Answer:
The speed of light becomes slower in denser medium which is water in this case.
Explanation:
We know the lens law of Refraction which states
Refractive index of second medium /Refractive index of the first medium
= Velocity of light in medium 1 (V1)/ velocity of light in medium 2 (V2)
When light rays fall from air medium into water which is a denser medium bending of light or change in the direction of light occurs which is knows as Refraction.
When refraction occurs speed of the light rays are also varied as we can see it from the Lenz's Law. suppose two light rays parallel to each other falling on the air-water interface at an angle , the first ray will reach the interface and bend about the normal and then the second ray. We also observe when light enters denser medium the speed of light becomes slower, also the bending of light when going from rarer to denser it bends towards normal of the surface and when it move from denser to rarer medium it moves away from the normal to the surface.
Explanation:
there are three basic types of soils sand silt and clay . But most soils are composed of a combination of the 3 different types.
Answer:
Matter is the Stuff Around You
Matter is everything around you. Atoms and compounds are all made of very small parts of matter. ... Matter is defined as anything that has mass and takes up space (it has volume).

Explanation:
The reaction equation will be as follows.
![CO_{2}(aq) + H_{2}O \rightleftharpoons H^{+}(aq) + HCO^{-}_{3}(aq)](https://tex.z-dn.net/?f=CO_%7B2%7D%28aq%29%20%2B%20H_%7B2%7DO%20%5Crightleftharpoons%20H%5E%7B%2B%7D%28aq%29%20%2B%20HCO%5E%7B-%7D_%7B3%7D%28aq%29)
Calculate the amount of
dissolved as follows.
![CO_{2}(aq) = K_{CO_{2}} \times P_{CO_{2}}](https://tex.z-dn.net/?f=CO_%7B2%7D%28aq%29%20%3D%20K_%7BCO_%7B2%7D%7D%20%5Ctimes%20P_%7BCO_%7B2%7D%7D)
It is given that
= 0.032 M/atm and
=
atm.
Hence,
will be calculated as follows.
=
= ![0.032 M/atm \times 1.9 \times 10^{-4}atm](https://tex.z-dn.net/?f=0.032%20M%2Fatm%20%5Ctimes%201.9%20%5Ctimes%2010%5E%7B-4%7Datm)
= ![0.0608 \times 10^{-4}](https://tex.z-dn.net/?f=0.0608%20%5Ctimes%2010%5E%7B-4%7D)
or, = ![0.608 \times 10^{-5}](https://tex.z-dn.net/?f=0.608%20%5Ctimes%2010%5E%7B-5%7D)
It is given that ![K_{a} = 4.46 \times 10^{-7}](https://tex.z-dn.net/?f=K_%7Ba%7D%20%3D%204.46%20%5Ctimes%2010%5E%7B-7%7D)
As, ![K_{a} = \frac{[H^{+}]^{2}}{[CO_{2}]}](https://tex.z-dn.net/?f=K_%7Ba%7D%20%3D%20%5Cfrac%7B%5BH%5E%7B%2B%7D%5D%5E%7B2%7D%7D%7B%5BCO_%7B2%7D%5D%7D)
= ![2.71 \times 10^{-12}](https://tex.z-dn.net/?f=2.71%20%5Ctimes%2010%5E%7B-12%7D)
= ![1.64 \times 10^{-6}](https://tex.z-dn.net/?f=1.64%20%5Ctimes%2010%5E%7B-6%7D)
Since, we know that pH = ![-log [H^{+}]](https://tex.z-dn.net/?f=-log%20%5BH%5E%7B%2B%7D%5D)
So, pH = ![-log (1.64 \times 10^{-6})](https://tex.z-dn.net/?f=-log%20%281.64%20%5Ctimes%2010%5E%7B-6%7D%29)
= 5.7
Therefore, we can conclude that pH of water in equilibrium with the atmosphere is 5.7.
