Answer:

En química, la reactividad de una especie química es su capacidad para reaccionar en presencia de otras sustancias químicas o reactivos (de diferente dominio químico).1

Se puede distinguir entre la reactividad termodinámica y la reactividad cinética. La primera distingue si la reacción está o no favorecida por entalpía (competencia entre energía y entropía), es decir si es una reacción espontánea o no. La segunda distingue si la reacción tendrá lugar o no en una escala de tiempo dada.

De esta forma, existen reacciones termodinámicamente favorables pero cinéticamente impedidas, como la combustión de grafito en presencia de aire. En casos así, la reacción se dará de una forma muy lenta o, directamente, no se producirá. Si una reacción se encuentra bloqueada cinéticamente, es posible lograr que se produzca alterando las condiciones de reacción o utilizando un catalizador.

La química orgánica y la química inorgánica estudian la reactividad de los distintos compuestos. La fisicoquímica trata de calcular o predecir la reactividad de los compuestos, y de racionalizar los mecanismos de reacción.

The way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.

Given an incomplete sentence related to hypothesis and astronomy.

We are required to complete the sentence.

A hypothesis is basically a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.

Astronomy is basically the study of everything in the universe beyond Earth's atmosphere.

The statement can be completed by "do experiments and observations about the prediction of the hypothesis".

Hence the way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.

In 50 words or less, summarize why a résumé and letters of recommendation are important in the college admissions process.

nevsk [136]

Everybody wants to get into college but colleges can accept only so many students each year. Thus, the selection process is run based on students' resumes and letters of recommendation when only the best and the most deserving students are accepted.
