Diffusion is the movement of a substance down its concentration gradient from a more to a less concentrated

1.Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane. 2. Explain your observations in detail in terms of concentration gradient‚ diffusion‚ osmosis‚ osmotic pressure‚ passive transport‚ and active transport. Explain what happened to the blood cells at the various levels of concentration. Be sure to refer to the solutions as being hypotonic‚ hypertonic and isotonic. The plasma membranes are made up of proteins that form
