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:

answerto predict;

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
