Answer:
Basing on explanations below;
1. Endothermic reactions have a positive enthalpy while Exothermic reactions have a negative enthalpy.
2. Endothermic reactions take place in high temperatures while Exothermic reactions take place in low temperatures.
Answer:
The thermal energy is the average kinetic energy of the particles in an object.
Explanation:
Hello!
In this case, since the thermal energy is associated to the temperature and the system and its effect over the molecules in the light of their movements, we infer that the proper answer is:
"The thermal energy is the average kinetic energy of the particles in an object".
On the contrary, we consider that the internal energy is referred to the total energy of the particles in the system and the translational energy is associated to the eventual movement of the system.

Because PE is proportional to the height of where the mass is, and the top of the swing is the highest the mass of the 'bob' ever gets.

(a) sodium hydroxide + ammonium sulfate --> sodium sulfate + ammonium hydroxide
sodium sulfate precipitates in aqueous solutions
(b)<span> niobium(V) sulfate + barium nitrate → Barium sulfate + niobium nitride
both do not precipitate in aqueous solution
</span>(c) strontium bromide + silver nitrate ---> strontium nitrate + silver bromide
both do not precipitate in aqueous solution
