Answer: The material formed by weathering that is then eroded and deposited is called SEDIMENTS.

Explanation:

Weathering is the process by which rocks are broken down to form Sediments. There are three forces that can cause weathering of a rock they include:

- Biological weathering: example tree roots, and lichens.

- Chemical weathering: example, water, acid, or gases.

- Mechanical weathering: example, wind, rain, water freezing.

These Sediments that are generated during the course of weathering is moved from one place to another through a natural force called EROSION. The dropping of the Sediments in a new place is known as deposition. The collective effects of weathering,erosion and deposition leads to:

- landslides

-Changes in shape, size and texture of land forms.

- soil formation

- washes soil, pollutants, harmful sediments into water ways. I hope this helps, thanks.

Calcium hydroxide is a strong base but is not very soluble ( Ksp = 5.02 X 10-6 ). What is the pH of a saturated solution of Ca(O

Misha Larkins [42]

Answer : The pH of a saturated solution is, 12.33

Explanation : Given,

$K_{sp}$ = $5.02\times 10^{-6}$

First we have to calculate the solubility of $OH^-$ ion.

The balanced equilibrium reaction will be:

$Ca(OH)_2\rightleftharpoons Ca^{2+}+2OH^-$

Let the solubility will be, 's'.

The concentration of $Ca^{2+}$ ion = s

The concentration of $OH^-$ ion = 2s

The expression for solubility constant for this reaction will be,

$K_{sp}=[Ca^{2+}][OH^-]^2$

Let the solubility will be, 's'

$K_{sp}=(s)\times (2s)^2$

$K_{sp}=(4s)^3$

Now put the value of $K_[sp}$ in this expression, we get the solubility.

$5.02\times 10^{-6}=(4s)^3$

$s=1.079\times 10^{-2}M$

The concentration of $Ca^{2+}$ ion = s = $1.079\times 10^{-2}M$

The concentration of $OH^-$ ion = 2s = $2\times (1.079\times 10^{-2}M)=2.158\times 10^{-2}M$

First we have to calculate the pOH.

$pOH=-\log [OH^-]$

$pOH=-\log (2.158\times 10^{-2})$

$pOH=1.67$

Now we have to calculate the pH.

$pH+pOH=14\\\\pH=14-pOH\\\\pH=14-1.67=12.33$

Therefore, the pH of a saturated solution is, 12.33

In which species does phosphorous have the highest oxidation number?

nignag [31]

the compounds in which phosphorous posses the highest possible oxidation have to mention here.

The species in which phosphorous have the highest oxidation state are: H₃PO₄, P₂O₅, PCl₅

The possible oxidation state of phosphorous is III and V. The highest oxidation state is V. There are several compounds in which phosphorous posses the +5 oxidation state. Like- Phosphoric acid (H₃PO₄), phosphorous pentoxide (P₂O₅), Phosphorous chloride (PCl₅) etc.

The oxidation state of an element depends upon the valence electron the valence shell of phosphorous is 3s² 3p³. Thus there are 5 electrons, as it has vacant 3d orbital thus it can easily form compound having +5 oxidation state.

Today is Earth day. What is one thing that you can do at school or at home to help protect our home, planet Earth?

omeli [17]

You can start by recycling plastic and paper more often! Pick up trash that you see laying in the street and don’t add to it by littering!
