Answer:

La Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC) en su Artículo 1, lo define como ‘un cambio de clima atribuido directa o indirectamente a la actividad humana que altera la composición de la atmósfera mundial y que se suma a la variabilidad natural del clima observada durante períodos de tiempo comparables’. La CMNUCC distingue entre ‘cambio climático’ atribuido a actividades humanas que alteran la composición atmosférica y ‘variabilidad climática’ atribuida a causas naturales.

Los científicos han encontrado evidencias de que el clima en el planeta está cambiando a un ritmo más acelerado de lo esperado y que nuestras actividades ligadas a la producción, extracción, asentamiento y consumo, son la principal causa de este aceleramiento en el cambio.

El mayor problema de un cambio acelerado en el clima es que nuestras sociedades no están preparadas para asumir los cambios que esto nos pueda traer: derretimiento de las masas glaciares y nevados que abastecen acueductos, cambios en los ciclos de floración y fructificación de las plantas de cultivo, ascensos en el nivel de los mares donde hay mucha población viviendo, mayor ocurrencia y fuerza en lluvias, sequías, huracanes, heladas y granizadas en áreas urbanas y rurales, entre otros fenómenos que sin duda reducen nuestra calidad de vida.

As temperature increases, pressure increases as well. ... As temperature increases, the molecules move faster, increasing the number of collisions and the force of collisions between the molecules and the walls of the container. This increases the pressure on the walls of the container.

In the Haber Process, hydrogen (H2) and nitrogen (N2) react to produce
lesya692 [45]

Answer:

Mass stays the same because no matter is created or destroyed.

Explanation:

Regardless of what chemical reaction we have, in each case the law of mass conservation applies. The law of mass conservation states that the total mass of a reaction mixture is kept constant, as mass cannot be created or destroyed.

In this specific reaction, the total mass of the reactants should be equal to the total mass of the products when the reaction is complete.

In other words, if we add the mass of hydrogen to the mass of nitrogen, when the reaction is compete, assuming no reagent in excess, this should be equal to the mass of ammonia formed.

2 HI(g) ⇄ H2(g) + I2(g) Kc = 0.0156 at 400ºC 0.550 moles of HI are placed in a 2.00 L container and the system is allowed to rea
Alex_Xolod [135]

<u>Answer:</u> The concentration of hydrogen gas at equilibrium is 0.0275 M

<u>Explanation:</u>

Molarity is calculated by using the equation:

\text{Molarity}=\frac{\text{Number of moles}}{\text{Volume of solution (in L)}}

Moles of HI = 0.550 moles

Volume of container = 2.00 L

\text{Initial concentration of HI}=\frac{0.550}{2}=0.275M

For the given chemical equation:

                          2HI(g)\rightleftharpoons H_2(g)+I_2(g)

<u>Initial:</u>                  0.275

<u>At eqllm:</u>           0.275-2x      x         x

The expression of K_c for above equation follows:

K_c=\frac{[H_2][I_2]}{[HI]^2}

We are given:

K_c=0.0156

Putting values in above expression, we get:

0.0156=\frac{x\times x}{(0.275-2x)^2}\\\\x=-0.0458,0.0275

Neglecting the negative value of 'x' because concentration cannot be negative

So, equilibrium concentration of hydrogen gas = x = 0.0275 M

Hence, the concentration of hydrogen gas at equilibrium is 0.0275 M

Is the asthenosphere or the lithosphere closer to the outer core
Murrr4er [49]
The asthenosphere is directly below the lithosphere so the answer to your question is the asthenosphere, because the outer core is towards the center of Earth.
