Answer:

The process you are referrring to is erosion.

Explanation:

Weathering would be the breaking down of rock/other land debris. Its more active counterpart would be erosion, wherein the process transports the bits of rock and minerals away. Hope it helps!

When 3243. grams of iron (III) chloride are reacted with 511.8 grams of hydrosulfuric acid, which is the limiting reactant?
AleksAgata [21]

Answer:

Hydrosulfuric acid will act as limiting reactant.

Explanation:

Given data:

Mass of iron(III) chloride = 3243.0 g

Mass of hydrosulfuric acid = 511.8 g

Limiting reactant = ?

Solution:

Chemical equation:

2FeCl₃ + 3H₂S       →       Fe₂S₃ + 6HCl

Number of moles of iron(III) chloride:

Number of moles = mass/molar mass

Number of moles = 3243.0 g/ 162.2 g/mol

Number of moles = 20 mol

Number of moles of hydrosulfuric acid:

Number of moles = mass/molar mass

Number of moles = 511.8 g/ 34.1 g/mol

Number of moles = 15 mol

Now we will compare the moles of both reactant with products

                      FeCl₃          :          Fe₂S₃

                       2                :            1

                      20               :          1/2 ×20 = 10

                      FeCl₃          :            HCl

                       2                :              6

                      20               :          6/2 ×20 = 60

                      H₂S             :          Fe₂S₃

                       3                :            1

                      15               :          1/3 ×15 = 5

                      H₂S            :            HCl

                       3                :              6

                      15                :          6/3 ×15 = 30

Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.

the process of separating a liquid/solid mixture by slowly pouring the liquid component into a new vessel as the solid settles t
olga55 [171]

The process involving separation of liquid/solid mixture as regards this question is Decantation.

  • Decantation can be regarded as one of the process used in separation of liquid from solid as well as  other immiscible (non-mixing) liquids through the removal of  the liquid layer that is present at the top from the layer of solid/liquid which present at the below.
  • In the process, the liquid will be poured slowly into another vessel as the pouring continues, then the solid will settle in the original vessel.
  • This process can be done through tilting the mixture after the the top layer have been poured out.

<em>Therefore, decantation is one of the separation technique.</em>
