Are naked eggs‚ eggs with no shell? What? You may think I am speaking about a hard boiled egg‚ but‚ no. Boiled eggs have their centers heated making the shell easily come off. Naked eggs have their shells taken off with one simple ingredient everyone has: vinegar. The acetic acid inside the vinegar strips the shell‚ calcium carbonate‚ away from the egg‚ the chemical formula is: CaCO3 (s) + 2 HC2H3O2 (aq)→Ca(C2H3O2)2 (aq) + H2O (l) + CO2 (g) (Imagination Toledo‚ 2017) Once the egg has been separated

a solute such as salt is present in low concentrations to an area in which the solute is present in high concentrations. There are three types of osmosis: hypertonic is when there is high concentration and the cell has no water inside it (shrunk)‚ hypotonic is when there is low concentration and the cell has swelled up or in other words has a lot of water inside it‚ isotonic is when the water comes in and out of the cell and stays the same shape. All the carrots we put in the salt solution was from

Darielle Donato Eric Valerio I. Introduction Salt‚ also known as common salt‚ table salt‚ rock salt‚ or halite‚ is an ionic compound with the formula NaCl (sodium+chloride). Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. Because of its importance to survival‚ salt has often been considered a valuable commodity

How is Vitamin C manufactured? Ascorbic Acid Also known as: l-ascorbic acid‚ vitamin C‚ ascorbate A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets‚ and necessary to maintain connective tissue and bone. Its biologically active form‚ vitamin C‚ functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant. http://pubchem.ncbi.nlm.nih.gov/summary/summary

My hypothesis stated that I believed salts with a larger density will increase the temperature of the ice faster than salts with a smaller density because the heavier salts will sink through the ice faster since they have a heavier density than water and stop the molecules from staying ice faster‚ consequently raising the temperature of the solution‚ than lower density salts would. . The data I collected shows potassium chloride‚ which has a density of 1.98 g/㎤‚ increased the solution’s temperature
