Baby Bottle Lab

This past week in class we did a lab using baby bottles. This was a really fun lab. We had to create a formula with baking soda and vinegar to shoot a baby bottle 600cm. The formula looked a little something like this, NaHCO3 + CH3COOH --> H2O + CO2. We had to figure out the best amount of vinegar to use with a certain amount of baking soda so there would be no excess vinegar. Here's an example, if you had 8g of baking soda, you would use this calculation: 8gNaHCO3/1*1molNaHCO3/84gNaHCO3*1molCH3COOH/1molNaHCO3*
60gCH3COOH/1molCH3COOH*100gvinegar/5gace acid
This would give you 114.29g of vinegar. I tried this many times with with different amounts of baking soda. My trial runs were making it to 550cm and 600cm, until the top of my lid blew off on one of the trial runs. So, then i had to use a new bottle with new amounts, but i was still able to reach 550cm. I believe this lab was the funniest I've done so far.
