I’m confused.. there is no picture or anything describing anything you want done...
The Sydney Opera House is located in Australia.
You have to add the passage.
Answer:
The sign of H is positive, and the products have more potential energy than the reactants.
Explanation:
The options you were given are the following:
- The sign of H is positive, and the products have less potential energy than the reactants.
- The sign of H is positive, and the products have more potential energy than the reactants.
- The sign of H is negative, and the products have less potential energy than the reactants.
- The sign of H is negative, and the products have more potential energy than the reactants.
An endothermic reaction is a chemical reaction that absorbs heat from the surroundings. The absorbed energy provides the activation energy for the reaction to occur.
The sign of H refers to the change in enthalpy. Enthalpy is the thermodynamic property of a system. It is the sum of the internal energy added to the product of the pressure and volume of the system:
If the pressure and volume are constant, the change in enthalpy equals the transferred heat (q). If <em>q</em> is positive, we have an endothermic reaction. The change in enthalpy (the sign of H) in that case always positive, as the change in internal energy is positive (heat is absorbed).

Refer below.
Explanation:
The creator does exclude an area investigating counterarguments or an end.
In spite of the fact that there are numerous outstanding instances of fruitful journalists who were known—in any event to a limited extent—for their lethargy, instances of individuals who were effective as an immediate consequence of their tirelessness possess large amounts of a wide scope of controls. Michael Jordan, for instance, is broadly viewed as one of the best ball players ever. During his profession, he was known for his tenacious seriousness and scrupulousness. Among writers, Ray Bradbury was known for keeping in touch with one short story consistently—a shocking pace of creation. What's more, numerous other fruitful creators have set page amounts and severe timetables for themselves. Along these lines, while downgrading profitability may have worked for a few, concentrating eagerly on it has worked for some others.
I discover my counterargument genuinely compelling. The creator's contention fundamentally comprises of narrative proof. It would be compelling if the entirety of the accessible proof bolstered the focal case. However, the measure of narrative proof that doesn't bolster the case debilitates the creator's contention and reinforces my counterarguement.
