Balloon Blow Up!TaskCreate an experiment whereby you will test and determine which variables allow for the greatest amount of CO2 production.5048250635000IntroductionBaking soda and vinegar react with one another because they both have a lot of energy that they don't want and they can help each other get rid of it! You might think this explanation is too simple, but it's true to what's happening.Before we go into more detail, let's be clear about our materials. The chemical name for baking soda is sodium bicarbonate. Its chemical formula is NaHCO3, meaning it's made of one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms. Vinegar is a mixture of acetic acid and water. Dilute acetic acid is the chemical name for vinegar, and its chemical formula is CH3COOH. From here on out I will write the chemical formulas in parentheses.left74676000Baking soda is a base, and vinegar is an acid. An acid is a chemical that wants to get rid of a proton, or a positively charged hydrogen atom. A base is a chemical that wants a proton. When you mix an acid with a base exciting things can happen because the acid is ready to give away its proton and the base is right there to receive it!Water is often added to acids and bases to tone down the intensity of this exchange. Water also acts as host in which the acid and base can break apart and react. In water, baking soda breaks apart into a positively-charged sodium ion (Na+) and a negatively charged bicarbonate ion (HCO3-). An ion is a charged atom or molecule. Acetic acid doesn't break apart on its own in water as much as sodium bicarbonate; it's mostly diluted so it's not as strong.When we mix baking soda and acetic acid in water together, acetic acid gives its proton to the broken-apart baking soda and together they form sodium acetate (CH3COONa), water (H2O), and carbon dioxide (CO2). These products are created quickly, and the carbon dioxide comes out as a gas, so the whole event is spectacular as you've seen!37814251270000By reacting with each other, the acidic acetic acid and the basic sodium bicarbonate give up a lot of their energy and create things that have a lower energy relative to each other. The universe favors things at their lowest energy, and so we see a lot of exciting reactions involving acids and bases.Variables you are encouraged to think about…Amounts of vinegar and baking sodaTemperature of vinegarDifferent acidSize of test tubeOwn variableTo Complete and Hand In1. Title – be very descriptive2. Problem – what are you trying to determine?3. Hypothesis – an “if…then…because…” statement.4. Materials – list what you used5. Procedure – use a numbered list, use passive past tense6. Observations – Table with collected data. Graph of data. You will need to think about how you are going to collect the data and compare different trials to each other.6. Conclusion – restate hypothesis and indicate whether you were right or wrong7. Discussion – answer questions below, what would you do differently next time?DiscussionWhich part of the lab did you find most challenging? Why?Using chemical equations to describe what is happening in this reaction.What is CO2 and why is it important to our bodies? Why is CO2 important to plants?Identify the connection between plants and animals and CO2?The following graphic has been taken from (). Interpret three different facts from this set of graphs.
