Tartaric acid

The substances found on the victims of the crash can be easily identified through simple math. You start by taking the percent values of each element found in the substance and changing it to grams, where one percent equals one gram, so that each element is out of one hundred grams. After finding the grams, you find out the moles of each element by multiplying the gram amounts by the conversion factor, which is 1 mol over the molar mass of the element you are dealing with, 12.01 grams for carbon…

THEORY An acid is a proton (H+) donor A base is a proton (H+) acceptor EXPLANATION OF THE THEORY: Acids are proton donors and bases are proton acceptors. A hydrogen ion is the same thing as a proton since hydrogen consists of a proton and an electron. When hydrogen loses an electron all that is left is a proton. According to the Brønsted-Lowry theory of acids and bases, when an acid and a base react, a conjugate base and a conjugate acid will be produced. EXP: acid + base à conjugate acid+…

Truth: yes, thick moisturizer is good but a moisturizer must have lactic acid or emollient type properties. You can also use gel based moisturizers as skin can absorb these gel must faster than the normal creamy moisturizer. Baiden Mitten: Myth: Baiden mitten cannot help in dry skin and it is just a normal cosmetic product.…

consists of constant changes between water (H2O) and carbon dioxide (CO2) to form carbonic acid (H2CO3) and, if needed, it will break the weak acid and from bicarbonate (HCO3-) and very little hydrogen ions (H+). This equilibrium allows for the equation to vary back and forth maintaining a constant pH value within the species. For instance, when hydrogen is missing, more water and carbon dioxide will form carbonic acid and will therefore dissociate replacing the missing hydrogen ions and…

Cool Mints When eating a mint a cool sensation bursts through one's mouth, but is that mint really making their mouth cold, or is it just their mind playing tricks on them? This science fair project is questioning whether or not mints really make one's mouth cold. To test this the theory, the project will include a glass of lukewarm with mints added in every few minutes. How will adding mints in a glass of room temperature water affect the temperature of water? Why does it feel like mints cool…

In the experiment, I tested how soapy water would affect the amount of droplets the penny can hold. The results of my experiment show that the penny holds less droplets of soap water. When the soap is added to the water, the soap collides with water breaking down the tension. As a result, it harder for the droplets to hold together. To find whether my hypothesis was right, I did several of trials to figure out whether my hypothesis was correct. The trials were used to show how soap can change…

Minoxidil, an antihypertensive vasodilator medication, which was developed in the 1950’s by a company called Upjohn originally used to treat ulcers. During their experiments with dogs, they figured out that it did not cure ulcers, but acted as a vasodilator. Due to this recent discovery, Upjohn was able to develop a compound called Minoxidil in 1963 as well as being able to synthesize over 200 variations of the compound. The molecular structure and compound of Minoxidil is C9H15N50, made…

innate protein particles or aggregates.However, there is a mechanistic difference between the two aspects. In the case of a pure solubility issue, i.e. a protein becomes insoluble in a certain solution (no changes in protein structure and integrity) and a solid phase is formed, a strong dilution of the system may lead to the dissolution of the protein. In such a circumstance, the term “protein associates” may more appropriately describe the formed protein solid .In this instance, protein…

air to pass through. The semipermeable membrane covering the outer and inner shell membrane has an outermost coating called the cuticle to keep bacteria from entering the pores (Nelson, n.d.). The experiment will be conducted to determine which acid or base corroded most of the eggshell in the given amount of time. There will be a control group placed into water to compare to the variable groups Diet Coke, Red Bull, and lemon juice. The dependent variable is the amount corrosion on the…

light gray color and the strips of zinc added to solution were approximately 5 cm. When zinc was tested with water there were no noticeable characteristics of a reaction occurring, such as bubbling or a color change. When zinc was added to the weak acid H2SO4, at first there was no noticeable reaction, however,…
