The equilibrium reaction is
N2O4(g)<----> 2NO2(g)
For reaction
Kp = (pNO2)^2 / pN2O4
Given:
Kp = 0.316
pN2O4 = 3.48 atm
To calculate
pNO2 = ?
0.316 = (pNO2)^2 / 3.48
(pNO2)^2 = 1.0997
pNO2 = 1.049 atm
Answer:
d. ΔH° > 0, process is endothermic.
Explanation:
Cold packs contain ammonium nitrate (NH₄NO₃). When this salt dissolves in water, it decreases the temperature of the surroundings. This happens because the process is endothermic (absorbs heat from the surroundings). By convention, when a process is endothermic, the standard enthalpy carries a positive sign (ΔH° > 0).
Deposition is your answer
Answer:
U-235 is an isotope of uranium
Explanation:
The most stable form of uranium isotopes is 235. (0.7198–0.7202%)
Each species is a separate type of organism.
- A species is a group of creatures that share similar traits. The same species of organisms are capable of sexual reproduction as well as interbreeding and producing fertile offspring. It is a fundamental unit of taxonomy and classification.
- The system is divided into seven categories: Kingdom, Phylum or Division, Class, Order, Family, Genus, and Species. Kingdom is the most inclusive category.
- In a group, many types of an organism can be included even if they do not share the same traits. But species is a group of organisms that share similar traits.
- For example, human beings are species as they are all alike in physical features, way of reproduction, etc. But the animal is considered a group because it included a variety of living beings.
Therefore, Each species is not considered a group.
