Answer:
the solution is acidic as its ph has already exceeded the neutral level
The energy of motion predominates in gases, whereas the energy of attraction between particles predominates in solids. In contrast to gases, which lack both defined volume and shape, solids have both.

What do you mean by solid?
One of the three fundamental states of matter, along with liquid and gas. (Ionized gases or plasmas are occasionally regarded as the fourth state of matter.) Because the energy of atoms lowers when they occupy a reasonably organized, three-dimensional structure, a solid develops from a liquid or gas. Solids differ from liquids and gases in that they have certain properties. For instance, all solids can withstand forces that are parallel or perpendicular to a surface (i.e., normal or shear loads, respectively). These characteristics are influenced by the atoms that make up the solid, their arrangement, and the forces that exist between them.

Answer:
Because both carbon and oxygen are demanded to obey the octet's rule.
Explanation:
Hello.
In this case, recalling the Lewis dot structure of CO₂ which is basically:
We know oxygen has six valance electron whereas carbon four valence electrons, it means that oxygen needs two electrons in order to attain eight electrons and carbon needs four electrons for the same purpose. In such a way, as carbon dioxide contains one carbon atom and two oxygen atoms we infer that each oxygen is providing two electrons for a total of four to allow the carbon obey the octet as well as oxygen and this is attained via two double bonds.
Best regards.
