Answer:
Chemical reaction are irreversible. Some of the example of chemical reaction are cooking, rusting, and burning. During a chemical reaction, the composition of substances changes and the particles rearrange to form a new substance. The new substance formed after chemical reaction of substance has different physical and chemical properties.
When a chemical reaction occur, the atoms or molecules of the substances change its physical and chemical properties such as while cooking of vegetable, the molecules of vegetable undergo changes in their properties and form a new substance which is different from the earlier.
Answer:
High pressure and low temperature, because particles are forced close together and moving slower, so intermolceular forces of attraction increase.
Explanation:
The properties of an ideal gas are explained by the kinetic-molecular theory. An ideal gas assumes there is no intermolecular attraction between the molecules. High pressure would make the particles closer together and interact more, going against the kinetic molecular theory that states there are large spaces between particles and no interactions between particles. Low temperature would make the particles slow which prevents them from overcoming the intermolecular attraction between particles.

HEYA!!
Answer:
biogas
Explanation:
this gas can be produced by mixing methane and carbon dioxide, known as biogas, by fermenting human and animal waste, pig or cattle slurry and faeces, for example, in a buried chamber known as a digester.
