Kaylis [27]2 years ago

Answer:

The correct answer is - D) 1000x.

Explanation:

pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the   H+ concentration in acidity/basicity. The more  H +  ions found in solution, the more acidic the substance is as acids donate  H +  ions.  

You can calculate the concentration of  H +  from the pH and the equation  

p H  = − log [ H + ]

arrange again

[ H + ]  =  10 − p H

So for a pH of 8, we get  [ H + ]  = 10 ^− 8

For a pH of 5, we get  [ H + ] = 10^ − 5

 10 ^−5  /10 ^− 8= 10 ^3

=  1000

Please help i give 48 points !!!which correctly lists the three layers in which water moves easily
Aliun [14]

soil, rock, organic layer

Explanation:

Permeability is the ability of a layer of rock to transmit fluid such as oil or water

The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter

Rocks such as gravels, and  sparingly cemented sands have high permeability

The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water

Therefore, water moves easily between layers  soil, rock, organic layer
