Question: How many atoms of a chlorine element would be needed to react with one atom of helium?

Answer: So... for the element of CHLORINE, you already know that the atomic number tells you the number of electrons. That means there are 17 electrons in a chlorine atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and seven in shell three.

Hope this helps!.

1. The first four-legged animals to reach land were classified as

andrezito [222]

Explanation:

The first four-legged animals to reach land were classified as tetrapods the term tetra means four. So tetrapods refer to animals with four limbs.
Pangaea also known as Pangea was a supercontinent during the late Paleozoic and Mesozoic times. It incorporated almost the earth's land masses. The formation and breaking up of continents is a geological cyclic process. And there seemed to have many supercontinents that existed before Pangaea. And according to the sources it assembled from the earlier continental parts approximately 335 million of years ago.
Glaciation is a geographical term that explains the formation, movement, and recession of the glaciers and this process was much more evident in times when the world was covered with ice sheets. Glaciers are nothing but in simple words huge chunks of ice which gets accumulated over a period of time, whose movement is governed by its own weight. Due to this ice layers are built which keep on growing slowly together forming a thick mass of ice.
Waterbody never stops moving and this tidal movement brings a lot of changes in the environment around- flora and fauna. However, global warming causing the melting of ice and glaciers has impacted heavily on this causing the extinction of certain species.
Earlier when these environmental changes were not so rapid, marine life in terms of flora and fauna flourished underwater. There was no soil erosion, seawater contamination in terms of industrial waste being released and other contaminants causing loss of marine life.

The value of Ka for phenol (a weak acid), C6H5OH, is 1.00×10-10. Write the equation for the reaction that goes with this equilib

I am Lyosha [343]

Answer:

$Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}$

Explanation:

Hello,

In this case, weak acids are characterized by the fact they do not dissociate completely, it means they do not divide into the conjugated base and acid at all, a percent only, which is quantified via equilibrium. In such a way, the chemical equation representing such incomplete dissociation is said to be:

$C_6H_5OH\rightleftharpoons C_6H_5O^-+H^+$

Thus, we can write the law of mass action, which consider the equilibrium concentrations of all the involved species, which is also known as the acid dissociation constant which accounts for the capacity the acid has to yield hydronium ions:

$K=Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}$

Best regards.
