What will happen when you put a drop of water on wax paper? I think that it will just sit there and do nothing. First I put a drop of water on the paper Second I watched it to see what it will do Finally I wrote down that it just stayed still My hypothesis is correct What will happen when you move the water around with a toothpick? I think it will go flat and dissolve in the in the wax paper. First I picked up the toothpick Second I moved the water around with the toothpick Finally

7 February 20th 2012 Soda Is Bad For You According to statistics‚ in the past couple year’s soft drinks have become much more consumed by Americans. Although most people enjoy the taste of these sugary drinks most research shows that they are bad for you. Drinking soda can cause the enamel on your teeth to dissolve‚ take calcium out of your bones and cause them to weaken‚ cause a person to become overweight possibly obese‚ and cause acne breakouts. Whether you call it soda‚ pop‚ a tonic‚ coke‚ or

The Decomposition of Baking Soda Purpose: - To determine the correct balanced equation for the decomposition of baking soda using % yield. PreLab Notes: Sodium Bicarbonate (Baking Soda) decomposes when heated yielding both gaseous products and solid products. The production of gas makes baking soda a leavening agent in baked goods. The trapped bubbles of gas give muffins and cakes a lighter‚ airier texture. When heated‚ baking soda decomposes in one of the following unbalanced equations.

of Vitamin C contained. The concentration of Vitamin C contained of these fruit juices were identified by using titration. Based on the results‚ the concentration of Vitamin C contained in these 3 fruit juices were obtained. The conclusion of the experiment is that different fruit juices contain different concentration of Vitamin C which is important in our daily lives. CHAPTER 1 1.0 INTRODUCTION 1.1 THEORY/LITERATURE Vitamin C is an essential nutrient in humans as it functions as a cofactor in several

The titration experiments between the three different brands and under the five different conditions showed varied results. As shown in Graph 1‚ the condition which tested most effervescent was when the soda water was under cold temperatures and the least effervescent temperature was when the soda water was warm. When left standing without the lid‚ the soda water proved to be least effervescent. As seen in the above graph‚ under cold temperatures‚ ‘Schweppes’ demonstrated that it was the most effervescent

cheap. Baking soda is simply sodium bicarbonate‚ a substance found naturally in mineral deposits‚ oceans and lake sediments as trona ore. Sodium bicarbonate is also manufactured in the human body‚ where it helps to maintain the correct pH of the blood stream‚ neutralizes stomach acids and plaque acids‚ and carries carbon dioxide from bodily tissue to the lungs. Baking soda is a white crystalline powder (NaHCO3) better known to chemists as sodium bicarbonate‚ bicarbonate of soda‚ sodium hydrogen

When you mix vinegar and baking soda you get a chemical change. The chemical property that causes this is called reactivity. Baking soda’s chemical formula is NaHCO3 and it’s a compound. Vinegar’s chemical formula is CH3COOH and it’s a compound. The problem of this is how much baking soda‚ added to 10mL of vinegar‚ will cause a film canister rocket to shoot the furthest. I think 5mL will shoot the farthest because there will be more for the baking soda build up in the canister. The independent variable
