Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. The hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and phosphoric acid (Pi) releases energy (it is an exergonic reaction).
Answer:
B) Heat is given off.
Explanation:
When heat is given off, a chemical change must have occurred and such a reaction is termed an exothermic reaction.
A chemical change is one in which;
- the process is not easily reversible
- leads to the production of new kinds of matter
- involves change in mass
- requires a considerable amount of energy.
Most chemical reactions are accompanied by heat changes.

Answer:
Explanation:
Columns and rows used in the periodic classification of elements shows trends in the properties of elements.
The periodic columns are called groups and they denote vertical arrangement of elements.
The horizontal rows are the periods.
- Groups and Periods provides a very simple way to classify elements.
- They reflect trends among different elements that are found in nature. Following these groups and periods, it is even possible to predict the nature of an undiscovered element.
- Certain parts of the table have some unique elements on them with some distinctive properties that distinguish them from others.
- The atomic number is the basis of this classification. By this, it is possible to delineate that elements with similar properties are located on the same group.
