INFORMATION:
We have the following statements
And we must complete them
STEP BY STEP EXPLANATION:
To complete the statements, we need to classify matter according to its state:
- Solid:
there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
- Liquid:
That describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
- Gas:
That describes the gas state, which we will consider in more detail elsewhere. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either.
Finally, we know that:
- A solid has a definite volume and has a definite shape
- A liquid has a definite volume and has not a definite shape
- A gas has not a definite volume and has not a definite shape
ANSWER:
- A solid has a definite volume and has a definite shape
- A liquid has a definite volume and has not a definite shape
- A gas has not a definite volume and has not a definite shape
Answer:
Explanation:
Hello,
In this case, the enthalpy of combustion is understood as the energy released when one mole of fuel, in this case octene, is burned in the presence of oxygen and is computed with the enthalpies of formation of the fuel, carbon dioxide and water as shown below (oxygen is circumvented as it is a pure element):
Thus, since we already know the enthalpy of combustion of the fuel, for carbon and water we have -393.5 and -241.8 kJ/mol respectively, thereby, the enthalpy of combustion turns out:
Best regards.
