Environmental science is an interdisciplinary field which extends into other fields.
The environment refers to all that is around us, a scientist studying environment science needs to know how chemical reactions occur in the environment and how this affect the organisms living in the environment. Geology involves the extraction of minerals and other resources from the interior of the earth, an environmental scientist needs to know how the activities of the geologists affect the environment. For instance, how does oil spillage during crude oil drilling affect the organisms living in the water.<span />

For the reaction 4FeCl2(aq) + 3O2(g) → 2Fe2O3(s) + 4Cl2(g), what volume of a 0.945 M solution of FeCl2 is required to react comp
Mnenie [13.5K]

Answer:

0.01M

Explanation:

Given paramters:

Volume of FeCl₂ = ?

Concentration = 0.945M

Number of molecules of O₂ = 4.32 x 10²¹molecules

Solution:

The balanced reaction equation is given below:

           4FeCl₂ + 3O₂ → 2Fe₂O₃ + 4Cl₂

Now, to solve the problem we use mole relationship between the compounds.

We work from the known to the unknown compounds. Here, the known is the oxygen gas because from the given parameters we can estimate the number of moles of the reacting gas.

  number of moles of O₂ = \frac{number of elementary of particles}{6.02 x 10^{23}}

number of moles of O₂ =  \frac{4.32 x 10^{21}}{6.02 x 10^{23}}

number of moles of O₂ = 0.007mole

now, from the reaction equation we find the number of moles of the FeCl₂:

   3 mole of O₂ reacted with 4 moles of FeCl₂

0.007mole of O₂ reacted with \frac{4 x 0.007}{3} = 0.0096mole O₂

Now to find the volume of FeCl₂ we use the expression below;

       volume of FeCl₂ = \frac{number of moles}{concentration}

                                   =  \frac{0.0096}{0.945}

                                    = 0.01L

Convert a pressure of 0.0248 mm Hg to the equivalent pressure in pascals (Pa).
drek231 [11]

Answer is 3.306 Pa.


<em>Explanation:</em>


This is a simple unit conversion problem.

1 atm = 760 mmHg = 101325 Pa


Hence,

    0.0248 mmHg = (101325 Pa / 760 mmHg) x 0.0248 mmHg

                           = 3.306 Pa


Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.


The relationships among those units as follows

1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg
