Three bulbs are connected by tubing, and the tubing is evacuated. The volume of the tubing is 50.0 mL. The first bulb has a volume of 88.0 mL and contains 4.63 atm of argon, the second bulb has a volume of 250 mL and contains 1.69 atm of neon, and the third bulb has a volume of 30.0 mL and contains 4.96 atm of hydrogen. If the stopcocks (valves) that isolate all three bulbs are opened, what is the final pressure of the whole system in atm?
Calculate ΔH and ΔStotal when two iron blocks each with mass of 1.00kg, one at 25'C and one at 250'C are placed in contact with each other in an isolated container.
The volume of a sample of gas, initially at 25oC, increase from 158 ml to 450 ml. What is the final temperature (C) if the pressure in the container is kept constant.
if 836.8 Joules are added to 25 grams ammonia at 37 degrees Celsius, what will the final temperature be?
We find coesite and stishovite in shocked Coconino Sandstone at meteor Crater. We infer that coesite and stishovite formed from the transformation of quartz at high pressure and temperature.
Determine the numbers of moles of iron that would be formed from 6.2 moles of CO (carbon monoxide) combining with excess of iron (III) oxide (Fe2O 3 )?
A sample of glucose, C6H12O6, contains 1.265 x 1021 carbon atoms. (a) How many atoms of hydrogen does it contain?
what is the concentration of a nitric acid solution if a 10.00ml sample of the acid reqires 31.25ml of 0.135m koh for neutralization.
What is the value of the equilibrium constant at this temperature for the reaction of SO2 with N2O to form SO3 and N2 (balanced with lowest whole-number coefficients)?
The mass of a cube of iron is 324 g. Iron has a density of 7.87 g/cm3. What is the mass of a cube of lead that has the same dimensions?
A sample containing 4.80 g of gas has a volume of 15.0 L. Pressure and temperature remain constant. What is the new voume if 0.500 mole gas is added?
An expanding gas does 150.0 J of work on its surroundings at a constant pressure of 1.01 atm. If the gas initially occupied 68.0 mL, what is the final volume of the gas.
What would be the value of the change in concentration of C10H12/change in time during the same period of time? Explain why a catalyst for a forward reaction must also be a catalyst for the reverse reaction. Include an energy level diagram
