In summary, 1 gram of C3H8 gas and 1 gram of O2 gas are reacted in a 1 L metal sphere, resulting in the formation of 3 moles of CO2 gas and 4 moles of H2O gas. The sphere is held at 226.25 oC after the reaction. To find the final pressure in the sphere, the limiting reagent must be determined, the total moles of gas in the sphere must be found, and the ideal gas law must be used.

1. 1 gram of C3H8 gas and 1 gram of O2 gas are delivered to a metal sphere with a fixed volume of 1 L. After the two gases are introduced, the two reactants are ignited and burned according to the balanced reaction: C3H8(g) + 5O2(g) 3CO2(g) + 4H2O(g)
After reaction, the sphere is held at 226.25 oC. What is the final pressure in the sphere given that all the compounds inside are gases and the limiting reagent is completely consumed with 100% yield ?

1. Determine limiting reagent. Use the equation to find how much product there is and how much excess reagent.
2. Determine the total moles of gas, n, in the sphere.
3. Determine pressure in sphere. Since n, V, and T are known by this point, use ideal gas law.
 

FAQ: 1 gram of C3H8 gas and 1 gram of O2 gas are delivered

What is the chemical formula for C3H8 gas and O2 gas?

The chemical formula for C3H8 gas is propane (C3H8) and for O2 gas is oxygen (O2).

What is the molar mass of 1 gram of C3H8 gas and 1 gram of O2 gas?

The molar mass of propane (C3H8) is approximately 44 grams per mole, while the molar mass of oxygen (O2) is approximately 32 grams per mole. Therefore, 1 gram of each gas would contain approximately 0.0227 moles of propane and 0.0313 moles of oxygen.

What is the total number of moles of gas delivered in this scenario?

Since 1 gram of C3H8 gas contains 0.0227 moles and 1 gram of O2 gas contains 0.0313 moles, the total number of moles of gas delivered would be 0.054 moles.

What is the volume of gas delivered at standard temperature and pressure (STP)?

At STP (0°C and 1 atm), 1 mole of any ideal gas occupies a volume of 22.4 liters. Therefore, 0.054 moles of gas would occupy a volume of approximately 1.21 liters.

What type of reaction would occur when C3H8 gas and O2 gas are delivered?

When C3H8 gas and O2 gas are combined, a combustion reaction would occur, resulting in the formation of carbon dioxide (CO2) and water (H2O). The balanced chemical equation for this reaction is: C3H8 + 5O2 → 3CO2 + 4H2O.
