Here are some pictures of us conducting the experiment:
Analysis Questions
1. What are the limiting and excess reagents for each flask?
The excess reagent was the baking soda and the excess reagent was the vinegar. We were able to conclude this by noticing that there was vinegar left over but all of the baking soda had been used up in the reaction.
2. How is the amount of product in a reaction affected by an insufficient quantity of any of the
reactants (reagents)?According to the law of conservation of mass, there will always be the same amount matter on the reactants side as the products side. Because of this when there is less reactants the out come will be less as well.
3. Which balloon was the largest? Explain.
The green balloon was the largest because that was the flask we put the most baking soda into (4 g). With the vinegar this caused the largest reaction. The reactants where large so the products where as well.
4. Which balloon was the smallest? Explain.
The smallest balloon was blue because it had the least amount of baking soda go into it (1 g). There was an excess of vinegar. Because the reactants were small the products where also small.
5. Rust is produced when iron reacts with oxygen. How many grams of Fe2O3 are produced when 12.0 g of iron rusts?4Fe(s) + 3O2(g) → 2Fe2O3(s)
81.6 grams are produced.
6. What real-life applications can this concept of limiting and excess reagents be applied to?
This idea can be applied to making sandwiches. For instance, if you need 1 meat and two bread in order to make one sandwich and you had 100 bread but only 5 meat, then you can only make 5 sandwiches even though you will have a lot of bread left over.
