DOES BAKING SODA AND VINEGAR INFLATE A BALLOON?
INTRODUCTION
This experiment is investigating if baking soda and vinegar will inflate a balloon. Baking soda is a chemical salt that occurs in its natural form as the mineral NaHCO2. NaHCO2 is an amphoteric compound, this means that it would react as an acid and a base. Vinegar is a liquid chemical, which consists of mostly acetic acid and water. CO2 is a gas called carbon dioxide. This gas is a natural occurring compound, which consists of a carbon atom covalently double bonded to two oxygen atoms. This reaction of baking soda and vinegar is a chemistry reaction. This is because the two substances of baking soda and vinegar are both chemicals.
AIM
To determine if changes in amounts of baking

In the graph it shows that the bottle with the highest reaction is Experiment number 3 and the lowest reaction was Experiment number 1. The hypothesis and aim are supported by the results because the greater ratio of baking soda and vinegar will create a bigger reaction.

Baking Soda and Vinegar: Limiting Reactant Lab Background The limiting reactant of a chemical reaction is the substance that places an upper bound on the amount of product that the reaction can produce. The limiting reactant places this upper bound because the reaction must stop once all of the limiting reactant is consumed. If the relative amount of reactants is altered, then the limiting reactant may change accordingly.
...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.
Which brand of soda tested spews the most liquid when three Mentos are doped into a 2-liter of each brand? We know that the reaction between Mentos and soda is an explosion, but what we are trying to figure out is which brand causes the biggest reaction.
The article “Chemistry of Winemaking: A unique Lecture Demonstration” by L. B. Church of the State University of New York, seeks to demonstrate how the winemaking process can be used as a teaching tool. Found in the Journal of Chemical Education, the text uses an instructive and formal tone while discussing the process and how it might relate to the classroom. His rhetoric leans heavily toward the use of logic. Aimed at chemistry teachers, the article refrains from using step-by-step demonstrations of each and every process, and instead discusses the use of common techniques that could be used within the framework of winemaking. By guiding the readers through the general process, the author makes it seem logical and easy to implement a demonstration that would capture and maintain the interest of students.
As you may know, when you mix baking soda and vinegar there is a big reaction, but have you ever wondered how this reaction happens? Well in order to find out how it happens you will need to know the elements that make up baking soda and vinegar. You will also learn why these elements are where they are on the periodic table and what is released during the baking soda and vinegar reaction.
When Alka-Seltzer comes in contact with water, a chemical reaction immediately occurs that releases carbon dioxide gas. This reaction creates a lot of bubbles and fizz like a soda, and like a soda, the bubbles are carbon dioxide gas (CO2).
I have been a snob. It is quite soft, but solid. It reacts with hydrochloric acid. like this 2 CaCO3 + 2 HCl â’ CO2 + CaCl2 + H2O. producing carbon dioxide, which is what we measured in the experiment. There are different factors affecting the rate of this reaction, such.
CaCl2 + H2O + CO2
In our Biology Lab we did a laboratory experiment on fermentation, alcohol fermentation to be exact. Alcohol fermentation is a type of fermentation that produces the alcohol ethanol and CO2. In the experiment we estimated the rate of alcohol fermentation by measuring the rate of CO2 production. Both glycolysis and fermentation consist of a series of chemical reactions, each of which is catalyzed by a specific enzyme. Two of the tables substituted some of the solution glucose for two different types of solutions. They are as followed, Table #5 substituted glucose for sucrose and Table #6 substituted the glucose for pH4. The equation for alcohol fermentation consists of 6 Carbons 12 Hydrogens 6 Oxygen to produce 2 pyruvates plus 2 ATP then finally the final reaction will be 2 CO2 plus Ethanol. In the class our controlled numbers were at Table #1; their table had 15 mL Glucose, 10 mL RO water, and 10 mL of yeast which then they placed in an incubator at 37 degrees Celsius. We each then measured our own table’s fermentation flasks every 15 mins for an hour to compare to Table #1’s controlled numbers. At
In this experiment, the calcium carbonate was in the form of marble chips. The calcium carbonate reacted with hydrochloric acid when the acid was poured into marble chips. Due to calcium carbonate’s higher reactivity, it displaced hydrogen in the hydrochloric acid. As a result, products of calcium chloride, carbon dioxide and water were formed. As the chemical reaction occurred, the water in the measuring cylinder was displaced and gas bubbles that were blowing out represented carbon dioxide.
I predicted that gummy bears will grow the most when soaked in Coca Cola. The research shows I was correct. The gummy bear in vinegar grew .3 centimeters, the one in water grew 1 centimeter and the one in Coca Cola grew 1.4 centimeters. The gummy bear in salt water shrunk .5
Carbon Dioxide is a colorless, odorless gas that occurs in small quantities in the earth's atmosphere naturally. The earth's ocean, soil, plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a 'linear molecule'.
The labels have fallen off of two bottles thought to contain solid sodium chloride or solid sodium carbonate. Describe a simple experiment which would allow you to determine which bottle contains which solid.
The formation of an odor is when chemical changes create a smell. For example when something rots it usually smells disgusting. Temperature change happen sometimes because chemical changes are normally accompanied by it. For example if you burn paper it will become much hotter. The formation of bubbles is another sign of chemical change, for example when you mix baking soda and vinegar it creates many bubbles. Finally formation of a solid may form, called precipitate. All in all chemical changes may have occurred if you observe some of these five factors.
The actual, theoretical, and percent yield of sodium chloride was found. Sodium Carbonate was mixed with hydrochloric acid and the liquid was boiled until there was nothing left. The result was the production of salt, or sodium chloride.
