5.25 grams of baking soda (NaHCO3) and excess vinegar were combined (reaction below).NaHCO3 (s) + CH3COOH (aq) NaCH3COO (aq) + H2O (l) + CO2(g) a.How many moles of CO2gas areproduced? Hint: use mole ratio.   b.Whatvolume of CO2gas is produced when the reaction takes place at1.12 atm, 22.85 °C?   c.Instead of doing this reaction in an air-conditioned classroom, the same reaction is performed outside on a hot Indiana summer day at 32.22 °C. Will the volume of CO2gas produced increase, decrease, or stay the same?Explain your choice.

When ammonium nitrite is heated, it decomposes to give nitrogen gas and water. This property is used to inflate some tennis balls. Write a balanced chemical equation for this reaction. Calculate the quantity (in g) of ammonium nitrite needed to inflate a tennis ball to a volume of 86.2 mL at 1.20 atm and 22 ˚C.

The average kinetic energy of the molecules in a gas sample depends only on the temperature, ?. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed   rms speed=3??ℳ⎯⎯⎯⎯⎯⎯⎯⎯⎯√rms speed=3RTℳ   where ?=8.314 J/(mol⋅K) and ℳ is molar mass in kilograms per mole. Note that a joule is the same as a kilogram‑meter squared per second squared (kg·m2/s2). What is the rms speed of F2 molecules at 319 K? rms speed:________________________________________________________m/s   What is the rms speed of He atoms at 319K?   rms speed:________________________________________________________m/s
