Final answer:
Chemistry is the study of the properties, composition, and structure of substances, and the transformations they undergo. It also deals with the energy exchanges in these processes. As "The Central Science", chemistry interrelates with numerous other scientific disciplines.
Explanation:
Chemistry, often referred to as "The Central Science", is a branch of science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes. It plays a vital role in multiple disciplines such as biology, medicine and environmental science. It allows us to understand the makeup of substances, from the atomic level to complex molecules, and how they interact through chemical reactions.
One example of a branch of Chemistry is thermochemistry, which focuses on relationships between heat, work, and other types of energy in physical and chemical processes. Dalton's atomic theory, investigating quantitative and qualitative aspects of chemistry, also developed the concept of atomic mass units, allowing for the calculation of formula mass and the quantitative description of substances.

Answer: 1) absorbed
Explanation:
As a chemical bond is formed either by transfer of electrons or sharing of electrons, in order to break the forces of attraction among atoms, energy must be absorbed.
Energy is produced or released when a chemical bond is formed.
Energy is never destroyed, it converts from one form to another.
To break a chemical bond, energy must be .
Further explanation:
The attraction existing between atoms and molecules that facilitate the formation of various chemical compounds is termed as a chemical bond. It is formed either due to electron transference or by electron sharing between the bonded atoms. The chemical bond formed as a result of electron transfer from one atom to another is known as an ionic bond. The bond formed by the mutual sharing of electrons is called a covalent bond.
Endothermic process
The basic meaning of “endo” is “in”. These processes need energy from the surroundings, generally in the form of heat. Photosynthesis, evaporation of water, sublimation of dry ice, and melting of ice are some of the examples of endothermic processes.
Exothermic process
The general meaning of “exo” is “out”. These processes release energy from the system to the surroundings in the form of heat. Combustion of fuels, thermite reactions, nuclear reactions, and neutralization reactions are some examples of exothermic processes.
Since bond breaking is an endothermic reaction, energy must be supplied or absorbed from the surroundings to the system. Therefore, option (1) is the correct answer.

Answer: The molecule identified with the letter C. HFO.
Explanation:
1) In covalent bonds, the dipolesare identified with an arrow pointing from the least electronegative element toward the most electronegative element.
2) The molecule HFO is formed by one covalent bond between H and O, and other covalent bond between F and O.
3) O is more electronegative than H, so in the H-O bond the dipole is identified with the arrow from the H atom toward the O atom. That is correctly indicated in the drawing C, in this way:
-|----→
H - O
4) F is more electronegative than O, so in the O-F bond the dipole is identified with an arrow from the O atom toward the F atom. That is correctly indicated in this way:
-|---→
O - F.
