Cellular respiration is an exothermic chemical reaction.
Explanation:
Energy is the ability to perform a job or to produce heat. Chemical reactions involve a rearrangement of atoms between substances with rupture or formation of chemical bonds and this generates changes in the energy of the system.
An exothermic reaction is one where energy is released from the system into the environment in the form of heat.
Cellular respiration is carried out in the mitochondria of the cells. There the oxygen absorbed from the external environment is combined with carbohydrates (raw material) to release the chemical energy they contain. Water vapor and carbon dioxide are also released.
Then, <u><em>Cellular respiration is an exothermic chemical reaction.</em></u>
Explanation: Cellular respiration will release energy (exothermic), and the atoms in the reactants will rearrange into something else, a chemical change.
Mg2+...because it loses 2 electron which is on its valence shell making it empty and making it have jst 2 shells. The radius calculated from d nucleus to the new valence shell is then smaller than that of Cl^- and k+
The best conductor of heat would be the material that melted the ice fast. A.K.A. the one with the least amount of minutes. Since aluminum has the least, it is the best conductor of heat
