The large number of areas covered by the chemical energetics can be explained by the different forms in which chemical energy can be released: heat and combustion work, electrical energy in electrochemistry, radiant energy in chemiluminescent systems.
The chemical energy provided by a reaction reflects the energy balance associated with the electronic modifications suffered by the species involved.
From an energy point of view, a chemical reaction between molecules can be schematized in two stages. The first requires a supply of energy and corresponds to the rupture of the bonds of the reactant molecules with release of the atoms which constitute them.
The second releases energy and concerns the creation, by recombination of these atoms, of new bonds entering the structure of the reaction molecules.
As a general rule, the energy released in the second stage is greater than the first. We are talking about exothermic reaction. The difference between these two energies (reaction enthalpy) measures the amount of chemical energy transferred to the external environment.
It is conceivable that this quantity translates, not only the number, but also the strength of the connections involved.
Answer:
The smallest unit of matter is an atom.
Explanation:
It is an atom because an atom is the smallest thing, that has weight and takes up space.
It can also be called a column.
Could cause loss of animal habitats or more animals can become extinct because the more we built the more we are pushing them from there homes.
Answer:
-Malnutrition ( undernutrition)
Malnutrition is a condition in which an individual meal contains principally of a particular class of food, while other classes are deficient. In this case, Leela ,should be have consumed too much rice,CHO( Thailand is associated with high rice production) with less protein and other nutrients .These therefore affects her nutritional and electrolyte balance.
A well balanced diet which contains all the needed classes of food in correct proportion should be taken,
