Prarie Grass Protects soil ( And this is just what I think, so I am sorry if I am wrong)
But I think that the grass is there so that the dirt doesn't fly away.
Gases have high kinetic energy: the molecules are moving much more than in a liquid or solid. You can cut out A and B. In the liquids, the difference is temperature. If a lower temperature is closer to being solid, and a solid has lower kinetic energy than a liquid, then C is the answer. Hope this helps.
Answer:
2.13 g
Explanation:
(142.04)(0.0150) = 2.13 g
The electrons that are in the outermost electron shell, also known as the valence shell, have more energy then those in the inner electron shells, I hope this helps<3
Answer:
51096J/mol = Energía de activación para el proceso del canto
Explanation:
Podemos solucionar este problema usando una forma de la ecuación de Arrhenius:
Donde K representa la velocidad de reacción (En este caso, la velocidad a la que cantan los grillos), Ea es la energía de activación, R la constante de los gases (8.314J/molK) y T representa la temperatura absoluta de 1, el estado inicial y 2, el estado final.
Estado inicial: K1 = 2.0x10²; T1 = 27°C + 273.15 = 300.15K
Estado final: K2 = 39.6; t2 = 5°C + 273.15 = 278.15K
Reemplazando en la ecuación:
<h3>51096J/mol = Energía de activación para el proceso del canto</h3>
