Answer:
Explanation:
During an exothermic reaction bonds break and new bonds form and protons and electrons go from a structure of higher potential energy to lower potential energy. During this change, potential energy is converted to kinetic energy, which is the heat released in reactions. In an endothermic reaction the opposite occurs.

Explanation:
The mass and volume are thephysical properties that define matter. A matter is anything that can be seen or touched and is said to have mass, volume, density, and occupies space.
A matter is a substance present in the universe that occupies space and is said to have a definite volume and mass. Based on its physical arrangement and composition the matter can be gas, liquid, plasma, or solid.
The mass, volume, and density define the matter and its particles with specific mass and sizes due to the presence of sub-atomic particles like neutron, electron, and proton.
The amount of matter in the universe can be measured in kilograms and grams as mass, and the space occupied by it in cubic meters (m³) as volume.
Therefore, the matter is said to have volume and mass.

Answer:
lithium chloride
Explanation:
Li=Lithium
Cl=Chlorine
The correct name for LiCl is Lithium Chloride. It's an ionic compound composed of Lithium and Chloride ions, arranged in a lattice structure with Chloride ions contacting each other across diagonally on the face of a unit cell.
The correct name for LiCl is simply Lithium Chloride. This is an ionic compound, which means it is composed of two ions: the lithium ion (Li+) and the chloride ion (Cl-). In this case, Li (Lithium) loses an electron and becomes a cation (Li+), whereas Cl (Chlorine) gains that electron and becomes an anion (Cl-). The compound LiCl is then formed from the electrostatic attraction between these ions.
On the face of a LiCl unit cell, Chloride ions contact each other across the diagonal of the face, showing the close packing arrangement of the ions in the lattice structure of the compound.
It's worth noting that the common naming system for these types of compounds is quite straightforward. The name of the positive ion (the cation) comes first (Lithium), followed by the name of the negative ion (the anion) with an -ide suffix (Chloride).
