Ethanol (c2h5oh) is currently blended with gasoline as an automobile fuel. calculate the heat produced per liter of ethanol by combustion of ethanol under constant pressure. ethanol has a density of 0.789 g/ml.

-2.34 × 10⁴ kJ/L

Explanation:

Let's consider the reaction for the combustion of ethanol.

C₂H₅OH(l) + O₂(g) ⇒ CO₂(g) + H₂O(l)

The enthalpy of combustion (heat rteleased under constant pressure) of ethanol is -1366.8 kJ/mol. Considering the molar mass of ethanol is 46.07 g/mol, the heat produced per liter of ethanol is:

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

the answer is c
