<span>If heat is consumed during a reaction, the reaction is said to be an endothermic reaction.
There are two types of reactions related to heat energy, these are endothermic and exothermic </span>reactions.
Exothermic reactions are when the reactions as it proceeds gives out heat energy to the surroundings. Endothermic reactions are when heat energy is absorbed by the reactants to initiate and continue the reaction. Therefore reaction system absorbs or consumes heat energy from the surrounding.
Factors that influence general adaptation syndrome include that of a person’s health, nutrition, sex, ages, race, socioeconomic status, and genetics. These are factors that are either can precipitate a different reaction, while others are modifiable and unmodifiable traits.
In biology, adaptation has 3 related meanings. Firstly, it is the dynamic evolutionary process that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is a phenotypic trait or adaptive trait, with a functional role in each organism, that is maintained and has evolved through natural selection. Historically, adaptation has been described from the time of the ancient Greek philosophers such as Empedocles and Aristotle. In 18th and 19th century natural theology, adaptation was taken as evidence for the existence of a deity. Charles Darwin proposed instead that it was explained by natural selection. Adaptation is related to biological fitness, which governs the rate of evolution as measured by a change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects. In mimicry, species evolve to resemble other species; in Müllerian mimicry, this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as wasps able to sting) come to advertise their defenses in the same way. Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight. Adaptation is a major topic in the philosophy of biology, as it concerns function and purpose (teleology). Some biologists try to avoid terms that imply purpose in adaptation, not least because it suggests a deity's intentions, but others note that adaptation is necessarily purposeful.
Answer:
The molarity of the solution is 0.29 ![\frac{moles}{liter}](https://tex.z-dn.net/?f=%5Cfrac%7Bmoles%7D%7Bliter%7D)
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
![Molarity=\frac{number of moles of solute}{volume}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7Bnumber%20of%20moles%20of%20solute%7D%7Bvolume%7D)
Molarity is expressed in units
.
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:
![Molarity=\frac{2.1 moles}{7.3 liters}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B2.1%20moles%7D%7B7.3%20liters%7D)
Molarity= 0.29 ![\frac{moles}{liter}](https://tex.z-dn.net/?f=%5Cfrac%7Bmoles%7D%7Bliter%7D)
<u><em>The molarity of the solution is 0.29 </em></u>

The answer is: A molecule with a difference in electrical charge between two ends.
Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
For example fluorine has electronegativity approximately χ = 4 and oxygen χ = 3,5, fluorine attracts electron and he has negative charge and oxygen has positive charge.
<span>I would measure the mass of the solid substance. I would prepare a known mass of room temperature water large enough to submerge the solid substance in question. I would place the water in an insulated container. Then I would heat the solid substance to a known temperature. I would measure the temperature of the heated sample and the water. Then I would submerge the sample in the water and allow the sample and the water to reach the same temperature. I would measure this equilibrium temperature.
I would interpret the difference in temperature between the heated sample and the equilibrium temperature as the change in temperature in the sample. Given the known mass, the beginning temperature of the water, and the equilibrium temperature I can determine how much energy was transferred from the heated sample to the water.
Now the mass of the sample, a change in temperature in the solid substance, and the amount of energy transferred to create the temperature is known. This is sufficient to determine the specific heat of the solid substance</span>
