Answer:

11.97 L

Explanation:

Given :

⇒ Number of moles, n = <u>0.5 mol</u>

⇒ Temperature, T = 15 °C = <u>288 K</u>

⇒ Pressure, P = <u>1.1 atm</u>

Solving using Ideal Gas Equation :

⇒ PV = nRT

⇒ V = 0.5 × 8.314 × 288 / 1.1

⇒ V = 144 × 8.314 / 1.1

⇒ V = 1197.216 m³ = 11.97 L (approx.)

  • T=15+273=298k
  • P=1.1atm
  • n=0.5mol

Apply ideal gas equation

  • PV=nRT
  • V=nRT/P
  • V=0.5(8.314)(298)/1.1
  • V=1126.16mL
  • V=1.12L

How do molecular shape affect polarity
devlian [24]
The shape of the molecule will determine the direction of each of the individual bond dipoles, and thus, will always play a role in determining the polarity of the molecule as a whole.

The average propane cylinder for a residential grill holds approximately 18 kg of propane. How much energy (in kJ) is released b

Combustion is a chemical reaction between a fuel and an oxidant, oxygen, to give off combustion products and heat. Complete combustion results when all of the fuel is consumed to form carbon dioxide and water, as in the case of a hydrocarbon fuel. Incomplete combustion results when insufficient oxygen reacts with the fuel, forming soot and carbon monoxide. 

The complete combustion of propane proceeds through the following reaction:
C_{3} H_{8} + 5O_{2} --> 3CO_{2} + 4H_{2}O

Combustion is an exothermic reaction, which means that it gives off heat as the reaction proceeds. For the complete combustion of propane, the heat of combustion is (-)2220 kJ/mole, where the minus sign indicates that the reaction is exothermic. 

The molar mass of propane is 44.1 grams/mole. Using this value, the number of moles propane to be burned can be determined from the mass of propane given. Afterwards, this number of moles is multiplied by the heat of combustion to give the total heat produced from the reaction of the given mass of propane.

 14.50 kg propane  x <u> 1000 g </u> x <u>  1 mole propane   </u>  x <u>  2220 kJ  </u>   
                                     1 kg              44.1 g                     1 mole

= 729,931.97 kJ
