How much energy in kJ is released when 345g of propane C3H8 is burned according to the following chemical equation?
How much energy (in kJ) is released when 345g of propane (CzHs) is burned according to the following chemical equation? (2 points) C3H8 + 502 3CO2 + 4H20 AH = -2200 kJ 2.
How do you calculate the enthalpy of combustion of propane?
Calculate the standard enthalpy of combustion of propane
- (2) H2(g) + 1/2 O2(g) ==> H2O(l) …
- (3) 3C(s) + 4H2(g) ==> C3H8(g) …ΔH = -104 kJ/mol.
- Using Hess’ Law we can perform the following operations:
- copy eq. (
- copy eq. (
- reverse eq. (
- Add these three equations and cancel and combine where appropriate to obtain…
What is the heat of reaction of propane with oxygen expressed in kilojoules per mole of C3H8 burned?
2220 kJ
2220 kJ is released for every 1 mol C3H8 and 5 mol O2 and 3 mol CO2 and 4 mol H2O. Conduct a chemical reaction in aqueous solution, and measure the change in temperature of the solution.
What is the molecular mass of propane?
44.1 g/mol
Propane/Molar mass
What is the vapor density of propane?
1.882 kg/m³
The vapour density of propane is 1.882 kg/m³ at 0°C (32°F).
What mass of propane is necessary to react with the amount of oxygen?
Answer: 72.6 g of oxygen are needed to burn 20 g of propane.
What is the molecule of propane?
The propane chemical structure, or chemical formula, is three carbon atoms branched with eight hydrogen atoms (C3H8). This atomic makeup of a propane molecule means propane is a “simple” alkane that is clean-burning, with little smoke or odor.
What is the boiling point of propane?
-43.6°F (-42°C)
Propane/Boiling point
What is LPG Vapour?
LPG is both a liquid and a vapor within the cylinder (gas). Propane is a vapor under pressure or at lower temperatures. Propane is odorless, colorless, and has the appearance of water. The LPG gas cylinder-bottle pressure and temperature relation are shown in the table below.
What is the vapor pressure of 100\% propane?
The vapor pressure of propane (C3H8) depends on the temperature. Vapor pressure of 100\% propane: Note! The metric chart indicates gauge pressure. The Imperial chart indicates absolute pressure. Imperial gauge pressure can be calculated as. psig = psia – 14.7 (psi)
Why can’t I vaporize propane in a propane cylinder?
The propane in the cylinder can’t vaporize fast enough to satisfy the demand of the furnace. Let’s look at vaporization from another angle using a railroad steam locomotive which requires liquid (water) that is heated to a boiling point which in turn produces the steam (water vapor) powering the locomotive along the tracks.
What is the molecular weight of propane in grams?
›› Propane molecular weight. Molar mass of C3H8 = 44.09562 g/mol. Convert grams Propane to moles or moles Propane to grams. Molecular weight calculation: 12.0107*3 + 1.00794*8 ›› Percent composition by element
What is the process of propane vaporization?
Vaporization is the process of a liquid being converted into a gas (or vapor). As propane boils, it is in the process of vaporizing. Water boils at 212°F at which point it converts to a vapor we know as steam. Propane works the same way but at a much lower boiling point. One might refer to propane vapor as “LP Gas steam”.
