For the following reaction, 5.20 grams of propane (C3H8) are allowed to react with 22.5 grams of oxygen gas. propane (C3H8) (g)

Sliva [168]

Answer:

15.58g of CO₂ is the maximum amount that can be produced

Explanation:

The propane reacts with oxygen as follows:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Where 1 mole of propane reacts with 5 moles of oxygen

To solve this question we need to find the moles of propane and oxygen to find limiting reactant using the chemical reaction:

Moles propane -Molar mass: 44.1g/mol-:

5.20g * (1mol / 44.1g) = 0.118 moles

Moles oxygen -Molar mass: 32g/mol-:

22.5g O₂ * (1mol / 32g) = 0.703 moles

For a complete reaction of 0.703 moles of oxygen are:

0.703 moles O₂ * (1mol C₃H₈ / 5mol O₂) = 0.141 moles of propane are necessaries. As there are just 0.118 moles of propane, propane is limiting reactant.

The moles of carbon dioxide that are produced are:

0.118 moles C₃H₈ * (3 moles CO₂ / 1 mol C₃H₈) = 0.354 moles CO₂

The maximum mass that can be produced is -Molar mass CO₂: 44.01g/mol-:

0.354 moles CO₂ * (44.01g / mol) =

15.58g of CO₂ is the maximum amount that can be produced

Compare and contrast chemical potential energy and elastic potential energy

nikdorinn [45]

Chemical Potential Energy is released when chemical bonds between atoms are broken (like covalent and ionic) and is released mainly as thermal
Elastic Potential is released when the molecules in the material are allowed to go back to there original form, and is released mainly as kinetic
