there. The volume of liquid in the beaker before the egg was placed in was 150 mL, and when the egg was taken out, the volume decreased to 130 mL. This proves that some of the distilled water that was in the beaker passed through the cell membrane and into the egg, which explains why the mass of the mass increased, while the volume of water decreased. The distilled water didn’t have any minerals or gunk that prevented it from going through the cell membrane easily, while the liquid that was in…
like dust particles or a feather. Part B, we used onions, blue methylene and water. It's called a “Wet Mount” since we used a liquid substance (blue methylene and water).Wet mounts are used with a piece glass concave slide and a solid object for viewing it. A drop of water or other liquid substances is dropped onto the object and a cover slip is slid on top of the liquid. The tension of the surface of the water automatically will close the cover tight to the slide while still holding the object…
in such a manner that prevented emerged bubbles that could have formed disrupting test accuracy. o Temperature of the liquid was collected once the fluid was in the cylinder. 3. Dropped into the cylinder was a Glass (Dark) ball then a Steel (Silver) ball twice for a total of four trials. o Each ball was fished out smoothly from the oil to be removed with a hook utensil. o The liquid was drained out about halfway back into the measuring cup at a slightly incline manner pouring slowly. 4. Slow…
of 3M HCl was added and swirled into the solution. The top of the 25-mL flask was capped and the two liquid were mixed in a thorough manner. Ventilation was required after every few seconds. After letting the solution sit for a while and letting the liquid layers separate,…
collected shows that my hypothesis was correct because the average number of the different amounts of salt was higher than the last one. Water boils when the molecules are able to overcome the vapor pressure of the surrounding air to move from the liquid phase to the gas phase. With that being said when you add salt that increase the amount of heat needed for water to make the transition( chemistryabouteducation). The more salt you add to water, the more you raise the boiling point. For control…
Observations or reactions: Separation of the basic component: When 2ml of 3M HCl was added to the mixture of Benzoic acid, Ethyl 4-aminobenzoate, 9-Fluorenone, diethyl ether, two layers were created, an organic yellow top layer and a clear aqueous bottom layer. The clear layer (basic layer) was extracted and placed into a container where 6M NaOH was add to the solution. The addition of NaOH made the solution basic, and created white flakes in the solution. The white flakes were separated by…
think that this means for crystallizations in general (since ice is crystallized water)? Crystallization is the physical transformation of substances like liquid, therefore, the water undergoes a physical transformation from water to crystallized water. These two are both the same substance; they are just in a different physical state (liquid to solid). Furthermore, this proves crystallization occurs as substances change from one state to another. Did you observe about how much of the ice…
Paintball is a game that shoots out markers or paintballs, that when they hit, the markers explode causing a paint mark on a person, a piece of cover, and trees.Paintball is also a game where many people do different types of games like capture the flag to different battle scenarios. Before paintball was a game paintballs was used to mark cattle for shipping purposes. Many people play this game with pump guns. These guns have an air pump attached and also a hopper.The hopper is the top piece of…
The optimum dental treatment for any patient is to restore teeth function and esthetic while removing the least amount of tooth structure, and replacing it with a dental material that will be biocompatible with the tooth and resist the hostile oral environment. Dental materials are incorporated into the teeth structure by retention. This retention can accomplished through mechanical, chemical adhesion or bonding mechanisms between materials and the dental structure. Mechanical retention is…
Fracking has large impact on daily life for global consumers, it effects prices and availability of fuels for consumers. Fracking is an exceptionally complicated process. To start the process, a ten thousand foot well is drilled below the surface into shale layers. Next, 1 to 8 million gallons of water mixed with chemicals are injected into the well at extremely high pressures to crack the rock. This will allow the product to flow out once the water is mostly removed. This process is highly…
