Molecular diffusion

In this experiment I attempted to created and study the affects of a egg in a hypertonic and hypotonic solution. To conduct this experiment I used the following materials: cups, eggs, vinegar, corn syrup, spoons and food coloring. To begin the experiment I placed three eggs in vinegar to dissolve their shells, leaving behind a thin membrane that allowed water to pass in and out of the eggs. The water molecules enter inside the eggs and the eggs begins to swell. Once the eggs have sat in the…

view the effects of an egg in a hypertonic state, hypotonic state, isotonic state and diffusion. Hypertonic is the movement of water leaving the egg to an area of higher concentration. When this occurs the egg becomes shriveled. Hypotonic is the process of water moving into the egg from the outside; the egg becomes swollen. Isotonic is when the water concentration is the same inside as is it on the outside. Diffusion is the movement of solute, a substance, from a high concentration to an area…

6/ Since this is a furnace means that it will always at high temperature so it would be inefficient to just using the sources at solid because it took time to sublime that solid and turn it into gaseous state for diffusion sources. The best efficient way is to use a gaseous diffusions sources. We got 2 candidates PH3 and POCl3. PH3 has a little quirk that escaping gas cannot be extinguished and exposure to fire may cause containers to rupture. This is a high temperature furnace which we will…

cup. This proves that the process of osmosis has happened. Conclusion: In conclusion different concentrations of saline solutions do affect the mass of the baggies due to the effect of osmosis. This also means that what has happened is is the diffusion of molecules from a lower concentration, to a solution of higher concentration. The lower concentration being the baggies. The higher concentration solution being the physiology human solution. Therefore, the research question presented on this…

The essay is divided into four sections, separated by whitespace. What do each of the sections accomplish? The four sections are each divided based on how to dumpster dive. The author wants the reader to know how he dumpster dives and informs the reader on how to do so. In the first section he claims that when you first begin scavenging, you are filled with disgust and self loathing. In the second section he lets the reader know many people think of it as an art and the objects they find. In…

Our goal of the dialysis experiment was firstly, to answer the question of why the dialysis cells appeared smaller after adding sugar water and secondly, to prove our hypothesis that water molecules move out of the cell because the concentration of water is greater than inside the cell than it is outside the cell. This experiment was conducted with one control group and one experimental group. The independent variable was the concentration of water, (water and glucose solution). The dependent…

Eggsperiment Purpose Is an egg similar to a human cell? Hypothesis If the egg is put in milk, then the shell will grow back. According to Mama Natural, “High-quality eggshells contain 27 essential microelements but they’re mostly composed of calcium carbonate, a form and structure that’s very similar to our bones and teeth.” Also, according to My Plastic Free Life, “eggshell powder contains roughly 400 milligrams of calcium per gram.” Since the milk I use, 2% Fat, has 295 milligrams in one cup…

I. Introduction: Osmosis is a mode of passive transport used by the cells. It involves the transport of a solvent like water across a semi-permeable membrane. Osmosis is the movement of solvent molecules from an area of low solute to an area of high solute. In osmosis, the semi-permeable membrane (the lipid bilayer) enables the solvent molecules to pass freely between but limits movements of the solute. Osmosis is the primary way water moves into and out of all cells. In this experiment, the…

Hypothesis: Throughout my observations and my education of the process of Osmosis, the movement of the solutions moving up from the “mysterious” solution inside the semi permeable membrane which is known as the dialysis bag. Osmosis happens because of the molecules crossing, for more of an understanding according to Anita H, she says “…high water concentration to an area of low water concentration through a partially selectively permeable membrane” (Anita) The molecules cross from less…

Active and passive transport move oxygen, water, and nutrients into cells and remove waste. Active transport requires a chemical energy because it moves from lower concentration to areas of higher concentration. It uses ATP to pump the molecules against the concentration, which requires cellular of solute. Passive transport moves from areas at a higher concentration to low concentrations, so it doesn’t require energy. Active transport takes place in the membranes of both the mitochondria and…
