Procedure [C, 8] Part A: Iron (III) Nitrate and Sodium Hydroxide 1. Sliding the mini test tube into the empty Erlenmeyer flask and sealing it with the rubber stopper were practiced a few times before conducting the experiment. 2. 5 ml of Sodium Hydroxide solution was measured using the graduated cylinder. After, it was poured into the empty Erlenmeyer Flask. 3. 3 ml of Iron(III) Nitrate was poured into the mini test tube. Next, the Erlenmeyer Flask was tilted and the mini test tube

The Ancient Egyptians used thymol and carvacrol as protective drug agents to protect preserve of the mummies(15). Thymol are known to destroyed microorganisms due to presence of these compounds(16). In Ancient Greece thymolthyme was employed as improving flavor additive(17). ThymolThyme is also used as antiseptic agent in mouth washes, and sore throats (17).

The difference between this salt and the others is that it contains pure mineral compounds of sulfate

Research – Water Patterns Firstly, I extracted frames from a video I shot of water droplets falling from a syringe into a pink tub. I found the contrast unsatisfactory, so I converted the image to greyscale and increased the contrast by a large amount. Next, I selected the image I felt looked the most attractive and cropped it for testing different mediums. I wanted to investigate ripple patterns, so I coded a program in Scratch to create ripple patterns. It worked well at first, but then as the

Does pollution actually affect the pH levels of water? And if so, does it make the pH level higher? Our experiment will test the hypothesis that the more polluted water is, the higher it’s pH level. We collected four samples of water from four separate locations to test its pH level based on a pollution scale we have created. On the pollution scale, 0 is clear, 1 is clear with specks of dirt, 2 is murky, 3 is a greenish tint, and 4 is brown with dirt. We will test each water sample and find it’s

Experiment 7 “Carbohydrates” and the purpose for this lab is to become familiar with the properties of different classes of carbohydrates. Test such properties of carbohydrates as solubility, reduction, and hydrolysis. To do part A (solubility), begin by adding 10 mls of distilled water to three test tubes and add 2 grams of starch to one tube, 2 grams of glucose to the second, and 2 grams of sucrose to the third test tube. Shake it well and record it on the data sheet. Part B (benedict’s test),

Blood is always red, even though veins appear blue through skin. Kienle Et Al published an article over twelve years ago in the journal Applied Optics and entitled “Why do veins appear blue? A new look at an old question”. Based on the findings of the authors, three reasons are explained as to why veins appear blue. The first two are directly from the way in which light interacts with blood. The third is psychological, dealing with color perception. Not only is blood not blue, veins themselves aren’t

for or against your hypothesis? This is not evidence that goes against my hypothesis.But yes, those tasting PTC can taste thiourea because everyone I reviewed says they can taste theoria , and they said this after they tasted the chemical.Two if the people said thiourea taste like PTC but stronger. In general, could those tasting PTC also taste sodium benzoate? Is this evidence for or against your hypothesis? This evidence is goes with my hypothesis,those tasting PTC can somewhat taste sodium

Diet Coke and Mentos Final Experiment Directions: Design your own experiment to test some variable of the Diet Coke and Mentos lab. Identify one variable that you will change and test – this will be your Independent Variable. Independent Variable: ____Amount Of Mentos__________________________________ Dependent Variable: __________________Geyser Height (feet)____________________ Problem: How is the height of the geyser affected by the number of mentos added to the Coke? Hypothesis (Use
