Whenever my mom cooks I kinda wonder, why does liquid smell? How do different types of substances (Vinegar, Water, Vegetable oil) affect the outer eggshell? Well, I'm here to put it to the test. As I thought of many liquids my mom cooks with (Water, Vinegar, and Vegetable oil) I started to think of the smell, “huh, why does vinegar smell so sharp?” Well, I then went on the internet and found out that vinegar contains acetic acid which makes vinegar have its strong taste. Then I thought, does this mean it actually doesn't have that much of different chemicals?
In addition, I thought of an egg. Since an egg has an outer shell on it like skin it can be measured by how bad it feels and how much it affects the egg in 1 minute. Then I thought,
...ost likely to be battery acid. If it is water, it has a Ph level of around 7. For vinegar, the Ph level is approximately 2.4 - 3.4. Thus, once testing the liquid compare it with the Ph levels above to discover the mystery solution.
The only materials needed in the experiment were a single dial caliper, and the skin of the participant that was measured (Lab Manual). A dial caliper was available for purchase online through the use of a simple Google search. The dial caliper was a long metal object with one dial, that was adjustable and that moved the two sharp points at the end of the caliper further away from each other. The purpose of the dial caliper was to measure the length of space between the two sharper points of the dial caliper.
... a possession to me, a personal, private possession, as nothing else in my life ever had. Now it ran nowhere but in my head, but there it ran as though immortal. I could feel it. I can feel it in different places on my body.
time. Not just for its special effects, but for the philosophical meaning behind it. To
When the hydrochloric acid was poured into marble chips, gas bubbles were seen – signifying the carbon dioxide (gas) that was being produced due to the chemical reaction.
Going into the egg drop project our group felt confident due to an abundance amount of research each one of us had done. Our cradle consisted of an inner tetrahedron base, using clear straws that were taped together holding the egg inside within the zip lock bag. The outer part of our cradle was formed by a full straw being cut in half then taped side-by-side, increasing the strength of the straws, then tapped at the vertices of our tetrahedron; facing the opposite direction of the egg. Rubber bands were then wrapped around the center of the entire model, further holding the straws in place.
I chose an hourglass for this one, because a hourglass has sand. Every single time a grain of sand falls from the top to the bottom that is a unit of time.
Using the syringe method I am going to investigate the reaction between Marble chips and hydrochloric acid by measuring the volume of carbon dioxide formed. Chemistry Using the syringe method I am going to investigate the reaction between Marble chips and hydrochloric acid by measuring the volume of carbon dioxide formed. This reaction rate will tell me how fast or slow a chemical reaction is and there are four things that could affect this greatly they are- * Concentration-An increase in concentration means there are more particles. More particles mean that there will be more collisions. * Surface area-When one of the reactants is solid; the reaction can only take place at the surface of the solid.
Chemical: Acids in foods and beverages such as citrus fruits, spices, wines and carbonated beverages; acids produced by acidogenic bacteria following carbohydrate exposure; acids from gastric regulation. (Wilkins, BS, RDH, DMD, 2013)
it if only on a purely human level, if one may speak in those terms.'
For example, Febreeze is made of molecules called cyclodextrin. When the product is sprayed, the water typically diffuses the odor on contact. This allows the “donut” shaped molecules to soak up the toxins and bacteria that cause the odor.
Well, commercial cleansing products available in the market are not only costly, but are filled with toxins & chemicals. Regular usage of these chemical products at home can have long-term adverse effects, which may eventually lead to various health problems. This can be avoided by making homemade cleaners with all-natural ingredients like lemon, vinegar, baking soda, salt, olive oil, etc.

What is a detergent some people might ask? Have you ever used something in your kitchen has that some type of good smell. The start of it began in the 1930’s Robert Durcan and protector went to europe to meet with people and see what they had.They learned what they could apply to it and went to work. A detergent is a water soluble cleansing agent that comes together with impurities. Water cannot clean clothes by itself so detergent is used because one end is strongly
