3. A helium filled balloon has a volume of 39.0mL at 17C and the current atmospheric pressure is reading 802mmHg on the barometer. What volume will the helium gas take up when the pressure reading on the barometer drops to 637mmHg and the temperature plummets to 7C?
Answers: 1
x 
= .039 L
x 
= 1.055 atm
= .0017 number of moles
= .0466 L of helium, or 46.6ml Less pressure means it will take up more space.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
