1-38. To entertain children between the ages of 2 and 90, I enjoy popping corks from bottles containing vinegar and baking soda pour about 50 mL of vinegar into a 500-mL plastic bottle. Then I wrap about 5 g of baking soda (which is sodium bicarbonate, NaHCO3) in one layer of tissue and drop the tissue into the bottle I place a cork tightly in the mouth of the bottle and step back. The chemical reaction generates CO2(g) that pressurizes the bottle and eventually bursts the cork into the air. Everyone smiles. I CH2CO2HNaHCO3 >CH2CO2 + Na + CO2(g) H2O Acetic acid Sodium bicarbonate in vinegar in baking soda (a) Find the formula mass of acetic acid and of sodium bicarbonate (b) How many grams of acetic acid are required to react with 5 g of NaHCO3? (c) Vinegar contains ~5 wt% acetic acid. How many grams of vinegar are required to react with 5 g of NaHCO3? The density of vinegar is close to 1.0 g/mL. How many mL of vinegar are required to react with 5 g of NaHCO3? (d) Which is the limiting…

(a) Is it true that 26.3 mpg gasoline translates to 319 g CO:/mi? i. Convert mpg (miles per gallon) to miles per kg (of gasoline) using the density of gasoline ii. Convert kg of gasoline to kg of C assuming the overall formula for gasoline is CıH1a5 ii. Convert kg of C to kg of CO2 iv. Now finally compute g CO:/mi corresponding to 26.3 mpg and compare to 319 g CO2/mi

The mystery fuel speedster! (Homework ) For fun, you build an explosive car with your little brother by attaching wheels to an empty windshield washer container. To advance it, you add 1.20 ml (  = 0.7915 g/ml) of a liquid but volatile fuel into the container. You close the cap and shake to evaporate the liquid. Finally, you place the car on its wheels, remove the cap and insert a burning wooden rod into the container. A flame suddenly comes out of the car, which is propelled with good speed in front of your little brother surprised, but all upset by the maneuver.   The volatile fuel is composed of 37.5% carbon, 12.6% hydrogen and 49.9% oxygen. Its molar mass is approximately 32.0 g/mol.   During the reaction, the fuel (gaseous) burns in the presence of gaseous oxygen, and the products of the reaction are carbon dioxide and water, gaseous too. The volume of the windshield washer container used is 4.00 litres. Useful Info: There is 21.0% gaseous oxygen in the air and initial conditions…
