7. An oxygen tank in a laboratory has an internal pressure of 12 atm at 25°C. If the pressure inside the tank exceeds 25 atm, the tank will explode. A fire breaks out in the laboratory raising the temperature of the gas cylinder to 398 "C. Show how to determine and then calculate the final internal pressure of the tank and indicate if the tank will explode or is safe may assume that the volume of the tank...
1. If nitrogen gas has a density of 1.14 g/L, and an unknown gas
has a density of 4.2 g/L at the same temperature and pressure, what
is the ratio of the rate of effusion of the known gas to the rate
of effusion of nitrogen?
2. The combustion reaction for octane burning in oxygen is:
2 C8H18 (l) + 25 O2(g)
→ 16 CO2(g) +18 H2O(g)
∆H = -10869 kJ .

1. A rigid (constant volume) tank sealed by a valve initially contains 100 kg of air at a pressure of 100 kPa and 300 K. At time t = 0, the valve for the air tank is opened in a controlled manner and air leaks out isothermally (constant temperature) of the tank at a constant mass flow rate of 1 kg/s. The valve is closed after 75 seconds. Answer the following questions: Assuming air is an ideal gas, what is...

A 38.0 L gas tank at 35 c has nitrogen at a pressure of 4.65 atm. The contents of the tank are transferred without loss to an evacuated 55.0 L tank in a cold room where the temperature is 4 c. What is the pressure in the tank?
A tank contains 17.5 ft^3 of Nitrogen (N2) at -100F and 1370kPa. Using the equation for the ideal gas model, determine the mass of the N2 in kg. pV=mRT where p is the pressure, V is the volume, m is the mass, T is the temperature and, R is the universal gas constant per unit of mass. For N2, R=0.2968 kJ/(kg*K)
