Question

Previous sheet I posted for Lewis structure of SeF4 Does this molecule obey the octet rule? In this molecule polar? Explain Use the ideal gas equation to answer the following questions: If the initial pressure is 2.00 atm and initial volume is 5.00 L, Calculate the final pressure if the volume is increased to 8.00 L A tire is inflated to a total pressure of 2.18 atm at a temperature of 30.00 degree C. What is tire pressure (in atm) if the temperature drops to -1200 degree c? Assuming that the tire pressure warning light comes on at 29 psi, is this reduction in pressure enough to trigger the warning light? Gas constant R = 0.08206 L middot atm/mol k; 14.70 psi = 1 atm

Explanation / Answer

Q3.

initia P = 2 atm, Vinitial = 5 L

P2 = ? V = 8 L

apply ideal gas law ratios

P1V1 = P2V2

2*5 = 8 *P2

P2 = 10/8 = 1.25 atm

b)

tire pressure if T = -12°C = 261

P1/T1 = P2/T2

2.18/(30+273) = P/(261)

P = 2.18/(30+273) *261

P = 1.8778 atm

ii)=

P = 29 psi assume this is abs

so..

P = 1.8778 atm

P = 1.8778 atm --> 27.603 psi

this will turn on the light
