Answer:
D
Explanation:
Divide the mass by the volume.
The energy that is lost from the generator becomes “unusable”. This energy was emitted as heat or mechanical energy, rather than electrical energy. Energy can never be destroyed, and it wouldn’t be considered lost if it was converted into the intended product.
Answer:
-The reactants have less heat energy than the products.
Explanation;
-An endothermic reaction is a reaction in which heat energy is absorbed from the surroundings. In such a reaction the energy of the reactants is less than the energy of the products and therefore the enthalpy change is positive, greater than zero.
As a conjugate base of a strong acid,ClO4-would be classified as having a negligible basicity. The basicity of a chemical species is normally expressed by the acidity of the conjugate acid. The basicity of an acid is the number of hydrogen ions, which can be produced by one molecule of the acid.
