Aim To find out the difference of reaction time it takes for the baking soda when it meets the vinegar under the condition that the volume of the vinegar changes. Background Information The two reactants‚ which are baking soda and vinegar‚ react with each other. Then it creates product‚ carbon dioxide‚ water and sodium acetate. The chemical name of vinegar is ethanoic acid and baking soda is sodium hydrogen carbonate. To illustrate this phenomenon as a chemical equation‚ it can be shown as C_2 H_4

My hypothesis is that the eggs will absorb the contents it’s placed in and will become heavier. First‚ the fresh hen’s eggs were placed in vinegar. On March 10th‚ 12 eggs were placed

The shell project Our teacher gave the class a project that was about shells and burning them with vinegar. All of us started to put the shells in the vinegar in Tuesday. Then we waited till Thursday the 3rd shell in my teams cup was already dissolving. After seeing on what happened to the shells being in the vinegar for a few days me and my team worked on the weight the shells were. We did graphs‚ charts a lot of work and so little time‚ but we kinda almost completed it‚ I mean one of my

We have many questions about this project. I don’t want to spoil it to you right now though. We have three questions we are interested in. Our questions are: Does vinegar temperature affect how fast the volcano erupts? Which ingredient makes the liquid inside

Amanda Anile Course: CHM 101 (E05N)-NVCC Professor: Mihaela Chamberlin Date: 29 April 2017 Experiment Title: Acid-Base Titration Abstract: Vinegar is a common household item containing acetic acid as well as some other chemicals. This experiment is designed to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH. CH3COOH(aq) + NaOH(aq) -> CH3COONa(aq) + H2O(l) By adding the sodium hydroxide‚ which is a basic solution

The town council wants to build a statue that will not be affected by acid rain. In this experiment‚ three different types of rock are used on vinegar (acting as acid rain). The rocks used are marble‚ granite‚ and red sandstone‚ which are the most popular forms of rocks used to build monuments. Each type of rock will be submerged under 20 ml of vinegar in their own separate container. The pH of acid rain around 4.0. Acid rain is caused by a chemical reaction when sulfur dioxide and nitrogen oxide
